| THE CROCODILE AND ALLIGATORSMembers of the subclass archosaur, crocodilians have been discovered in the same rock layers as popular dinosaurs. The Protosuchus crocodile has been found in the Triassic and Deinosuchus in the Jurassic. Some of these specimens appear from their hip and leg bones to be more agile (and arguably better "fit") than today's varieties. A fossil crocidilian has been found with molars, giving evidence that the ancient ancestors were omnivorous (again exhibiting loss of function over time). You can learn a bit more about modern varieties at the following displays: |
