Stegosaurus are often portrayed as lumbering plant eaters. But they were lethal fighters when necessary, according to paleontologists who recently uncovered evidence of a carnivorous Allosaurus who was mortally wounded in combat, 147 million years ago.
When a whale dies out in the open ocean, its body slowly drifts to the seafloor, where it breathes life into a temporary ecosystem. But whales weren't the first ones to live on after death; Jurassic giants did too.
It's a universal truth that Jurassic Park is a near-perfect movie, which is why its 20th anniversary re-release in 3D has elicited both elation and groans from fans. Yay, hurray, Jurassic Park in theaters! Uh oh, I hope the 3D conversion doesn't ruin the film!
If you think asteroid strikes are scary, I've got some bad news for you. The most deadly events on Earth are caused by . . . Earth. New evidence suggests that underwater volcanoes may have wrecked our planet for thousands of years, and ultimately allowed dinosaurs to rule the world.
A lot of dinosaurs were big eating machines. Now, scientists have calculated how much gas they would have expelled as a result of their digestion—and the quantities they produced probably meant that they warmed their own climate through letting rip.
150 million years ago, a flying reptile saw a fish in the waters of the Jurassic Ocean. The reptile caught its prey...and then was almost immediately grabbed by a much larger fish. That's when things really started to go wrong.
Can you imagine the scene above in real life, not just its eternal stone ghost? Picture these ugly monsters. On the left, a pterosaur. A flying reptile chomping down a small prehistoric fish. On the right, a large herring eating the pterosaur.
This fossil reveals a flea that is about twice as big as any known species alive today. It dates back about 165 million years, and its razor-sharp mouth likely evolved for one purpose: to pierce and feed on dinosaur hides.
How the dinosaurs died is maybe the most well-known story in all paleontology, but the dinosaurs' origins are more obscure. Dinosaurs might well have gotten their chance to rule the planet from the very thing that later killed them off.
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.
Chalk another one up to Jeff Goldblum — researchers say that female pit vipers, like the copperhead snake pictured up top, have joined the growing ranks of animals known to be capable of reproducing asexually, i.e. without mating with a member of the opposite sex.
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.
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.
It was one of Hollywood's first modern CGI marvels, but it's taken quite a while for Universal to say the magic word on a Blu-ray release for the Jurassic Park (for now still a) Trilogy. No more—it's out this October 25th. Nature found a way. [Engadget]
Paleontologist Jack Horner wants a pet dinosaur. (I'm right there with you, Jack.) And according to his TED talk, we're actually getting closer to making Jurassic Park a reality. Thanks to chickens.
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.
