The Mesozoic Era, comprising the Triassic (∼252–201 Ma), Jurassic (∼201–145 Ma), and Cretaceous (∼145–66 Ma) periods (Cohen et al., 2013), marked a transition from the last supercontinent Pangaea toward today's fragmented continental configuration and from “old” (Paleozoic) to “new” (Cenozoic) biota that are now integral parts of the modern world (e.g ...The Mesozoic Era is literally the era of “middle life.”. It is also known as the age of dinosaurs. It lasted from 245 to 65 million years ago and is divided into the three periods described in Figure below. The Mesozoic began with the supercontinent Pangaea. Then, during the era, Pangaea broke up and the continents drifted apart.Wikimedia Commons. Ornithopods —small- to medium-sized, bipedal, plant-eating dinosaurs—were some of the most common vertebrate animals of the later Mesozoic Era.

Periods of the Paleozoic Era. The Paleozoic Era begins after the Pre-Cambrian about 297 million years ago and ends with the start of the Mesozoic period about 250 million years ago. Each major era on the Geologic Time Scale has been further broken down into periods that are defined by the type of life that evolved during that span of time.

Geologic Time Scale. Humans subdivide time into useable units such as our calendar year, months, weeks, and days; geologists also subdivide time. They have created a tool for measuring geologic time, breaking it into useable, understandable segments. For the purposes of geology, the “calendar” is the geologic time scale.This vast orogenic belt formed during diachronous terminal closures of different Neotethyan seaways, which originally evolved between Eurasia in the north and the Gondwana–derived continental blocks in the south throughout the Mesozoic (Dilek and Moores, 1990; Dilek and Furnes, 2019, and references therein).
