Inner Reptile

The ancient enviornments preserved in the orange rocks that form the cliffs around Bay of Fundy are those that contained lake beds, streams, and deserts. Where the fossils were found was not the normal enviornment that fossils were preserved in which was basalt, rock formed from cooked lava. But it was among this rock that a jaw was found that belonged to a creature called the Tritheledont. This animal was extremely mammal like but it still retained many reptilian traits. One way that mammal's skin differs from that of a reptiles is that mammal's skin keeps the skin moisturized unlike reptiles, the skin is a lot softer while a mammals is a lot dryer. The tritheledont have teeth that have cusps made for chewing food while the gorgonopsid does not. The gorgonospid is over 250 million years old and have giant elongated canines that are used to pierce skin.
