Dinosaurs

A new study has analyzed asteroid dust recently discovered in the Chicxulub asteroid crater. The findings further support the theory that the dramatic impact was the cause of the mass extinction event that wiped out the dinosaurs.

A new study published in the journal Nature is describing the extraction and sequencing of the oldest known sample of DNA. The sample comes from an ancient species of mammoth found in the Siberian permafrost and dates back nearly 1.2 million years.

According to a new study, the impactor that smashed into Earth’s surface millions of years ago – causing the global extinction event that wiped out the dinosaurs – may have originated from a vast sphere of icy debris that surrounds the solar system.

Just last year, scientists declared that Spinosaurus was the first dinosaur known to swim through the water, preying upon fish as it did so. A new study, however, suggests that it was probably more of a shore-based feeder.

Probably the world's most famous family of dinosaurs, the tyrannosaurs included the 40-ft (12-m) Tyrannosaurus rex within their ranks. Newly studied fossils now suggest that the reptiles were about "the size of a border collie" when first hatching.

Tyrannosaurus rex may have ruled the land in the time of the dinosaurs, but the mosasaur was likely the most ferocious reptile in the sea. A new species of the creature was recently classified, which distinguished itself with teeth like those of a shark.

Paleontologists have found and described what may be the last dinosaur body part we didn’t know anything about – the butthole. Better yet, it seems like it might have evolved to look and yes, even smell, nice to suitors.

Paleontologists have discovered a new species of dinosaur that’s a real show-off. Ubirajara jubatus is a small creature found with strange spikes sticking out of its shoulders, which scientists speculate were used as ornaments, like a peacock’s tail.

A tyrannosaur and a triceratops, locked in combat for 67 million years, will soon be on public display for the first time. Known as the Dueling Dinosaurs, the incredible fossil captures predator and prey preserved together, seemingly mid-battle.

The bones of the only dinosaurs to be found on the island of Ireland have been confirmed by researchers. The two bone fragments were found to belong to two different individuals and date from the early Jurassic period, or about 200 million years ago.

If the movie Jurassic World is to be believed, pterosaurs could easily catch human-sized prey. A newly discovered species of the prehistoric reptile wouldn't have posed much of a threat to us, however, as it likely fed more like a modern sandpiper.

The mosasaur was likely one of the most ferocious prehistoric marine predators. A previously unknown species of the reptile has now been classified, and it sported a crocodile-like snout that may have allowed it to catch prey that others missed.
