"Kung Fu" Stegosaurus Had Deadly Fighting Moves

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. » 10/24/14 6:40am 10/24/14 6:40am

Before Whale Falls, There Were Ichthyosaur Falls

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. » 9/11/14 5:33pm 9/11/14 5:33pm

Further evidence that volcanoes can destroy life on Earth

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. » 3/21/13 2:31pm 3/21/13 2:31pm

Most violent fossil ever shows the final record of a three-way hunt

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. » 3/14/12 4:30pm 3/14/12 4:30pm

This giant fossil flea once feasted on dinosaurs

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. » 2/29/12 12:03pm 2/29/12 12:03pm

Giant asteroids might have began the age of dinosaurs as well as ended…

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. » 11/16/11 12:57pm 11/16/11 12:57pm

Evidence for huge dinosaur migrations that once took place in ancient…

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. » 10/27/11 5:30pm 10/27/11 5:30pm

Virgin birth has been discovered in pit vipers

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. » 10/18/11 3:20pm 10/18/11 3:20pm

Carnotaurus had the most ridiculously powerful dinosaur tail ever

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. » 10/16/11 11:15am 10/16/11 11:15am

Carnotaurus had the most ridiculously weak dinosaur arms ever

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. » 9/25/11 11:30am 9/25/11 11:30am

190 million year old dinosaur eggs are the world's oldest preserved…

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. » 11/15/10 2:11pm 11/15/10 2:11pm
