University of Chicago paleontologist Paul Sereno describes Spinosaurus aegyptiacus, a predator of the Cretaceous Period that had adapted to life in water 95 million years ago. Sereno, his UChicago colleague Nizar Ibrahim, and an international team of associates announced their discovery in the journal Science online, at the Science Express website, on 11 September.

I wouldn't be surprised if alligators/crocodiles are closely related to this thing, they look much alike, and all three are semiaquatic.

Life started from the sea they say....

I love how the thigh bone looks like a huge mammalian thigh bone.

Probably. But I think life has gone back and forth, between land and sea several times. Sometimes events happen, and life must change in order to survive.

I'm trying to think of a specie of this kind.
