2008-10-12 - British Columbia, Canada: danneggiato sito dell’Eocene (fossil site damaged) Fossil hunters run amok and the B.C. government sits idle S
Reprinted from the Vancouver Sun, Published: Friday, October 10, 2008
While my writing is referenced, I did was not contacted for the article and did not provide comment.
A fossil bed of global importance is being irreparably damaged by commercial fossil hunters operating with provincial government approval, say leading scientists.
And scientists’ letters to a series of cabinet ministers and senior bureaucrats show that although the province is finally seeking someone to monitor the site, it has been aware of the concerns for almost a decade.
The operations take place under provincial regulations.
One letter likened what’s been going on to “wrapping fish in the Dead Sea Scrolls.”
The McAbee site between Kamloops and Cache Creek is a 51-million-year-old lake bed that yields exquisitely preserved fossils from the early Eocene epoch. Scientists say it holds answers critical to our present-day understanding of how plants and animals adapt to rapid climate change.
The Eocene is known for its diversity of large and exotic mammals, among them a carnivorous ungulate. The scientific value of the McAbee site, however, is its vast array of lesser-known plant, insect, fish and bird species that flourished when the world was much warmer and palms grew in what’s now Alaska.
Tree leaves, flowers and pollen fell into the water, sank into the mud along with now-extinct insect and fish species and, layer by layer over millions of years, created a stunning fossilized record of a lost world that may hold information crucial to survival in ours.
It’s the diversity of the site that permits scientists to collect large assemblages of fossil specimens preserved in vertical layers of shale — the site’s “stratigraphy” — and enables them to study their evolution over long periods of time.
The Eocene is vital for scientific study because it was in this time that the evolutionary ancestors of many modern animals, insects and plants first appeared.
But five of Canada’s leading paleontologists have written to the provincial government protesting that the stratigraphic integrity of the site is being destroyed by the use of heavy equipment in the hunt for individual specimens prized for commercial sale.
“We are writing to you to express our concern that an important British Columbia heritage site is currently being dismantled and sold to the highest bidder,” the scientists said in a March 2, 2007 letter to Charlie Wyse, the Liberal MLA for Cariboo South.
“This important fossil locality is currently under mineral claim by fossil dealers, has been extensively worked, and is being rapidly destroyed.”
The letter, one of a number going back as far as 2002, advised the province that individual fossil specimens from the McAbee site were for sale on the Internet.
The letter was signed by James Haggart, chair of the B.C. Paleontological Alliance, Rolf Mathewes of Simon Fraser University, James Basinger at the University of Saskatchewan, David Greenwood at Brandon University and Bruce Archibald, a PhD candidate at Harvard University.
Archibald, now a post-doctoral fellow at Simon Fraser University, has done extensive research on the McAbee fossils.
He wrote again on Sept. 11, 2008, this time to Stan Hagen, minister of agriculture and lands, to inform the government that he had just visited the McAbee site.
“I was absolutely shocked to see the amount of new destruction present,” Archibald wrote. “In fact, the richest beds containing the most finely preserved and most diverse fossils are now completely destroyed, or very nearly so. It is quite clear that degradation of the site has greatly accelerated since I visited it last year before the claimholders signed the current agreement with your ministry supposedly defining their appropriate stewardship of the site.”

SALMON: RETURN TO SENDER
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 ::
:: 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.

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
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
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.

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.

Qualicum Beach: The Gem of Vancouver Island
Whether its the beach that draws you or the leisurely stroll through town, you have many options for your oceanside visit. Visit the local galleries, boutiques and cafes that make Qualicum feel like a European village or check out their famous garage sales for their many bargains.
The outdoor enthusiast will appreciate the long stretches of sandy beach, old growth forests, nearby mountains with winter skiing and mild climate for year-round golf.
A trip to Qualicum Beach is a bit like visiting a garden county in England, all hanging baskets and clipped lawns. There are many hidden treasures in the area.
You could take in the fresh air and hike the alpine trail leading to Mount Arrowsmith Lookout or follow gentle paths amongst the 850 year old Douglas Firs at MacMillan Park’s Cathedral Grove.
There are fossils to be found... though not extracted from the park at Englishman River Falls or you could explore the Crystalline interior of the Horne Lake underground caves - an intriguing side trip just west of the town of Qualicum. Those in the know travel to these moist refuges to take in the quiet and walk in wonder and shadow with the help of one of the local guides.
No trip to Qualicum Beach is complete without a trip to the Qualicum Museum.
Here you’ll see the life-time collection of Graham Beard, co-author of West Coast Fossils and Chair of the Vancouver Island Paleontological Museum Society. With his wife, Tina, a talented artist and fossil collector in her own right, he has been actively collecting fossils on Vancouver Island for over 30 years.
Getting there:
From the Departure Bay ferry terminal in Nanaimo, stay to your right and head up the hill and head north on the Island Hwy north. Take the Qualicum turn-off. The road heads straight through this picturesque little town, past quaint little coffee shops and continues to the seashore. To visit the Qualicum Museum, turn left onto Sunningdale just as you cross the railroad tracks.
The museum is at the end of the street. They have a sweet interglacial walrus found in Qualicum and a nice selection of other local fossils.
