JOHN DAY FOSSIL BEDS

Oreodont skull, John Day Fossil Beds

More than a 100 groups of mammals and a wide variety of plants have been found in the early Miocene, 39-19 million year old, John Day Formation near Kimberly, Oregon.

The fossiliferous strata that have yielded beautifully preserved specimens of many of the animals we see domesticated today. Dogs, cats, swine and horses are common. Oreodonts, camels, rhinoceros and rodents have also been found in this ancient deciduous forested area.

Here my talented young paleontologist cousin Spencer is holding a well preserved Oreodont skull.Many sites in Oregon yield beautifully preserved fossil shells laid down over 60 million years. The asteroid that hit the Gulf of Mexico at the end of the Cretaceous caused a seafloor rift that split ancient Oregon. The massive hole left behind as the coastal lands slid northward filled in with sediment, refilling the basin.

These marine sediments were uplifted around the time of the birth of Oregon's Coastal Range. Easily collected and identified, as they look very similar to their modern cousins, you can dig for marine fossils all along Oregon's beachfront.

MOSQUE-CATHEDRAL, CORDOBA, SPAIN

A mix of Muslim and Christian architecture can be found in the stunning, and oh so grand Mosque-Cathedral in Cordoba, southern Spain. 

Originally a small temple of Christian Visigoth origin, the Catholic Basilica of Saint Vincent of Lérins has an unusual and collaborative history. 

When Muslims conquered Spain in 711, the church was divided into Muslim and Christian halves.

This sharing arrangement lasted until 784, when the Christian half was purchased by the Emir 'Abd al-Rahman I, who then demolished the original structure to build the grand mosque of Córdoba on its ground.

Córdoba returned to Christian rule in 1236 during the Reconquista, and the building was converted to a Roman Catholic church, culminating in the inclusion of a Renaissance cathedral nave in the 16th century. If you are visiting Andalusia, it is well worth a day trip. Bring your camera and comfortable shoes.

KOTSUIS AND HOHHUG: KWAKWAKWA'WAKA OF THE PACIFIC NORTHWEST

Kotsuis and Hohhug, Nakoaktok

This stunning image of Kotsuis and Hohhug, Nakoaktok — Nakoaktok men in ceremonial dress, with long beaks, crouching on their haunches was taken by Edward Curtis ca. 1914. 

Curtis photographed the Kwakwaka'waka ceremonial dress and masks on the west coast of British Columbia.

The Kwakwa̱ka̱’wakw (or Kwakiutl) are a collective of First Nation groups of the Pacific Northwest Coast. We view them as one people, and they are bound by language, but each had their own Chiefs, beliefs and ancestors. Collectively they cover the territory of British Columbia on northern Vancouver Island, some of the islands around Johnstone Strait and Queen Charlotte Strait and the adjoining mainland. 

United by the common language of Kwak'wala, the broad group can be divided into 13 nations, each with its own clan structure and distinct histories. According to Kwakwaka'wakw folklore their ancestors or ‘na’mima, came to a given spot — by way of land, sea, or underground — in the form of ancestral animals that upon arrival shed their animal appearance and became human.

The first documented contact with Westerners was in 1792 during the expedition led by English officer Captain George Vancouver, and was soon followed by colonies of Europeans settling on Canada's West Coast. 

As was often the way, with settlers came disease and the Kwakwaka’wakw population dropped by up to 75% between 1830 and 1880. Their distinctive ideas about wealth — that status came not from how much you owned but how much you were able to give away — came to the particular attention of the US anthropologist Franz Boas, who wrote extensively on their elaborate gift-giving ceremonies known as the potlach. 

The ceremonial practice was also a particular target of Christian missionaries who saw it as a major obstacle to their "civilizing" mission, and the Canadian government banned the practice in 1885 —although the act was soon amended, proving impossible to enforce.

This photograph of the ceremonial dress and masks of the Kwakwaka'wakw was the creation of American photographer and ethnologist Edward Curtis (1868–1952), famous for his work with First Nations and Native American people. 

Part of a project funded by banking magnate J.P. Morgan, these photographs are from the collection held at the Library of Congress and contain many images not published in Curtis' enormous twenty-volume The North American Indian. In 2015, Taschen produced their epic 768-page The North American Indian: The Complete Portfolios, which gathers Curtis’ entire American Indian portfolio into one publication.

SEAGULLS: T'SIK'WI

A gull cries in protest at not getting his share of a meal

Gulls, or colloquially seagulls, are seabirds of the family Laridae in the suborder Lari. 

