Re: Jurassic Croc Found With Fish Like Tail

These notable features of the Jurassic crocodile (needle teeth, forked fish-tail, scales or scutes)

Scales are not preserved -- in fact, as carbonized soft-tissue remains from Germany show, the metriorhynchids had lost them (like the ichthyosaurs). The tail is like an ichthyosaur's, too -- that is, the vertebral column is kinked downwards. In the absence of soft-tissue remains, few people will guess that the part behind the kink supported the lower lobe of a forked tail fin.

The head is hard to get wrong, however! You may well be right just because of this alone.
