Dinosaur Discovery GalleryTumbler Ridge, British Columbia

21 April 2015

The gallery contains displays primarily focused on interpreting regional vertebrate palaeontology including material from B.C.’s two dinosaur excavations. There are also displays on dinosaur and other vertebrate tracks and traces which make up the vast majority of the terrestrial vertebrate record of western Canada. One of British Columbia’s best-kept secrets is the massive fossil record of Triassic marine fish and reptiles from this region. Our volunteers and scientists have collaborated to bring together an impressive and rapidly growing collection of specimens for ongoing scientific research and public interpretation here in the gallery.

Our recently expanded Dinosaur Discovery Gallery contains several new and enhanced palaeontology exhibits including a full-scale re-creation of a 100 million-year-old dinosaur track environment. An interactive theatre provides several presentation options for visitors to view and learn about the pre-history of the Peace Region of British Columbia.

B.C. dinosaur path tracks heyday of prehistoric beasts

Discovered dinosaur path 115 million years old

VICTORIA – A type of dinosaur Autobahn, with a riot of ancient footprints that are likely more than 100 million years old, has been discovered in northeastern British Columbia.

Hundreds of prints from extinct carnivores and herbivores are pressed into the flat, rocky surface spanning an area the size of three Canadian football fields, indicating the site was a major dinosaur thoroughfare.

Many of the three-toed prints at the site — located near Williston Lake about 1,500 kilometres northeast of Vancouver — closely resemble the Toronto Raptors logo.

“From what I saw there is at least a score or more of trackways, so 20-plus trackways of different animals,” said paleontologist Rich McCrea.

“We’re looking at a few hundred foot prints that were exposed when I visited the site. If it keeps up that density and we are able to peel back a bit of the surface and expand it by another 1,000 square metres we’re likely to find there are thousands of foot prints.”

McCrea is the curator of the Peace Region Paleontology Research Centre in Tumbler Ridge, B.C. He believes the dinosaur path has major potential as a world-class scientific and tourism site, but said he’s concerned the B.C. government’s approach to protecting and promoting dinosaur zones is somewhat prehistoric.

“It would be one of the top sites, unquestionably,” said McCrea, who’s part of a local crowdfunding campaign to raise $190,000 to research and promote the dinosaur track site. “It already looks like it’s going to be one of the biggest sites in Canada. That also means one of the biggest sites in the world.”

He said his visits to the secret site indicate the area was a major travel zone for the Allosaurus, a Jurassic Park look-alike, 8.5-metre-long, two-legged predator with a huge head and rows of teeth.

McCrea said the area is also ripe with tracks made by the Anklosaurus [sic; Ankylosaurus], a four-legged, nine-metre-long herbivore, that weighed almost 6,000 kilograms and was known for its distinctive armour-plated head and long, club-like tail.

He estimated those tracks are between 115 million and 117 million years old.

“This was still in the dinosaurs’ heyday,” said McCrea. “It’s kind of like the middle age of dinosaurs.”

He said he wants the area protected by the B.C. government, and he’s part of a pitch to create a Peace Country dinosaur tourist zone that rivals Alberta’s Royal Tyrrell Museum at Drumheller. McCrea envisions dinosaur tours to Tumbler Ridge, Williston Lake and the Philip J. Currie Dinosaur Museum in nearby Wembley, Alta.

Last fall, Tumbler Ridge was designated as a UNESCO global geopark that recognizes geological heritage. The community converted a school into a dinosaur museum and repository for the dinosaurs fossils discovered in the area.

McCrea said he wants to see a tourist building overlooking the dinosaur trackway area at Williston Lake. A similar concept at China’s Zigong Dinosaur Museum attracts seven million people a year, he said.

Tumbler Ridge Liberal MLA Mike Bernier said he’s been trying to convince cabinet ministers that the area is an important asset and needs heritage and fossil protection policies.

“People go crazy when they see dinosaur bones and fossils. There’s something about it: the old Jurassic Park movie coming to life in your riding,” he said.

