SALMON: RETURN TO SENDER
We are all familiar with the image of salmon returning to fresh water, to the rivers of their youth, to spawn and complete their lifecycle, in fact, it is one of the staple images of British Columbia. As adults, we bring our children to witness this cycle, rushing to the banks of our local rivers to watch as the adults, keen in their fight for reproduction and survival, struggle to complete their epic journeys against currents and predators. Arriving as they do, year upon year, season upon season, it seems to us that this is how it has been since time immemorial.
But we now have evidence that migration to the sea may be a relatively recent behaviour. Fossil beds at Driftwood Canyon, near Smithers, contain large numbers of fossil salmonid remains from the Eocene age, approximately 45 million years ago. What is interesting is that the fossil beds are filled equally with both juvenile and larger adults.
If these salmon were heading off to sea in their juvenile form and returning to spawn as adults we would expect to find an abundance of larger carcasses in the lake sediments and relatively few juveniles. Given the equal numbers, we can conclude that the salmonids of the Eocene, lived out their lifecycle as a landlocked species, the way Kokanee do today.

:: Dragon in the Rocks :: The Early Years of Mary Anning ::
Dragon in the Rocks. A Story Based on the Childhood of Early Paleontologist Mary Anning
Toronto: Owl/Greey de Pencier, 1992. [32] p.ISBN 0-920775-76-4
Mary Anning (1799-1847)/biography – Paleontology/England/19th century
Looking to inspire a young mind to the wonders of our world? Consider a new picture book for young readers from Owl Press. This lovely new book shares the early years of Mary Anning - a simple tale of curiosity and determination within the wider context of an historical geological discovery.
Twelve-year-old Mary Anning had always enjoyed collecting fossils with her father, an amateur collector, who before he died, taught her the techniques of chipping and separating fossils from rocks.
Mary's father also told her of a dragon skeleton he had once seen in a cave near their home in Lyme Regis on the southern coast of England. One day the opportunity arose to visit the cave herself, and subsequently she spent many months chipping, numbering and packing up the fossil pieces of the 26-foot-long ichthyosaur skeleton, which has now been on display at the Natural History Museum in London for nearly 200 years.
Although the story ends with the visit of important scientists to her home to see her rebuilt skeleton, children may well be inspired to learn more about the interests and life of this unsung heroine and about paleontology.
Looking for more inspiration on the significant finds of other young paleontologists... look to Tumbler Ridge and the discovery by Daniel Helm of a significant dinosaur trackway that inspired a community or to Vancouver Island and the tale of paleontology in beautiful Courtenay where the Trask family found one of BC's most famous marine reptiles.

:: ARMORED BEAST :: DESMATOSUCHUS ::
A detailed description of Desmatosuchus
:: Description of new material of the aetosaur Desmatosuchus spurensis (Archosauria: Suchia) from the Chinle Formation of Arizona and a revision of the genus DesmatosuchusWilliam Parker, PaleoBios 28(1):1–40, May 12, 2008Abstract: A new specimen of Desmatosuchus from northeastern Arizona (MNA V9300) preserves almost the entire vertebral column, the pelvis, and the majority of the armor carapace, allowing for an unprecedented detailed description of the taxon.
Articulation and reconstruction of the armor carapace demonstrates that previous reconstructions of Desmatosuchus are erroneous in the orientation and position of the lateral armor. Lateral plates of the anterior dorsal region possess low rounded knobs instead of developed spines.
The dorsal flange of the lateral plates of the dorsal region is longer than the lateral or ventral flange making the carapace transversely wider than previously thought. As a result, previous reconstructions articulate the lateral armor not only backwards but also on the wrong sides of the body. Posterior presacral vertebrae are extremely robust and possess fused ribs and the last presacral vertebra has been fused to the sacrum, a character that may be taxonomically useful.
A prefrontal bone is also present in Desmatosuchus, contrary to previous descriptions. Reinvestigation of the genus Desmatosuchus suggests that there are only two valid species, D. spurensis and D. smalli. The lectotype of Episcoposaurus haplocerus is referable to Desmatosuchus but indeterminate at the species level, and therefore represents a nomen dubium.
Accordingly, D. spurensis is reinstated as the type species of Desmatosuchus and the new Arizona specimen is assigned to this taxon. Acaenasuchus geoffreyi, a purported juvenile form of Desmatosuchus, is not referable to Desmatosuchus.