The Laridae are known from not-yet-published fossil evidence from the Early Oligocene — 30–33 million years ago. 

Three gull-like species were described by Alphonse Milne-Edwards from the early Miocene of Saint-Gérand-le-Puy, France. 

Another fossil gull from the Middle to Late Miocene of Cherry County, Nebraska, USA, has been placed in the prehistoric genus Gaviota. 

These fossil gulls, along with undescribed Early Oligocene fossils are all tentatively assigned to the modern genus Larus. Among those of them that have been confirmed as gulls, Milne-Edwards' "Larus" elegans and "L." totanoides from the Late Oligocene/Early Miocene of southeast France have since been separated in Laricola.

Gulls are most closely related to the terns in the family Sternidae and only distantly related to auks, skimmers and distantly to waders. 

A historical name for gulls is mews, which is cognate with the German möwe, Danish måge, Swedish mås, Dutch meeuw, Norwegian måke/måse and French mouette. We still see mews blended into the lexicon of some regional dialects.

In the Kwak̓wala language of the Kwakiutl or Kwakwaka'wakw, speakers of Kwak'wala, of the Pacific Northwest and my family, gulls are known as t̕sik̕wi. Most folk refer to gulls from any number of species as seagulls. This name is a local custom and does not exist in the scientific literature for their official naming. Even so, it is highly probable that it was the name you learned for them growing up.

If you have been to a coastal area nearly everywhere on the planet, you have likely encountered gulls. They are the elegantly plumed but rather noisy bunch on any beach. You will recognize them both by their size and colouring. 

Gulls are typically medium to large birds, usually grey or white, often with black markings on the head or wings. They typically have harsh shrill cries and long, yellow, curved bills. Their webbed feet are perfect for navigating the uneven landscape of the foreshore when they take most of their meals. 

Most gulls are ground-nesting carnivores that take live food or scavenge opportunistically, particularly the Larus species. Live food often includes crab, clams (which they pick up, fly high and drop to crack open), fish and small birds. Gulls have unhinging jaws which allow them to consume large prey which they do with gusto. 

Their preference is to generally live along the bountiful coastal regions where they can find food with relative ease. Some prefer to live more inland and all rarely venture far out to sea, except for the kittiwakes. 

The larger species take up to four years to attain full adult plumage, but two years is typical for small gulls. Large white-headed gulls are typically long-lived birds, with a maximum age of 49 years recorded for the herring gull.

Gulls nest in large, densely packed, noisy colonies. They lay two or three speckled eggs in nests composed of vegetation. The young are precocial, born with dark mottled down and mobile upon hatching. Gulls are resourceful, inquisitive, and intelligent, the larger species in particular, demonstrating complex methods of communication and a highly developed social structure. Many gull colonies display mobbing behaviour, attacking and harassing predators and other intruders. 

Certain species have exhibited tool-use behaviour, such as the herring gull, using pieces of bread as bait with which to catch goldfish. Many species of gulls have learned to coexist successfully with humans and have thrived in human habitats. Others rely on kleptoparasitism to get their food. Gulls have been observed preying on live whales, landing on the whale as it surfaces to peck out pieces of flesh. They are keen, clever and always hungry.

HUMMINGBIRD: K'WA'AK'WAMT'A

Irridescent, quick of wing and oh, so beautiful — the wee lovers of nectar who grace our blossoms are hummingbirds.

In the Kwak̓wala language of the Kwakiutl or Kwakwaka'wakw, speakers of Kwak'wala, of the Pacific Northwest, hummingbirds are known as k̕wa̱'ak̕wa̱mt̕a.

AMMONITE TIME KEEPERS

Argonauticeras besairei, José Juárez Ruiz

An exceptional example of the fractal building of an ammonite septum, in this clytoceratid Argonauticeras besairei from the awesome José Juárez Ruiz.

Ammonites were predatory, squidlike creatures that lived inside coil-shaped shells.

Like other cephalopods, ammonites had sharp, beak-like jaws inside a ring of squid-like tentacles that extended from their shells. 

They used these tentacles to snare prey, — plankton, vegetation, fish and crustaceans — similar to the way a squid or octopus hunt today.

Catching a fish with your hands is no easy feat, as I am sure you know. But the Ammonites were skilled and successful hunters. They caught their prey while swimming and floating in the water column. 

Within their shells, they had a number of chambers, called septa, filled with gas or fluid that were interconnected by a wee air tube. By pushing air in or out, they were able to control their buoyancy in the water column.

