Extinct Animals

Extinct animals are those species which are no longer living. This group includes prehistoric animals like dinosaurs and ice-age mammals, as well as moden species like the Dodo.


Someone just paid $2.36 million to take home an exquisite dinosaur skeleton. The sale has added to the growing scientific anxiety about the commodification of precious, irreplaceable fossils.

New research suggests the asteroid impact that killed the dinosaurs probably burned Earth's forests, requiring modern birds' common ancestors to live on the ground.

Massive mastodons roamed lower Kentucky during the last ice age. Jefferson was so fascinated by the creatures he was convinced they still roamed the plains in the 1800s.

University of Kansas paleontologists are comparing the bones of a new T. rex to determine if they've got a juvenile Tyrannosaurus or a mature Nanotyrannus on their hands.

Walking evolved not on land but underwater.

Could this exciting find help bridge the gaps between Africa's late Cretaceous fossil record and that of other continents?

The fossilized find provides us with another example of the oldest bird species we know of.

Paleontologists in China hit the jackpot of fossilized pterosaur eggs.

The American Southwest was once prime tyrannosaur country, as a newfound skeleton reminds us.

Scientists are at odds about whether Velociraptors worked together to take down their prey.

A new study found that the Beelzebufo frog had a bite strong enough to take down dinosaurs.

Instead of a mouth, the hell ant had blades and a metal horn to catch its prey. Ouch.

A new study suggests the extinct aquatic reptiles used all four flippers for uniquely efficient underwater motion.

Tyrannosaurus rex was a giant predator that roamed the earth, so why did it have such tiny arms?

Scientists generally agree that dinosaurs sported colorful, feather-like plumage. So do moviemakers lack imagination, or do audiences?

Accidentally tripping on and discovering the fossilized skull of an extinct giant elephant seems like a 9-year-old's dream come true.

The megapodes were supertall, but that didn't keep them from taking flight.

The colossal footprints of an herbivorous dinosaur found in western Australia might belong to the biggest dinosaur ever.

When we think venom, we think cobras and vipers. But Euchambersia was a reptile, a mammalian ancestor, and venomous, according to new fossil analysis.

This insect's appearance and characteristics are so unusual, it has received its own scientific order.

Based on some baby dinosaur teeth, scientists have figured out just how long dinosaur eggs incubated. (The answer? Long. Too long.)

And, to top it all off, it's got feathers on it.

A recent discovery of the partial skeleton of a small pterosaur calls into question whether flying reptiles of the Late Cretaceous were all humongous.

The method this ancient carnivore employed is unlike anything we see in predators today.

A small island off the coast of Alaska supported a mammoth population until sea levels rose and fresh water sources shrank.