A Wee Beasty for Betsy
I was delighted to hear that one of our long lost friends and renowned paleontologist, Betsy Nicholls would be honored with a new namesake out of Alberta - a mighty marine hunter from our Cretaceous Seas... This newly described plesiosaur, Nichollsia borealis, has been named for the late Elizabeth (Betsy) Nicholls, a renowned paleontologist from the University of Calgary. Betsy holds a special place in the hearts of the paleo community, particularly those in Alberta and British Columbia who had the opportunity to work with her over the years.
She greatly broadened our understanding of the large marine reptiles who swam our ancient seas in describing one of the largest marine reptiles ever to be found. Alberta is the home of the dinosaurs, but it was Betsy’s work that opened up our eyes to the great marine beasties that continue to be unearthed over much of northern British Columbia…

Sunshine & Rain: Bowron's Lanezi and Sandy Lakes
Like most mountainous areas, Bowron makes its own weather system and it appears you get everything in a 24-hour period. In fact, whatever weather you are enjoying seems to change 40 minutes later; good for rain, bad for sun. Wisps of cloud that seemed light and airy only hours early have become dark.
Careful to hug the shore in our kayaks, we are ready for a quick escape from lightening as thundershowers break. Paddling in the rain, I notice bits of mica in the water, playing in the light and the rock change here to greywacke, argillite, phyllite and schist. Past Lanezi, we continue onto Sandy Lake, where old growth cedars line the south-facing slopes to our left and grey limestone, shale and dolostone line the shore. Mottled in with the rock, we sneak up on very convincing stumps posing as large mammals.
Picking up the Cariboo River again, we follow it as it flows into Babcock Lake, an area edged with Lower Cambrian limestone, shale and argillite. At the time these rocks were laid down, the Earth was seeing our earliest relatives, the first chordates entering the geologic scene.

THE SCIENCE OF LOVE AND INFIDELITY
Big chin. Big cheater.As Valentine’s Day approaches, both mating and chocolate get on the brain. If you have not already chosen your new love, researchers suggest you stay away from those with big chins as they have a tendency to cheat. Researchers from four universities across the US and Canada prodded into the sexual habits of chinny and relatively chin-less females to determine these resultts.
Kidding? No, they’ve published in the journal Personality And Individual Differences, so it must be true. Larger chins, especially on adult females, are associated with the male growth hormone testosterone and too much of that bad boy can lead to messing around. It seems on an unconscientious level men sense this trend and are biased against a more masculine chin.
"The findings are important in demonstrating that perceptions of women as desirable and trustworthy long-term mates can be reliably gleaned by men from viewing only the women's facial features.
"Results suggest that information about women's sexual unrestrictedness, which is related to their risk of infidelity, can potentially be conveyed by the masculinity of women's faces."
Hogwash you say? Perhaps you are already hooked up with said chin-cheater? Well, they may cheat, but you may also have found s sexual goldmine. Women with larger chins are also more sexually assertive and perhaps better in bed.
While the study only looked at the chins of the female of our species. Friends and neighbors also speculate on the tendencies of our males. Is Leno a complete dog? And what of the chin of our own Brian Mulroney?
Bring on the chocolate and the chins I say. It's Valentine's Day!

ORCA MAX'INUX
Orca, Black Fish or Killer Whale — these toothed whales in the oceanic dolphin family are one of the most recognized species in the world.
These large marine mammals are easily distinguished by their black-and-white colouration, large dorsal fin and a sleek, streamlined body. You can often get a peek at their top fin and just enough of their distinctive white eye patch to id
Their genus name Orcinus means "of the kingdom of the dead."
In the Kwak̓wala language of the Kwakiutl or Kwakwaka'wakw, speakers of Kwak'wala, of the Pacific Northwest, orca or killer whales are known as max̱'inux̱.

CARCHARDONTOSAURUS GOES EXTINCT TWICE
Carcharodontosaurus iguidensis from the Cenomanian of Nigeria and published in this months issue Journal of Vertebrate Paleontology. This fellow almost had the misfortune of going extinct twice!
Tooth fragments collected by Charles Depéret and J. Savornin in 1927 were misplaced before this meat-eater could ever be described and when additional material was collected in Egypt in the 1930’s it also came to an unfortunate end. Sent to German paleontologists in Munich to describe, the fossils were lost in the rubble as Allied Forces bombed the building in which they were housed during WW II.
But the rocky history and luck of Carcharodontosaurus iguidensis improved when paleontologist Paul Sereno found cranial material on a Moroccan dig in 1996. That find combined with material collected the following year in Nigeria were examined by Sereno and Steve Brusatte, a paleobiologist at the University of Bristol in England, and Paul Sereno and determined to be a new species, not C. saharicus as originally thought.
The massive skull, neck and bone fragments belonged to Carcharodontosaurus iguidensis, one of the largest dinosaurs ever found. Carcharodontosaurus differs from C. saharicus, his smaller Saharan coursin, both in the maxilla and braincase. Carcharodontosaurus iguidensis walked upright and was a massive beast, weighing in at an impressive 3.2 tons.
Extending upwards of 14 meters (44 ft), nearly as long as Tyrannosaurs, alive today they could easily peer through a second story window - a menacing thought as they were well-equipped hunters with sizable teeth.The climate was much warmer when Carcharodontosaurus iguidensis and C. saharicus roamed the Earth and the seas much higher. Beyond geographic distance, the raised sea level may have been what set these therapods apart. Shallow seas separated what is now Morocco and Nigeria and this separation may have prompted the development of the unique characteristics define the two species.. Perhaps more abundant prey and favorable conditions allowed Carcharodontosaurus iguidensis to grow to their huge size while C. saharicus remained a smallish 1.6 meters (5.2 ft).
While not a reptile, C. saharicus has been compared with modern Crocodylia, another group who first appeared in the Cretaceous, as they share similar inner ear anatomy and cerebrum size relative to total brain. Like many therapods prior to the 1930’s, the African species were originally misgrouped into the genus Megalosaurus. Paleontologist Ernst Stromer von Reichenbach corrected this error.
After taking a closer look at their anatomy, particularly their dentition, he renamed them Carcharodontosaurus in 1931 citeing their "mainly Carcharodon-like teeth", which were "not recurved, almost bilaterally symmetrical but with convex edges” The Carcharodontosaurids were a group of gigantic carnivorous carcharodontosaurid dinosaurs that lived 98 to 93 million years ago.
Carcharodontosaurus means 'shark lizard', after the shark genus Carcharodon, an apt handle as they were ominous killers with enormous jaws and long, serrated teeth, some as long as eight inches.

