The Mesozoic Era The Age of Dinosaurs The Age of Dinosaurs. The Mesozoic Era begins where the upheavals of the Permian Extinctions end. A mass extinction at the end of the Permian Period had eliminated most of the species of life that had existed throughout the Paleozoic Era.

The Paleozoic Era The Paleozoic Era. The Paleozoic Era, meaning ancient life is the first of three eras that form a part of the Phanerozoic Eon, the other two periods being the Mesozoic and the Cenozoic. The Mesozoic is the age of the Dinosaurs and the Cenozoic is the era in which we now live. The Paleozoic Era spanned a longer period of time, from approximately 542 Ma to 251 Ma. Just as the Mesozoic is divided into periods (Triassic, Jurassic, and Cretaceous), the Paleozoic Era is also divided. It contains six different periods which are:

Cretaceous Period The Cretaceous period began at the end of the Jurassic period approximately 144 million years ago and extended longer than any period (79 ma) to approximately 65 million years ago. The word Cretaceous comes from the word for chalk and the geological remains do indeed contain heightened chalk deposits.

Geological time scale The Cretaceous, Jurassic and Triassic Periods are collectively referred to as the age of reptiles. The first flowering plants appeared near the beginning of the Cretaceous Period. Evidence suggests that a vast shallow sea invaded much of western North America, and the Atlantic and Gulf coastal regions during the Cretaceous Period.

- The Cretaceous Period. 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.

The Mesozoic Era Global paleogeographic reconstruction of the Earth in the late Cretaceous period 90 million years ago. (Courtesy Dr. Ron Blakey). The Mesozoic Era is the age of the dinosaurs and lasted almost 180 million years from approximately 250 to 65 million years ago. This era includes 3 well known periods called the Triassic, Jurassic, and Cretaceous periods. A mass-extinction marked the beginning and end of the Mesozoic Era. The event that caused the transition from the Paleozoic era to the Mesozoic era was the greatest extinction this earth has seen. This extinction wiped out about 95% of all marine life and 70% of land-life.

TRIASSIC Dinosaurs lived throughout the Mesozoic Era, which began 245 million years ago and lasted for 180 million years. It is sometimes called the Age of the Reptiles. The era is divided into three periods.45 to 208 million years ago. 1  During the Triassic period, all land on Earth existed as one enormous mass. 2  It was called Pangaea. 3  The supercontinent slowly began to break up during the Triassic Period.

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. English geologist John Phillips, the first person to create the global geologic timescale, first coined the term Mesozoic in the 1800s.

About dinosaurs Dinosaurs lived between 230 and 65 million years ago, in a time known as the Mesozoic Era. This was many millions of years before the first modern humans, Homo sapiens, appeared. Scientists divide the Mesozoic Era into three periods: the Triassic, Jurassic and Cretaceous. During this time, the land gradually split up from one huge continent into smaller ones. The associated changes in the climate and vegetation affected how dinosaurs evolved.

- Dinosaurs are a diverse group of reptiles of the clade Dinosauria that first appeared during the Triassic period. 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. They became the dominant terrestrial vertebrates after the Triassic–Jurassic extinction event 201 million years ago.

In what period did the dinosaurs appear? Answer by KidPrawn. Confidence votes 1.4K. The Mesozoic Era in the Triassic Period. Dinosaurs first appeared during the Triassic Period (250-230 million years ago) and were on the Earth through the Jurassic Period (200-145 million years ago) until the end of the Cretaceous Period (65 million years ago).This whole era is called the Mezozoic Era (250-65 million years ago).he dinosaurs died 65 million years ago, in the cretaceous period ,during the mesozoic era.

During what era and time period within that era did the first dinosaurs appear on the Earth? Report Abuse. Well, Evolutionary scientists will say that the era is called the Mesozoic. And the first time period in which dinosaurs evolved is the Triassic. However, these are fictitious time periods that they made up out of their imaginations. The Triassic, Jurassic, and Cretaceous are a bunch of bologna.

- 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.
