Which Era Is Known As the Age of Reptiles? The Mesozoic Era is also known as the Age of Reptiles or the Age of Dinosaurs. During the era, dinosaurs were the Earth's dominant form of life. Continue Reading. The Mesozoic Era is divided into three different periods: the Triassic, the Jurassic, and the Cretaceous. It spanned from approximately 245 million years ago to 65 million years ago.The Mesozoic Era was followed by the Cenozoic Era, which is the current era. The Mesozoic Era ended with the extinction of the dinosaurs.

The Age of Reptiles The Age of Reptiles is a 110-foot mural depicting the period of ancient history when reptiles were the dominant creatures on the earth, painted by Rudolph F. Zallinger. The fresco sits in the Yale Peabody Museum in New Haven, Connecticut, and was completed in 1947 after three years of work. The Age of Reptiles was at one time the largest painting in the world, and depicts a span of nearly 350 million years in Earth's history. Painted in the Renaissance fresco secco technique, The Age of Reptiles

Cenozoic The Cenozoic Era is the current geological era, covering the period from 66 million years ago to the present day. The Cenozoic is also known as the Age of Mammals, because of the large mammals that dominate it. The continents also moved into their current positions during this era.

Invertebrates like brachiopods, gastropods, and molluscs were severely affected.

- The Mesozoic Era. The Mesozoic Era is divided into three time periods: the Triassic (251-199.6 million years ago), the Jurassic (199.6-145.5 million years ago), and the Cretaceous (145.5-65.5 million years ago).*. Mesozoic means middle animals, and is the time during which the world fauna changed drastically from that which had been seen in the Paleozoic.

Dinosaur Dinosaurs are a diverse group of reptiles of the clade Dinosauria that first appeared during the Triassic. Although the exact origin and timing of the evolution of dinosaurs is the subject of active research, the current scientific consensus places their origin between 231 and 243 million years ago.

Mesozoic Era: Age of the Dinosaurs During the Mesozoic, or Middle Life Era, life diversified rapidly and giant reptiles, dinosaurs and other monstrous beasts roamed the Earth. The period, which spans from about 252 million years ago to about 66 million years ago, was also known as the age of reptiles or the age of dinosaurs.

The Cretaceous is usually noted for being the last portion of the Age of Dinosaurs, but that does not mean that new kinds of dinosaurs did not appear then. It is during the Cretaceous that the first ceratopsian and pachycepalosaurid dinosaurs appeared.

Paleozoic Era Paleobiology The Permian Period extends from about 286 to 245 million years ago, and is the last geological period of the Palaeozoic Era. The Permian was named in the 1840s by Sir Roderick Murchison, a British geologist, from the extensive Permian exposures near Perm in Russia.

TRIASSIC 245 to 208 million years ago. 1  During the Triassic period, all land on Earth existed as one enormous mass. It was called Pangaea. 2  Some reptiles, frogs, turtles and crocodiles existed earlier, but dinosaurs didn’t appear until late in the Triassic period. 3  The period marked the rise of small, lightly built dinosaurs.

The Geologic Time Scale Over time, life forms change. Their fossil record allows geologists to date and compare rocks across geological time. For example, dinosaur fossils are only found during the Mesozoic era some 245 to 65 million years ago. The following table shows the geologic time scale. Phanerozoic Eon. The period of time, also known as an eon, between the end of the Precambrian and today, The Phanerozoic begins with the start of the Cambrian period, 544 million years ago. It encompasses the period of abundant, complex life on the Earth.

Terrestrial reptiles and the first mammals Whereas Early Triassic forms were still Paleozoic in aspect, new forms appeared throughout the period, and by Late Triassic times the tetrapod fauna was distinctly Mesozoic in aspect. Modern groups whose ancestral forms appeared for the first time in the Middle and Late Triassic include lizards, turtles, rhynchocephalians (lizardlike animals), and crocodilians. The mammal-like reptiles, or therapsids, suffered pulses of extinctions in the Late Permian.

- The Jurassic is an age that began about 200 million years ago and stretched for about 50 million years to about 150 million years ago. Radiometric dating can identify certain materials as being from that period, but we don't have a radiometric system for the Jurassic, per se.

What Are the Life Forms of the Cenozoic Era? The Cenozoic Era is known as the Age of Mammals. This era is broken down into time periods according to the life forms that lived during that time. In the Paleogene Period, rodents, small horses were common and rhinoceroses and elephants first appeared. By the end, dogs, cats, and pigs became common mammals.