Fossil Field Trip to the Olympic Peninsula
One of the most beautiful drives in the Pacific Northwest is the coastline along the Olympic Peninsula from Port Angeles to Neah Bay. This stretch of coastline is also home to the Clallam Formation, a thick, mainly marine sequence of sandstones and siltstones that line the northwestern margin of the Olympic Peninsula, western Washington. The sequence offers plentiful fossils for those keen to make the trek.
The beautifully preserved clams, scallops and gastropods. The fossils found at Clallam are mostly shallow-water 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 BayGetting 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 kms 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 our campsite at Whiskey Creek where Joe or Ronee can help direct you to your cabin or campsite.
Where to stay…
We will be staying at the Whiskey Creek Campsite, 1385 Whiskey Creek Beach Road, Port Angeles, WA, 98363, Tel: (360) 928-3489. Whiskey Creek is a saltwater beach on the Strait of Juan de Fuca, 19 miles west of Port Angeles off Highway 112 – 3 miles west of Joyce. The owners are Joe and Ronee, P.O. Box 130, Joyce, WA, 98343.The Whiskey Creek Campsite is open from May 1st to Oct 1st for tenting and year-round for their cabins. Cabins range in price from $70 - $80US/night and sleep 4. They are all right on the ocean except for one, which is set back a ways. Several of the cabins have in-suite washroom, incl. Showers, kitchenette & stoves.
Codfish Cottage is all propane and has an elevated Queen bed and a hide-a-bed. The higher priced cabins are full propane and the cheaper ones are wood heat. They book up early, so call early.For camping, each site holds 4 and is $15.00/night and an additional $2.50 for every extra person. They do not showers, electricity or phones. There is a general store in Joyce, just 3 miles East, that sells food, ice, propane, firewood, etc. The campsite is dog friendly. Dogs must be kept on a leash and all poop scooped. They charge $2.00/day.Cabins: H Jasper Inn ($70/night sleeps 4) H HH H CQ H CF*
Please note that the Lyre River Campsite closed permanently as of Sept 2003. What to bring…If anyone is joining us, they want to purchase a Washington State map. Maps are available at many of the gas stations once you cross the border. Runners or hiking boots, rubber boots, sandals, sunscreen, food and US$ for gas and ferries. You’ll also want a backpack, chisel, newspaper to wrap fossils, hammer, goggles, gloves, hat and outer wear. A notebook and pencil for field notes.

OYSTERS: TLOXTLOX
While rare today, these are British Columbia’s only native oyster. Had you been dining on their brethren in the 1800s or earlier, it would have been this species you were consuming. Middens from Port Hardy to California are built from Ostrea lurida.
These wonderful invertebrates bare their souls with every bite. Have they lived in cold water, deep beneath the sea away from the suns rays and heat? Are they the rough and tumbled beach denizens whose thick shells have formed to withstand the pounding of the sea?
Is the oyster in your mouth thin and slimy having just done the nasty spurred by the warming waters of Spring? Is this oyster a local or was it shipped to your current local and if asked would greet you with "Kon'nichiwa?" Not if the beauty on your plate is indeed Ostrea lurida.
We have been cultivating, indeed maximizing the influx of invasive species to the cold waters of the Salish Sea. But in the wild waters off the coast of British Columbia is the last natural abundant habitat of the tasty Ostrea lurida in the pristine waters of Nootka Sound. The area is home to the Nuu-chah-nulth First Nations who have consumed this species boiled or steamed for thousands of years. Here these ancient oysters not only survive but thrive — building reefs and providing habitat for crab, anemones and small marine animals.
Oysters are in the family Ostreidae — the true oysters. Their lineage evolved in the Early Triassic — 251 - 247 million years ago.
In the Kwak̓wala language of the Kwakiutl or Kwakwaka'wakw, speakers of Kwak'wala, of the Pacific Northwest, an oyster is known as t̕łox̱t̕łox̱. I am curious to learn if any of the Nuu-chah-nulth have a different word for an oyster. If you happen to know, I would be grateful to learn.
