Taken with my new microscope camera.  The first three pictures will be of crocodile teeth from the Hell Creek formation of Montana and are from the Cretaceous period.  All are taken at 20x to show a lot of detail. 

First photo:  Borealosuchus Sternbergi is 4.5 mm long.

Second photo: Champosaurus sp. is 3 mm long.

Third photo: Brachychampsa montana