They lived in the last chamber of their shells, continuously building new shell material as they grew. As each new chamber was added, the squid-like body of the ammonite would move down to occupy the final outside chamber.

They were a group of extinct marine mollusc animals in the subclass Ammonoidea of the class Cephalopoda. 

These molluscs, commonly referred to as ammonites, are more closely related to living coleoids — octopuses, squid, and cuttlefish) than they are to shelled nautiloids such as the living Nautilus species.

The Ammonoidea can be divided into six orders:

• Agoniatitida, Lower Devonian - Middle Devonian
• Clymeniida, Upper Devonian
• Goniatitida, Middle Devonian - Upper Permian
• Prolecanitida, Upper Devonian - Upper Triassic
• Ceratitida, Upper Permian - Upper Triassic
• Ammonitida, Lower Jurassic - Upper Cretaceous

Ammonites have intricate and complex patterns on their shells called sutures. The suture patterns differ across species and tell us what time period the ammonite is from. If they are geometric with numerous undivided lobes and saddles and eight lobes around the conch, we refer to their pattern as goniatitic, a characteristic of Paleozoic ammonites.

If they are ceratitic with lobes that have subdivided tips; giving them a saw-toothed appearance and rounded undivided saddles, they are likely Triassic. For some lovely Triassic ammonites, take a look at the specimens that come out of Hallstatt, Austria and from the outcrops in the Humboldt Mountains of Nevada.

Hoplites bennettiana (Sowby, 1826) Christophe Marot

If they have lobes and saddles that are fluted, with rounded subdivisions instead of saw-toothed, they are likely Jurassic or Cretaceous. If you'd like to see a particularly beautiful Lower Jurassic ammonite, take a peek at Apodoceras. Wonderful ridging in that species.

One of my favourite Cretaceous ammonites is the ammonite, Hoplites bennettiana (Sowby, 1826). This beauty is from Albian deposits near Carrière de Courcelles, Villemoyenne, near la région de Troyes (Aube) Champagne in northeastern France.

At the time that this fellow was swimming in our oceans, ankylosaurs were strolling about Mongolia and stomping through the foliage in Utah, Kansas and Texas. Bony fish were swimming over what would become the strata making up Canada, the Czech Republic and Australia. Cartilaginous fish were prowling the western interior seaway of North America and a strange extinct herbivorous mammal, Eobaatar, was snuffling through Mongolia, Spain and England.

In some classifications, these are left as suborders, included in only three orders: Goniatitida, Ceratitida, and Ammonitida. Once you get to know them, ammonites in their various shapes and suturing patterns make it much easier to date an ammonite and the rock formation where it is found.

Ammonites first appeared about 240 million years ago, though they descended from straight-shelled cephalopods called bacrites that date back to the Devonian, about 415 million years ago, and the last species vanished in the Cretaceous–Paleogene extinction event.

They were prolific breeders that evolved rapidly. If you could cast a fishing line into our ancient seas, it is likely that you would hook an ammonite, not a fish. They were prolific back in the day, living (and sometimes dying) in schools in oceans around the globe. We find ammonite fossils (and plenty of them) in sedimentary rock from all over the world.

In some cases, we find rock beds where we can see evidence of a new species that evolved, lived and died out in such a short time span that we can walk through time, following the course of evolution using ammonites as a window into the past.

For this reason, they make excellent index fossils. An index fossil is a species that allows us to link a particular rock formation, layered in time with a particular species or genus found there. 

Generally, deeper is older, so we use the sedimentary layers of rock to match up to specific geologic time periods, rather like the way we use tree rings to date trees. A handy way to compare fossils and date strata across the globe.

FRANZ BOAS WITH THE HUNT FAMILY, FORT RUPERT 1894

 

DRAGONFLIES: ODONATA

Dragonflies, from the order Odonata, have been around for over 250 million years. The most conspicuous difference in their evolution over time is the steady shrinking of their wingspan from well over two and a half feet down to a few inches.

Voracious predators, today they dine on bees, wasps, butterflies and avoid the attentions of birds and wee lizards -- but back in the day, they had a much larger selection of meals within their grasp.

Time has turned the tables. Small lizards and birds who today choose dragonflies as a tasty snack used to be their preferred prey.

LOWER CRETACEOUS ACANTHOHOPLITES

A very pleasing example of the Ammonite Acanthohoplites bigoureti (Seunes, 1887). Lower Cretaceous, Upper Aptian, from a riverbed concretion, Kurdzhips River, North Caucasus Mountains, Republic of Adygea, Russia. 

