OTHER ANIMALS AND PLANTS IN THE TRIASSIC PERIOD
During the late Triassic, 220 million years ago, the first true mammals appeared, like Eozostrodon.
Some scientists believe that mammals evolved from a group of extinct mammal-like reptiles, which were Therapsids.
These primitive mammals were tiny and are thought to have been nocturnal. The earliest known turtle, Proganochelys, appeared during the late Triassic., frogs, salamanders, lizards, turtles, (including snakes),
and Pterosaurs first appeared in the Triassic period.
Also in the Triassic was Pseudosuchia, possible ancestor of Archaeopteryx. Aetosaurs like Desmatosuchus lived during the late Triassic period.
Insects began to undergo complete metamorphosis from larva through pupa to adult. (This bug actually lives today….but it sure looks prehistoric)
In the seas, Ichthyosaurs, marine reptiles, appeared.
