What is mesozoic era
Of the many species on earth today that can trace their ancestry back to prehistoric times, evolution has touched crocodiles perhaps least. Along with pterosaurs and dinosaurs, crocodiles were an offshoot of the archosaurs, the "ruling lizards" of the early-to-middle Triassic period of the Mesozoic Era.This epoch in history began about 251 million years ago and ended 65 million years ago.The Cretaceous Period ends with one of the greatest known extinction events, so severe it also marks the end of the Mesozoic Era. Dinosaurs, pterosaurs, mosasaurs, and ammonoids, to name a few, were among the groups lost at this time. The Cretaceous extinction event is marked by the famous K-T boundary and asteroid impact on what is now the ...

First of all, most of the plants around us today are flowering plants, and these did not evolve until relatively late in the Mesozoic (about 140 million years ago). Second, the Mesozoic Era was much sparser than today in both plant and animal life.Geologic time is the billions of years since the planet Earth began developing.

The Mesozoic Era is an interval of geological time from about 252 to 66 million years ago.
