Before the dinosaurs there was a plethora of life including fish, trilobites, lungfish, amphibians, and plenty more.
In the Proterozoic era (2 billion to 650 million years ago) there was an assortment of single-celled and simple multi-celled creatures. The next 200 million years (early Paleozoic) showed a great expansion of life in the seas, including a diverse assortment of corals, mollusks, trilobites, sponges, shrimps, and other creatures. the next 150 million years (late Paleozoic) included the development of fish, land plants, insects, amphibians, and ultimately reptiles and flowering plants. The earliest dinosaurs began roughly 250 million years ago (the Mesozoic).
