[1] Polyphyodonts include most toothed fishes, many reptiles such as crocodiles and geckos, [2] [3] [4] and most other vertebrates, mammals being the main exception, though not absolute.
Crocodiles with teeth the size of bananas were apparently a nightmare that actually existed during the Late Cretaceous period. A pair of researchers with the University of Iowa decided to re ...
In general, in crocodiles and gharials, both rows of teeth are visible when the jaws are closed because their teeth fit into grooves along the outside lining of the upper jaw. By contrast, the lower teeth of alligators and caimans normally fit into holes along the inside lining of the upper jaw, so they are hidden when the jaws are closed.

It had large, robust teeth built for crushing, and its back was covered with thick hemispherical osteoderms.
