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.
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.

Scientists thought climate and ecological change was the culprit, but a new study suggests otherwise.
The mysterious aquatic creature lived 300 million years ago, and its fossils have stymied scientists for more than 50 years. New research solves some of the mystery.