Geologically, the Caucasus Mountains belong to a system that extends from southeastern Europe into Asia and is considered a border between them. The Greater Caucasus Mountains are mainly composed of Cretaceous and Jurassic rocks with the Paleozoic and Precambrian rocks in the higher regions. 

Some volcanic formations are found throughout the range. On the other hand, the Lesser Caucasus Mountains are formed predominantly of the Paleogene rocks with a much smaller portion of the Jurassic and Cretaceous rocks. 

The evolution of the Caucasus began from the Late Triassic to the Late Jurassic during the Cimmerian orogeny at the active margin of the Tethys Ocean while the uplift of the Greater Caucasus is dated to the Miocene during the Alpine orogeny.

The Caucasus Mountains formed largely as the result of a tectonic plate collision between the Arabian plate moving northwards with respect to the Eurasian plate. As the Tethys Sea was closed and the Arabian Plate collided with the Iranian Plate and was pushed against it and with the clockwise movement of the Eurasian Plate towards the Iranian Plate and their final collision, the Iranian Plate was pressed against the Eurasian Plate. 

As this happened, the entire rocks that had been deposited in this basin from the Jurassic to the Miocene were folded to form the Greater Caucasus Mountains. This collision also caused the uplift and the Cenozoic volcanic activity in the Lesser Caucasus Mountains.

The preservation of this Russian specimen is outstanding. Acanthohoplites bigoureti are also found in Madagascar, Mozambique, in the Rhone-Alps of France and the Western High Atlas Mountains and near Marrakech in Morocco. This specimen measures 55mm and is in the collection of the deeply awesome Emil Black.

HALL OF GIANTS NEW MEXICO

Carlsbad Caverns National Park is in the Chihuahuan Desert of southern New Mexico. 

It features more than 100 caves. The Natural Entrance is a path into the namesake Carlsbad Cavern. Stalactites cling to the roof of the Big Room, a huge underground chamber in the cavern. Walnut Canyon Desert Loop is a drive with desert views. 

Rattlesnake Springs, a desert wetland, attracts reptiles and hundreds of bird species. If you find yourself down in New Mexico it is well worth a visit. 

Definitely bring your camera and some hiking boots with good ankle support and grip for the slippery rock you will need to traverse to explore these beauties in all their glory.

CARNOTAURUS SASTREI

Carnotaurus sastrei, a genus of large theropod dinosaur that roamed, Argentina, South America during the Late Cretaceous period, 72 to 69.9 million years ago.

This fellow (or at least his skull) is on display at the Natural History Museum in Madrid, Spain. For now, he is the only known genus of this species of bipedal predator.

The skull is quite unusual. Initially, it has a very marine reptile feel (but make no mistake this guy is clearly a terrestrial theropod). Once you look closer you see his bull-like horns (from whence he gets his name) that imply battle between rivals for the best meal, sexual partner and to be the one who leads the herd.

I'll be interested to see his cousins once more specimens of the genus are unearthed.

OLD HABITS IN CORDOBA SPAIN

Nuns stepping out from the palace, Cordoba, Spain

A group of nuns stepping out in Cordoba, Spain. The nuns earn their living selling sweets and confections using recipes handed down from the Romans and Moors. Many convents are closing because they have fewer nuns so this art may one day be lost.

The procedure for buying the sweets is archaic but charming. You enter the convent into a very small room with a lazy Susan installed on the wall. 

While we did see some nuns in the street, many do not leave the cloister or appear in public. You never see the nun with whom you do the transaction since these are cloistered nuns who avoid direct contact with the public.

On the wall beside the lazy Susan will be a price list. You look it over and decide which sweets you want to buy. Then you ring a buzzer on the wall. After a while, you will hear the voice of a nun greet you and ask you what you want to purchase. 

You share your order and after a few minutes the lazy Susan will turn and you will find your order on it. You then put your money on the lazy Susan and turn it so that the nun can get it. If there is change, the nun puts it on the lazy Susan and you then can get your change.

SHARKS: ELASMOBRANCH FISH

Sharks are a group of elasmobranch fish characterized by a cartilaginous skeleton, five to seven-gill slits on the sides of the head, and pectoral fins that are not fused to the head. 

Modern sharks are classified within the clade Selachimorpha and are the sister group to the rays.

While we often fear them — yes, they can eat you — they should fear us as we dine on them with shocking regularity. In lieu of Shark Fin Soup, a better choice would be investing money and time into their conservation.

