The Mesozoic Era The Age of Dinosaurs The dinosaurs evolved from these reptiles and were themselves diapsids. During the Jurassic and Cretaceous Periods the dinosaurs ruled the earth. Both plants and animals reached giant proportions during the Mesozoic. During the 180 million years of the Era, reptiles lived on land, in seas, and in the air.

Cambrian Period The Cambrian period, part of the Paleozoic era, produced the most intense burst of evolution ever known. The Cambrian Explosion saw an incredible diversity of life emerge, including many major animal groups alive today.ore than 17,000 species are known to have survived until the mega-extinction that ended the Permian period 251 million years ago. A predator of the Cambrian was the giant, shrimplike Anomalocaris, which trapped its prey in fearsome mouthparts lined with hooks.

The Triassic Period: Reptiles Inherit The Earth The Mesozoic Era is divided into three periods: the Triassic Period, the Jurassic Period, , and the Cretaceous Period. The Triassic began around 248 million years ago, after the mass extinction that brought an end to the Permian Period.It lasted about 42 million years.he Triassic Period is the first period of the Mesozoic Era. The great extinction at the end of the Permian period had brought the end to 90% of the living species on Earth. The Triassic was a time of growing new species to repopulate the planet. A New Era. This time was the beginning of a new era, the Mesozoic Era.

Mesozoic Era Paleobiology Mesozoic Era (245 to 65 mya). One of the most striking events in the Mesozoic Era was the rise to dominance of dinosaurs in terrestrial ecosystems. The Mesozoic lasted from 245 to 65 million years ago, and is divided into three periods. The Mesozoic, which derives its name from the Greek with a rough meaning of middle animals, began after the Permian extinction and ended with the Cretaceous extinction.

ERA OF THE DINOSAURS During the Mesozoic Era, the Earth’s landmasses changed dramatically, new seas were formed, and plants and animals evolved. Geological timescale Geologists divide Earth’s long history into a series of time zones, from the origin of the planet, about 4,600 million years ago, right up to the present day.

Paleozoic Era Flight was first achieved also during the Carboniferous Period as insects evolved wings. The Permian extinction, at the end of the Paleozoic Era, eliminated such major invertebrate groups as the blastoids (an extinct group of echinoderms related to the modern starfish and sea lilies), fusulinids, and trilobites.

Reptile Archosaurs developed into the well-known dinosaurs and pterosaurs, as well as the ancestors of crocodiles. Since reptiles, first rauisuchians and then dinosaurs, dominated the Mesozoic era, the interval is popularly known as the Age of Reptiles.

Mosasaur Mosasaurs probably evolved from an extinct group of aquatic lizards known as aigialosaurs in the Early Cretaceous. During the last 20 million years of the Cretaceous period (Turonian-Maastrichtian ages), with the extinction of the ichthyosaurs and pliosaurs, mosasaurs became the dominant marine predators.

- The era began after the Permian-Triassic mass extinction and ended with the Cretaceous-Paleogene mass extinction. The Mesozoic is perhaps best known for being the age of the dinosaurs, the era in which dinosaurs arose and came to dominate the Earth. Flowering plants also appeared towards the end of this era. At this time mammals and birds first evolved, but would not diversify that much until the Cenozoic Era. The Mesozoic was much warmer, and the supercontinent of Pangea separated and was drifting apart to form the modern continents.
