These bones fit together in one of two configurations: ornithischian (bird-hipped) or saurischian (lizard-hipped). They had an upright gait. Dinosaurs held their bodies over their legs like rhinoceroses do, rather than using the sprawling gait that crocodiles do. Non-dinosaur Prehistoric Animals...
For 130 years, we thought we understood the broad architecture of the dinosaur family tree. British palaeontologist Harry Seeley pointed out in 1887 that dinosaurs could be divided into two groups based on whether their hips were lizard-like (where the pubis points forward) or bird-...
that could do a huge amount of damage to us as a civilization. So, now that I've scared the crap out of you -- 00:00 (Laughter) 00:00 what can we do about this? This is a potential threat. Let me note that we have not had a giant impact like the dinosaur killer fo...
Tyrannosaurus and sauropod dinosaurs also inhabited the area between approximately 66.4 and 68.2 million years ago, according to a few additional dinosaur bones found in the area. Before the mass extinction, central China had a low diversity of dinosaur species throughout the previous 2 million years...
Why don't we use radiocarbon dating for dinosaur bones? How do scientists know about the Triassic Period? Why are metamorphic rocks unreliable for radiometric dating? How is biology used in paleontology? Why is absolute dating used on fossils? How does photosynthesis of plants affect radiocarbon ...
Just 50 years ago, no one knew why the Earth has mountains. Now we do. This is the story of how we figured it out - and how we keep learning.
This short article from the UC Museum of Paleontology, on paleontologist Matt Wedel, discusses the early evolution of airspaces in dinosaur bones and what this can tell us about other parts of dinosaur anatomy that do not fossilize well. http://www.ucmp.berkeley.edu/science/profiles/wedel_0609...
And, for some chickens, the day comes when they are no longer wanted. That’s when the man of the house marches into the yard, puts the bird in the back seat and drives to Whitacre’s farm, leaving the chicken with her, whimpering that he just can’t bring himself to do what has...
What do you call it (‘cause I’m him (see also Robert Downey, Jr. in “The Singing Detective”) Are you faking?) Are we faking? Or, have you heard this all over? A machine, two road miners, 5:30. I can’t compete. So I can’t compete, the monsters will be showing (of,...