40 DEGREES OF LATITUDE: THE ROCKIES

Images of darkened valleys, golden late summer light, icy-blue glaciers, white caps on an endless Pacific, small, hardy, yet perfect alpine flowers, spring to mind and each carries a small element but doesn't quite capture it. Heck, even our dog parks are ruggedly beautiful and by the sheer number of visits, would certainly define a large part of my west coast experience.

But the niggling thought is still there. Is there one a single element I could name that epitomizes this vast, diverse landscape? Sea to Sky, lakes to mountains, I've kayaked, hiked, sailed and lovingly explored a great deal of it. Through 40 degrees of latitude, from Yukon to Mexico, the Rocky Mountains are North America's geographic backbone.

This is the Great Continental Divide, where the interminable flatness of the interior collides with the Western Cordillera, a major mountain system of the world. From the highest ridges of the Rockies, the rivers flow to opposite corners of the land, north to the Beaufort Sea, south to the Gulf of Mexico, east to Hudson Bay and west to the Pacific.

KWAS'KWAS: OUR BEAUTIFUL BLUE JAYS

If you live in North American, there is a high probability that you have seen or heard the bird song of the Blue jay, Cyanocitta cristata (Linnaeus, 1758).

Blue Jays are in the family Corvidae — along with crows, ravens, rooks, magpies and jackdaws. They belong to a lineage of birds first seen in the Miocene — 25 million years ago. 

These beautifully plumed, blue, black and white birds can be found across southern Canada down to Florida. The distinctive blue you see in their feathers is a trick of the light. Their pigment, melanin, is actually a rather dull brown. The blue you see is caused by scattering light through modified cells on the surface of the feather as wee barbs.

Blue jays like to dine on nuts, seeds, suet, arthropods and some small vertebrates. 

If you are attempting to lure them to your yard with a bird feeder, they prefer those mounted on trays or posts versus hanging feeders. They will eat most anything you have on offer but sunflower seeds and peanuts are their favourites. 

They have a fondness for acorns and have been credited with helping expand the range of oak trees as the ice melted after the last glacial period.  

Their Binomial name, Cyanocitta cristata means, crested, blue chattering bird. I might have amended that to something less flattering, working in a Latin word or two for shrieks and screams — voce et gemitu or ululo et quiritor. While their plumage is a visual feast, their bird chatter leaves something to be desired. 

In the Kwak̓wala language of the Kwakiutl or Kwakwaka'wakw, speakers of Kwak'wala, of the Pacific Northwest and my family, a Blue Jay is known as kwa̱skwa̱s. 

The Kwak’wala word for blue is dzasa and cry is ḵ̕was'id. For interest, the word for bird song in Kwak'wala is t̕sa̱sḵwana. Both their songs and cries are quite helpful if you are an animal living nearby and concerned about predators. 

FOSSIL FIELD TRIP VIA JET RANGER

AMMONITES OF THE ARNIOCERAS BEDS

Ammonites (and two gastropods) from the Arnioceras beds near Last Creek in the Canadian Rocky Mountains. The fossils found here are from the Lower Jurassic, Lower Sinemurian, Little Paradise Member of the Last Creek formation. This site is part of the research area for Dr. Howard Tipper, GSC (who is hugely missed) and Dr. Louise Longridge, University of British Columbia.

Several ammonites species can be found here including Arnioceras semicostatum & Arnioceras miserable. The two gastropods you see in the central block have yet to be identified to species. Here's hoping a nice grad student takes an interest. The rare but lovely gastros from this area would make an excellent thesis. Perhaps comparing their distribution to their counterparts in Europe.

CRETACEOUS BONE BEDS

Einiosaurus procurvicornis was a horned dinosaur that roamed North America 74 million years ago. We find their bones in mass bone beds in Cretaceous outcrops of Montana and the Blackfeet Nation. The fossils have been recovered from rich bonebeds, largely consisting of only Einiosaurus fossils. Bonebeds with only one species are called monospecific bonebeds. But why do they occur? ⁣

⁣The most commonly suggested reason is that a herd of animals was suddenly killed by a natural disaster, like a volcanic eruption or flood. 

