Ever wanted to see inside the body of a crocodile in the highest of resolutions? Now you can, thanks to Ohio University Professor of Anatomy and Paleontology Larry Witmer. To understand dinosaur anatomy, he's turned to birds and crocodilians, their closest living relatives.
Chameleons are famous for changing color in order to blend in with their surroundings. This little guy doesn't really need to, though; at just an inch long he's the smallest chameleon in the world.
320 million years ago, mammals and reptiles reached an evolutionary parting of the ways. We've now sequenced a lizard genome for the first time ever, and it's vastly different from our own...but in a few crucial ways, it's shockingly similar.
This California King Snake amazingly has two rare disorders: it's albino and has two heads. That combination only comes about every 50 years. Surprisingly though, the two-headedism (or polycephaly) of the snake is actually more common than albinism.
This is Dimetrodon, the world's top predator about 270 million years ago. Living before the dawn of the dinosaurs, this striking creature was actual a distant ancestor of mammals like us. Now we've discovered the most complete Dimetrodon skeleton ever.
The complex evolutionary relationships between birds and dinosaurs has only really started to become clear in the last 15 years. But one brave thinker in 1897 knew the real truth: it was all down to birds and reptiles doing it.
