Mesozoic means "middle animals", and is the time during which the world fauna changed drastically from that which had been seen in the Paleozoic.
Dinosaurs, which are perhaps the most popular organisms of the Mesozoic, evolved in the Triassic, but were not very diverse until the Jurassic.
Except for birds, dinosaurs became extinct at the end of the Cretaceous period. Some of the last dinosaurs to have lived are found in the late Cretaceous deposits of Montana in the United States.
The Mesozoic was also a time of great change with terrestrial vegetation. The early Mesozoic was dominated by ferns, cycads, ginkgophytes, bennettitaleans, and other unusual plants.
Modern gymnosperms; such as, conifers, first appeared in their current recognizable forms in the early Triassic. By the middle of the Cretaceous period, the earliest angiosperms had appeared and began to diversify, largely taking over from the other plant groups.