Their bodies were buried and remained in proximity to each other as they preserved, and today excavations uncover the remains of the unfortunate herd. Multiple other monospecific bonebeds have been found for other species of horned dinosaurs, such as Achelousaurus, causing researchers to suggest some groups of horned dinosaurs did exhibit herding behaviour— and that sometimes they met sudden unfortunate ends. But is sudden mass death from a natural disaster the only reason for monospecific bonebeds? ⁣

⁣Researchers say no. While the monospecific nature is still largely argued to represent herding in many cases, natural disaster is not always the cause of death. Sometimes large numbers of animals die from disease or starvation. Their carcasses could later be pushed together and buried by an event like a mudflow unrelated to their deaths. Their bones could also sit on the surface for years before an event that buries them. ⁣

⁣To understand the cause of a bonebed, researchers look at the bones themselves and the sediment that surrounds them. Bonebeds can tell us a lot about how these animals were living— but there is a lot to be learned from trying to figure out how they died, too. ⁣

DINOSAUR TRACKWAY

 

MIGHTY EAGLE: KWIKW (KW-EE-KW)

Bald Eagle / Kwikw / Haliaeetus leucocephalus

A mighty Bald Eagle sitting with wings spread looks to be controlling the weather with his will as much as being subject to it. This fellow has just taken a dip for his evening meal and is drying his feathers in the wind. 

As you can imagine, waterlogged feathers make flight difficult. Their wings are built for graceful soaring and gliding on updrafts of warm air called thermals. 

Their long feathers are slotted, easily separating so air flows smoothly and giving them the added benefit of soaring at slower speeds. 

As well as his wings, this fellow is also drying off his white head feathers. A bald eagle's white head can make it look bald from a distance but that is not where the name comes from. It is from the old English word balde, meaning white.

In the Kwak'wala language of the Kwakiutl First Nations of the Pacific Northwest — or Kwakwaka'wakw, speakers of Kwak'wala — an eagle is known as kwikw (kw-ee-kw) and an eagle's nest is called a kwigwat̕si. 

Should you encounter an eagle and wish to greet them in Kwak'wala, you would just say yo. Yup, just yo. They would like your yo hello better if you offered them some fresh fish. They dine on all sorts of small mammals, fish and birds but are especially fond of pink salmon or ha̱nu'n (han-oon).

These living dinosaurs are a true homage to their lineage. They soar our skies with effortless grace. Agile, violent and beautiful, these highly specialized predators can catch falling prey mid-flight and dive-bomb into rivers to snag delicious salmon. 

Their beauty and agility are millions of years in the making. From their skeletal structure to their blood cells, today’s birds share a surprising evolutionary foundation with reptiles. 

Between 144 million and 66 million years ago, during the Mesozoic era, we see the first birds evolve. Eventually, tens of millions of years ago, an ancient group of birds called kites developed. Like today’s bald eagle, early kites are thought to have scavenged and hunted fish.

About 36 million years ago, the first eagles descended from kites, their smaller cousins. First to appear were the early sea eagles, which — like kites — continued to prey on fish and whose feet were free of feathers, along with booted eagles, which had feathers below the knee. Fossils of Bald Eagles are very rare and date to the late Pleistocene. Eagles are known from the early Pleistocene of Florida, but they are extinct species not closely related to the bald eagle.

Like the kites, bald eagles have featherless feet, but they also developed a range of other impressive adaptations that help them hunt fish and fowl in a watery environment. Each foot has four powerful toes with sharp talons. Tiny projections on the bottom of their feet called “spicules” help bald eagles grasp their prey. A bald eagle also has serrations on the roof of its mouth that help it hold slippery fish, and incredibly, the black pigment in its wing feathers strengthens them against breakage when they dive head first into water.

Obviously, there is much more than their striking white heads that sets these iconic raptors apart from the crowd. Their incredible physiology, built for life near the water, is literally millions of years in the making.

SAUROPTERYGIANS

The sauropterygians are a group of diverse extinct aquatic marine reptiles that developed from terrestrial ancestors soon after the end Permian extinction. We see their earliest rellies about 245 million years ago, during the Triassic.

Their oldest relatives were small, semi-aquatic reptiles with four limbs that were adapted for paddling around in shallow water. By the end of the Triassic, they had grown to much larger animals fully adapted to a life at sea and were incapable of coming to shore.

Throughout the Jurassic and the Cretaceous developed a diverse range of body plans adapted for a life in the water. They went extinct at the end of the Cretaceous along with the dinosaurs.

The best known of the sauropterygians are the long neck Plesiosaurs but this taxon includes a whole host of other interesting Mesozoic marine reptiles. then flourished during the Mesozoic.

Sauropterygians are united by a radical adaptation of their pectoral girdle, designed to support powerful flipper strokes. While Tyrannosaurs ruled the land, and flying reptiles ruled the skies, the mighty Mosasaurs dominated the seas. They were late to the aquatic party, being the last clade to evolve.

