Pity the poor Tyrannosaurus. With those teeny little arms and that great big body, T-Rex is incapable of doing things that come easily to you and me. More »

Although a few dinosaurs were adapted to live underwater, most dinosaurs were landlubbers through and through. And perhaps no dinosaur had less business going for a swim that this fellow, the heavily-armored, 13,000-pound Ankylosaurus. More »

Rapetosaurus was a huge, plant-eating dinosaur much like the brachiosaurus. It's one of a family of dinosaurs that had a huge, hollow bone growing in its back. Known as an osteoderm, paleontologists are only now discovering what it was for. More »

How dinosaurs spent their lives remains a great mystery of paleontology. We know they ate a lot, and presumably they had sex somehow. But it's almost impossible to prove the existence of more complex dinosaur behaviors...until now. More »

Triceratops has captured the public imagination ever since the first fossils were discovered in 1887. But it's hardly the only horned dinosaur that once roamed the Earth. Meet the two-horned zuniceratops, oldest of the American relatives of triceratops. More »

Here's a nice counterbalance for our previous report on Carnotaurus's wimpy arms - it turns out any shortcomings in its arms were more than made up for with its super-strong tail, which made it one of the fastest hunters around. More »

The image of the hulking T. rex and its comically undersized arms is deeply ingrained in pop culture, but it isn't really fair. They were muscular little appendages well-suited to their evolutionary purpose. The wimpy-armed Carnotaurus is another story entirely. More »

We recently asked three of Jurassic Park's special effects wizards what they'd do with dinosaurs today, using all-new technology and cutting-edge paleontological knowledge. Here's what they had to say, and how it will affect the new Jurassic Park blu-rays. More »

Sharks weren't always the huge, vicious alpha predators that they are today. Hundreds of millions of years ago, they were just another tiny little harmless fish species hanging out in lakes and rivers. So yeah...things have changed slightly since then. More »

This is an artist's conception of the river turtle Boremys, which is one of the first known species whose existence actually improved in the immediate aftermath of the massive extinction event, 65 million years ago. More »

It might not be immediately obvious just how birds could evolve something as complex as the wings needed for flight. But that's just it: flight was basically incidental to the real adaptation. The secret is a little something called flap-running. More »

A tiny neck bone fossil measuring just a quarter-inch long was recently discovered in southern England. Dating back between 145 and 100 million years ago, the dinosaur that this bone belonged to can't have been more than 20 inches long. More »

Paleontologist Jack Horner is like a lot of us: as a child, he wanted a pet dinosaur — a dream he's working to make reality. In a recent TED talk, Horner explained why the Chickensaurus is dinosaur's best hope. More »

Brontomerus literally means "thunder thighs" in Greek, and this particular dinosaur definitely earns the name. It had extremely strong back legs, allowing it to unleash devastating kicks on rivals or predators, as you can see in this absolutely incredible illustration. More »

When we think of T. Rex, we imagine the most frightening predator that ever walked the Earth, stalking through the Cretaceous in search of unsuspecting herds of plant-eating dinosaurs. But the real story might not be quite as scary...or flattering. More »

This is Dimetrodon, the world's top predator about 270 million years ago. Living before the dawn of the dinosaurs, this striking creature was actual a distant ancestor of mammals like us. Now we've discovered the most complete Dimetrodon skeleton ever. More »

The complex evolutionary relationships between birds and dinosaurs has only really started to become clear in the last 15 years. But one brave thinker in 1897 knew the real truth: it was all down to birds and reptiles doing it. More »

Dinosaur eggs dating back to the early Jurassic are revealing amazing secrets about dinosaurs. These particular dinosaurs were born quadrupedal, then learned how to walk upright, revealing drastic physical changes and a very human-like reliance on their parents during infancy. More »

Popular images of the prehistoric world are filled with spiny stegosauri, placid brachiosaurs, and rampaging tyrannosaurus rex. But one image we may need to revise is that of pterodactyls flying overhead. New research suggests the winged lizards were far too massive to stay aloft, although some paleobiologists are inclined to disagree. More »
