Crocodile skute (armour) and tooth
Crocodiles are covered with a protective layer of hard, bony skutes and these have a very distinctive pattern even when worn by the sea as in this example. When you compare them to some of the armoured skull plates of the Triassic amphibians, it’s easy to understand why, when they were first found, they too were thought to be crocodiles. There are also two teeth in this image and they both show signs of wear.