BRITISH COLUMBIA'S GREAT BEARS

Hiking in BC, both grizzly and black bear sightings are common. Nearly half the world's population, some 25,000 grizzlies, roam the Canadian wilderness. This photo of Edward (yes, we named him) was taken off the west coast of Vancouver Island by Larissa Harding of Great Bear Nature Tours.

Both bear families descend from a common ancestor, Ursavus, a bear-dog the size of a raccoon who lived more than 20 million years ago. Seems an implausible lineage given the size of their very large descendents.

An average Grizzly weighs in around 800 lbs (363 kg), but a recent find in Alaska tops the charts at 1600 lbs (726 kg). This mighty beast stood 12' 6' high at the shoulder, 14' to the top of his head. It is one of the largest grizzly bears ever recorded. This past month this king of the forest was seen once again in the Washington Cascades -- the first sighting in 50 years.

TORVOSAURUS TANNERI

The genus Torvosaurus includes a unique species of megalosaurid therapod dinosaur.

This fellow is from the Morrison Formation, western United States but his kind spread widely and fossil specimens of the same species have been found in the Lourinha Formation near Lisbon, Portugal. He is currently on display at the Museo Nacional De Ciencias Naturales in Madrid, Spain.

Torvosaurus were one of the largest and most robust carnivores of the Jurassic. These "savage lizards" were true to their name. Skilled hunters, who could grow from 9 to ll meters long, weigh over 2 tons, were bipedal with powerful dentition and strong claws on their forelegs, they ruled the Upper Jurassic.

While currently speculative, there seems to be a high likelihood that these bad boys hunted and dined upon the big sauropods of their time.

BOWRON LAKE CIRCUIT

PACIFIC NORTHWEST TRAILS

One of the most beautiful in the Pacific Northwest is the Olympic Peninsula from Port Angeles to Neah Bay.

This stretch of coastline is home to the Clallam Formation, a thick, mainly marine sequence of sandstones and siltstones that line the northwestern margin of western Washington. These beachfront exposures offer plentiful fossils for those keen to make the trek.

The beautifully preserved clams, scallops and gastropods found here are mostly shallow-water marine from the late Eocene to Miocene. Time, tide and weather permitting, a site well worth visiting is the south flank of a syncline at Slip Point, near Clallam Bay. Head to the most Northwestern tip of the lower 48, visiting Cape Flattery on the Makah Reservation located 75 miles NW of PA on Hwy 112. Cape Flattery is located approx 7 miles from Neah Bay. The newly constructed wooden walkway takes you to some of the most gorgeous, rugged and wild scenery on the Pacific Coast.

Be sure to take time to explore the internationally known Makah Museum. The museum is open every day during the summer months and closed Mondays and Tuesdays from Sept. 16 through May 31. The hours are 10AM-5PM. The Makah Museum is the nation's sole repository for archaeological discoveries at the Makah Coastal village of Ozette. The centuries-old village was located 15 miles south of present-day Neah Bay. Ozette served the Makah people as a year-around home well into the 20th century.

In 1970 tidal erosion exposed a group of 500-year-old Ozette homes that have been perfectly preserved in an ancient mudslide. The thousands of artifacts subsequently discovered have helped recreate Makahs' rich and exciting history as whalers, fishermen, hunters, gatherers, craftspeople, basket weavers, and warriors. Lake Ozette is located off of Hwy 112 on the Hoko-Ozette Road and follows the road 21 miles to the Ozette Ranger Station.

Three miles of planked trail leads the hiker to Sand Point, one of the most beautiful and primitive beaches on the coast. Continuing north along the beach you will find dozens of Indian petroglyphs at Wedding Rocks, ask for the interpretive handout at the ranger station. The northern point of this 9-mile triangular trail is Cape Alava, with a rocky shore and reefs to explore at low tide. Cape Alava is also the site of an ancient Makah village. The site is now closed and marked with a small sign. Be sure to check a tide table and carry the 10 essentials - and lots of film as seals, deer, eagles and perhaps osprey, otters and whales may be there, rain or shine! Hike north to Cape Alava along the beach to keep the ocean breeze at your back, and avoid Vibram-soled shoes as the cedar plank walkway can be slick!

Salt Creek County Park located on the Strait of Juan de Fuca west of Port Angeles offers fascinating tidal pools, (ask your hosts regarding tide tables). The Dungeness Spit and Wildlife Refuge offers great beach hiking and wildlife. The Olympic Game Farm in Sequim is great for children of all ages. Ediz Hook in Port Angeles provides great views of the Olympic and Cascade mountains. Ediz Hook is part of the 5.5 miles of Waterfront Trail; perfect for jogging, walking, biking, or rollerblading.
The Elwha Valley west of Port Angeles is a beautiful drive along the rushing Elwha River. Madison Falls is an easy hike. Further up the valley beyond Lake Mills is the trailhead to the Olympic Hot Springs.

