In this age the animals and plants begin to resemble existing species. The age is characterized mainly by the preponderance of reptiles, many of which were very large, as, for example, the plesiosaurus, an animal with a long, snake-like neck and a huge body, or the ichthyosaurus, with a head like a crocodile and short neck and large body. Both of these animals were furnished with fin-like paddles, and lived in water.
