A fossilized snake that lived 10 million years ago retained cell structures that revealed to scientists the colors that would have dappled its skin while the animal was alive.
Amber-imprisoned lizards from Southeast Asia that date back 99 million years ago make up the oldest assemblage of tropical lizards ever found in amber.
Astonishingly well-preserved Cretaceous lizards caught in amber include specimens with intact skin, visible skin pigment, and soft tissues — and in one case, a lolling tongue.
Pareiasaurs — barrel-chested and stubby-legged turtle relatives that lived during the Permian era — ranged far and wide on land, according to a new study.
Two species of venomous sea snakes that were thought to be extinct have been discovered slithering off the coast of western Australia.
The ancient, four-flippered plesiosaur didn't swim like a fish, whale or even an otter — but instead like a penguin, a new study finds.
A long-necked plesiosaur with enormous flippers once swam around the waters covering Patagonia about 65 million years ago, new research finds.
The culprit behind a disease that causes raised blisters, crusted-over eyes and snouts, discolored skin patches, and ultimately death in several snake species has been identified.

Images of snake embryos reveal how genes that enhance the growth of limbs are used to grow the phallus for these legless reptiles.