Port Townsend, known as "Washington's Victorian Seaport" is less than an hour east of Sequim. Victorian homes and commercial buildings erected during the late 1800s are still the city's trademark, along with Fort Worden State Park.

Park fee: A pass is required to enter the Olympic National Park. The fee is $10.00 per carload and is good for 7 days. It can be attained at any of the Park entrances. No pass is required during the winter months for the Elwha Valley or the Sol Duc Valley. Phone # for Olympic National Park Visitors Center in Port Angeles is 360-452-2713.

Getting there…

Directions: From Vancouver, it is a 5-6 hour drive to the Olympic Peninsula. Head South on Oak or Knight to connect up with Hwy 99 to the US border and continue South on Hwy 5, past Bellingham, take Hwy 20 to Anacortes.Head South on Hwy 20 until you get to the Keystone Jetty. Take the ferry from Keystone to Port Townsend. From Port Townsend take Hwy 20 until it connects with Hwy 101. Turn right onto Hwy 101 and head West.

You will pass through Port Angeles. This is an excellent place for you to top up your food stores and fill up with gas. Just after Port Angeles, look for a sign for Hwy 112 (towards Joyce, Neah Bay & Seiqu). Turn right and head West. It is about another 30 km from Port Angeles to Whiskey Creek. From the turn-off, it is about 10 miles to Joyce.

This little town has restaurants and gas stations. From Joyce, it is another 3 miles to the campsite at Whiskey Creek where Joe or Ronee can help direct you to your cabin or campsite.

WEE FOSSIL BEAVER

This wee skull of a Microtheriomys brevirhinus from the John Day Formation is an adorable 19 mm. Yeah, he's pretty cute!

Paleontologists Dr William Korth of Rochester Institute of Vertebrate Paleontology and Dr Joshua Samuels of John Day Fossil Beds National Monument are pretty chuffed about some new fossil finds. They have described four new genera and ten new species of prehistoric rodents that lived in what is now Oregon during the Oligocene -- 30- 22 million years ago.

The newly-discovered genera include this wee fellow, the early beaver, Microtheriomys brevirhinus, a dwarf tree squirrel, Miosciurus covensis, a primitive pocket mouse, Bursagnathus aterosseusm the birch mouse Plesiosminthus fremdi, an early relative of beavers, Allotypomys pictus along with bits and pieces of Proapeomys condoni; Apeomys whistleri; Neoadjidaumo arctozophus, Proheteromys latidens & Trogomys oregonensis.

Of these ten new species, four represent completely new genera: Allotypomys, Microtheriomys, Proapeomys, and Bursagnathus.

“This study fills some substantial gaps in our knowledge of past faunas, specifically smaller mammals,” said Dr Samuels, who is a co-author of the paper published in the Annals of Carnegie Museum. “Some of the new species are really interesting in their own right, and will ultimately help improve our understanding of the evolution of beavers and pocket mice.” The new rodents were collected through decades of collaborative work throughout the John Day Formation, Oregon.

RADIOLARIA: EXQUISITE MICROFOSSILS

Radiolarian microfossils, tiny, siliceous, single-celled organisms, make for excellent timekeepers. Think of them as the world's smallest clocks. These wee fellows have been living in the world’s oceans for over 600 million years.

Radiolarians are unicellulars, wee little things with a diameter of 0.1–0.2 mm.

They produce intricate mineral skeletons, typically with a central capsule dividing the cell into the inner and outer portions of endoplasm and ectoplasm.Their beautifully elaborate mineral skeletons are usually made of silica. We find radiolaria as zooplankton throughout the ocean and their skeletal remains make up a large part of the cover of the ocean floor as siliceous ooze.

Due to their rapid turnover of species, they represent an important diagnostic fossil from the Cambrian onwards. Because they occur in continuous and well-dated sequences of rock, they act like a yardstick, helping geologists accurately date rock from around the globe.

In the Upper Triassic rocks, which predate the Triassic / Jurassic Mass Extinction event by about 10 million years, radiolarians are preserved in hundreds of forms. Just above them, in the early Jurassic rock layers laid down about the time of the great die-offs, only a fraction of the previous number of forms are represented. The more recent Jurassic rock shows a rebound of radiolarian diversity, though of course, in different forms, a diversity which continues to flourish and expand in today’s oceans.
