Those look like crocodylians. But with the 250 million year history of that order, it's impossible to ID them without being able to handle them or look them up.

There are 23 current species and 100's of extinct ones, more if you include similar looking species from the diapsida sub-group.

I'm not sure what your point is.

His point, apparently, is that paleontologists aren't allowed to use source materials or their education to identify skull and bone samples. I think it's found under section 2, subsection b (iv) of the Paleontologist Rulebook -- which reads -- "With each find, a working paleontologist in the field must forget all prior knowledge and eschew all reference materials, make a wild-ass guess at what he's holding in his hand, and avoid at all costs any further examination of the find after a shower and a shave."

Those look like crocodylians.

One is, one ain't. The one that ain't is Eryops, a giant amphibian which existed about 300 million years ago. The other one is of a modern caiman.

My point is, it's relatively easy to misidentify two fossils that very far divergent--even when we have full skulls or skeletons (which is the exception, not the norm). Granted, a trained paleontologist is going to be a lot better at it than you or I, but they're still prone to mistakes and have made many of them over the past century.