Bernier said he’s reviewing heritage protection laws from across North America and plans to submit a proposal to government this year.

B.C. Forests, Lands and Natural Resource Operations Minister Steve Thomson, whose ministry covers fossil protection, said he’s seen the Tumbler Ridge dinosaur site and has met with Bernier on strengthening the province’s fossil management.

Five years ago the government protected the world-renowned McAbee fossil beds near Cache Creek in B.C.’s Interior from professional fossil hunters and others who were mining the area for cat litter.

“We are looking at what legislative adjustments might be needed to be put in place,” said Thomson.

McCrea said Alberta and others have protected and profit from their fossil heritage, while B.C. remains behind the times.

“We’re missing out on all the opportunities, not just tourism and education, but also, how about just pride that the province itself is the custodian of all its natural resources,” he said.

Mosasaur fossil discovery by teenage boy


THis Dutch video was recorded in the natural history museum in Maastricht, the Netherlands. There, teenager Lars Barten tells about his discovery of a fossil mosasaur.

On Saturday 18 April, 14-year-old Lars Barten (14) from Rijkevoort village in Noord-Brabant province in the Netherlands, together with his father Jos, discovered a mosasaur fossil near Maastricht city in Limburg province.

That mosasaur is about 66 million years old. It was called Lars, as Lars Barten discovered it.

The discovery includes tail, flipper, backbone and finger bones.

At the natural history museum in Maastricht, there will be more research on the fossils.

Oldest known euarchontan tarsals and affinities of Paleocene Purgatorius to Primates

Significance

Purgatorius has been considered a plausible ancestor for primates since it was discovered, but this fossil mammal has been known only from teeth and jaw fragments. We attribute to Purgatorius the first (to our knowledge) nondental remains (ankle bones) which were discovered in the same ∼65-million-year-old deposits as dentitions of this putative primate. This attribution is based mainly on size and unique anatomical specializations known among living euarchontan mammals (primates, treeshrews, colugos) and fossil plesiadapiforms.

Results of phylogenetic analyses that incorporate new data from these fossils support Purgatorius as the geologically oldest known primate. These recently discovered tarsals have specialized features for mobility and provide the oldest fossil evidence that suggests arboreality played a key role in earliest primate evolution.

Abstract

Earliest Paleocene Purgatorius often is regarded as the geologically oldest primate, but it has been known only from fossilized dentitions since it was first described half a century ago. The dentition of Purgatorius is more primitive than those of all known living and fossil primates, leading some researchers to suggest that it lies near the ancestry of all other primates; however, others have questioned its affinities to primates or even to placental mammals.

Here we report the first (to our knowledge) nondental remains (tarsal bones) attributed to Purgatorius from the same earliest Paleocene deposits that have yielded numerous fossil dentitions of this poorly known mammal. Three independent phylogenetic analyses that incorporate new data from these fossils support primate affinities of Purgatorius among euarchontan mammals (primates, treeshrews, and colugos).

Astragali and calcanei attributed to Purgatorius indicate a mobile ankle typical of arboreal euarchontan mammals generally and of Paleocene and Eocene plesiadapiforms specifically and provide the earliest fossil evidence of arboreality in primates and other euarchontan mammals. Postcranial specializations for arboreality in the earliest primates likely played a key role in the evolutionary success of this mammalian radiation in the Paleocene.

Utahraptor dinosaur mass grave discovery


This video from the USA says about itself:

Gastonia vs Utahraptor– Epic!

This fight was a real fight that was recorded in bones! The Utahraptor was attacking such an armed dinosaur cause it was about to die by lack of food during a drought. And in the end both animals died, the Gastonia died by its wounds which the Utahraptor inflicted on its belly and legs. And the Gastonia died only 10 feet away after walking from the dead Utahraptor.

Fossil treasure trove in quicksand reveals ancient dinosaur death trap

By Rachel Feltman

January 7 at 9:35 AM

Reports of what looked like a human arm brought Utah state paleontologist James Kirkland to a particular sandstone hill in 2001. But it turned out that his graduate student had actually found something entirely different — a veritable mass grave of Utahraptor dinosaurs. Now they’ve found the remains of six individual dinosaurs, and there may still be more inside of the 9-ton sandstone block they’re excavating.

