The Mesozoic Era (252 million years ago to to 66 million years ago) is a geologic span of time on Earth which includes the Triassic, Jurassic and Cretaceous Periods, an era populated by dinosaurs.

Conditions in this era included seismic activity, volcanoes, and violent storms. Lifeforms included tree ferns and pterosaurs. (VOY novel: Pathways)

HistoryEdit

252 million years ago, 90% of Earth species died within a span of one million years during the Permian-Triassic Extinction Event. (TLE novel: The Buried Age)

65 million years ago, an asteroid impact near the Yucatan Peninsula in Mexico created an extinction event that killed off most of the dinosaurs.

In an alternate timeline when the impact was prevented, descendants of Mesozoic wildlife were discovered on Earth by the USS Enterprise, including ammonites, shellfish, plesiosaurs, man-o-wars, and sharks. (TOS novel: First Frontier)
