How Do Creationists Know What Dinosaurs Looked Like?

From Chasing the Raptor

“While watching a video of the Creationist Museum in Kentucky, with its impressively-detailed animatronic full-scale dinosaur models, I was struck by the thought: how do creationists know what dinosaurs looked like? I mean: there are these moving, snarling model dinosaurs in an institution which has elevated pseudoscience to the dubious level of a theme park attraction, and whose staff (at least, in the various interviews which I have seen them give) appear to have a near-pathological disdain for the scientific method. So how do creationists know what dinosaurs looked like?”

Wandering scholars discover the Page Museum at La Brea Tar Pits.

Recent travels allowed for a quick visit to the Page Museum at the La Brea Tar Pits.  Now in their one hundredth year of excavation, the site has yielded over 600 species to date with a NISP of over 3.5 million (not counting over 200 bacteria).  It’s a remarkable place and I feel privileged to to have been given an excellent tour by Dr John Harris and Curator Gary Takeuchi.  Tar still bubbles and oozes and excavations continue, thanks in part to continuing growth of this highly urbanized area.

Although most of the tar seeps are closed off for safety, a couple can be accessed with a guide.  The surface is just as deceptive as it is described and is often covered with leaves and dirt.  The tar can also be deceptively solid feeling until the incredible stickiness locks your feet to the tar.  Dr Harris provided a great example by having us poke the tar with a wooden lath.  Even though it is solid enough to resist the lath for more than a top inch or two, it is extremely difficult to pull it back out again and it’s easy to imagine a hooved animal becoming mired almost instantly to await it’s demise by large cat or wolf or even thirst.

You just gotta poke it with a stick…

For reasons that aren’t completely clear, there are an extremely high number of predators and scavengers in the mix, implying that many carnivores may be tempted by a struggling animal but the more cautious grazers were likely scared away by their thrashing comrades.  The upshot of this is an enormous number of coyotes, wolves, saber-toothed cats, short-faced bears, and American lions as well as the full gamut of vulture-like birds filling these pits and seeps.  Below I am holding the humerus of a Smilodon fatalis, a prevalent creature at the Tar Pits.

We had a wonderful tour of the “fish-bowl” lab by Shelly Cox.  Here we examine the newly cleaned mammoth tusk.

Tusks grow like tree-rings and tell scientists a lot about the environment the creature lived in by proxy.  A section of this particular specimen has been removed for analysis already.

Cranium of a very familiar looking mammoth. Although not found inundated in tar, there is still enough in the sediment that it is oozing from the cleaned skull.

For anyone interested in Ice Age fauna, the Page Museum is a definite “must see” stop on the journey through life.

30,000 year old Mammoth from the Russian Arctic

A couple of months ago, Yevgeny Salinder, an 11 year old Russian boy, discovered a 30,000 year old mammoth thawing from the permafrost in the arctic Krasnoyarsk region. I have been hoping to hear more about this remarkable find but, of course, these things take time.

There is already some important information coming out about this find, including the discovery of large fat storage in the form of a hump on the mammoth’s back, confirming images from the Pleistocene depicting the humped back.  Previously the hump in the art work was attributed to large thoracic spines but now it seems to be more camel-like soft tissue.  Intact organs should tell us more about the animal and it’s environment than we have known.  As the Arctic ice recedes, it seems we will find more and more of these specimens being exposed.

Mammoths didn’t go out with a bang

From Nature

Study suggests Beringia’s shaggy behemoths went extinct after a slow and gradual decline.

“Why are there no more woolly mammoths? The last isolated island populations of these huge beasts disappeared about 4,000 years ago — well after the Pleistocene extinction that wiped out much of the world’s megafauna — but what triggered their demise remains a frustrating mystery. According to the latest study to contribute to the ongoing debate, the last mammoths disappeared after a long, slow decline in numbers rather than because of a single cause.”  Read on.