That “arm” was actually a foot, and the fossil bits just kept coming. The site is now the largest find ever for this particular species, which was a large, feathered cousin to the more familiar Velociraptor. It seems that these unfortunate raptors were trapped in quicksand — sand so heavy with water that it loses much of the friction between its grains. Quicksand isn’t actually the deathtrap for humans that cinema would have us believe, but for a frightened animal who couldn’t gain purchase, it might have meant suffocation or slow starvation — or simply getting stuck until a bigger predator arrived to finish the job.

Brian Switek for National Geographic reports that a plant-eating dinosaur was found at the site, too, which could mean that the raptors all died at the same time while hunting the trapped creature. That would be exciting, because despite their depiction as pack hunters in the “Jurassic Park” films, we don’t have much evidence about whether dinosaurs like these came in droves or hunted solo.

If the researchers can show that the raptors grew tangled up together as they struggled to get free, or find evidence that the same weather patterns affected their bones when they died, it would add weight to the notion that raptors liked to rumble in gangs.

You can see clips of the excavation in progress over at National Geographic.

Jurassic Park fan finds rare dinosaur remains

Published: 02 Jan 2015 06:42 GMT+01:00

A high school student from southern Sweden who discovered the remains of Sweden’s first known carnivorous dinosaur has been speaking about his discovery.

Clarence Lagerstam, who lives in Kristianstad in Skåne found a small piece of bone when he was searching in an area popular with fish and reptile fossil hunters.

“I did not think there would be more, but then I found more smaller fragments and I became more and more excited,” he told Swedish news network SVT.

Experts believe the bones are the remains of a large carnivorous dinosaur that lived on what is now Swedish soil around 80 million years ago when the region had a warm climate, similar to that in the Mediterranean today.

Lagerstam has kept his finding in a black cardboard box, wrapped in paper towels, but has opened it several times this week to show off what he calls his “dream” finding to the Swedish media.

Johan Lindgren, a paleontologist and researcher at nearby Lund University says it is “fantastic” that the schoolboy made the finding in an area where experts have been searching for fossils for 150 years.

“You can never stop being fascinated by what is actually out there in the Swedish soil,” he told SVT.

Lagerstram says he first became interested in fossils and dinosaurs when he watched the movie Jurassic Park and plans to continue with his interest.

“It’s a great feeling to be able to read about ancient ecosystems and to learn what prehistoric animals looked like, how they lived and how they interacted with their environment”.

Why we bring the first T-Rex to Europe: Anne Schulp at TEDxLeiden

25 January 2014

We are increasingly confronted with the consequences of global warming and the loss of bio-diversity. The more we understand and appreciate the wonder of nature, the better we are able to sustain our life on this planet. This is where the T-Rex comes in. Can you imagine another creature that has been able to better capture the imagination of kids? This is why we decided to go on an epic journey to find a real T-Rex and bring it to Europe. We believe that through telling the story of this T-Rex and its excavation we can get more kids to experience the wonder of life on this planet.

Paleontologist Anne Schulp is a researcher at Naturalis Biodiversity Center in Leiden. The natural history collection of Naturalis is extensive, but one kind of dinosaur was conspicuously absent: a large carnivore. This changed recently, when Anne helped excavating a Tyrannosaurus fossil in Montana, USA.

Translated from NOS TV in the Netherlands today:

About one and a half years from now, for the first time ever a skeleton of a Tyrannosaurus rex will move to outside the United States, namely to the Netherlands. Naturalis Biodiversity Center in Leiden has received 5 million to buy a skeleton of the dinosaur. It was excavated in 2013 in the US state Montana.

Last year, scientists at the research institute and natural history museum excavated large parts of the Tyrannosaurus rex in Montana. It is a well-preserved skeleton of a then probably 30 years old female. …

Naturalis has received a part of the money through crowdfunding.
