31. Crocs are more closely related to birds than snakes or lizards.

http://www.ucmp.berkeley.edu/diapsids/archosy.html

"Dinosaurs are a specific subgroup of the archosaurs, a group that also includes crocodiles, pterosaurs, and birds. although pterosaurs are close relations, they are not true dinosaurs. Even more distantly related to dinosaurs are the marine reptiles, which include the plesiosaurs and ichthyosaurs."

I tend to agree with the classification, but you are correct, I should not call a croc a dinosaur. They are very, very close cousins and they existed at the same time, and crocs and birds share a common dino ancestor, but they are not dino's themselves.
