fossil of the weekend! #67

a rather lovely original skull of a champsosaur, the "crocodile lizard" which is the perfect name for this critter. despite its crocodilian appearance, champsosaurs were a type of lizard like reptile that independantly reentered the water and evolved very similar characteristics to crocs. a perfect example of convergent evolution, where two animals living the same life style tend to evolve similar (but yet subtley different) means of living that same life.

How strange that convergent evolution was taking place even back then when vertebrate animals seemed to first begin evolving.

The fossil looks lovely, looks like quite a precise predator.
