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.

Part 6: The Gulf Between Reptiles and Mammals There is a continuum of fossil forms from basically primitive reptiles, to primitive synapsid reptiles, to advanced mammal-like reptiles, to primitive reptile-like mammals, to advanced mammals of the kind that survive today.ll mammals, living or fossil, have a single bone, the dentary, on each side of the lower jaw, and all mammals, living or fossil, have three auditory ossicles or ear bones, the malleus, incus, and stapes.

- Dinosaurs are reptiles that walked the earth a long time ago. There are many different types of dinosaurs that lived during different times. Click the speaker to hear a reading of this page! Dinosaurs existed millions of years ago. The three time periods Dinosaurs walked the Earth from youngest to oldest are called the Paleozoic era, Mesozoic era, and the Cenozoic Era. The Mesozoic Era is divided into three periods; the Triassic, Jurassic, Cretaceous periods.

Difference Between Reptile and Amphibian Difference Between Reptile and Amphibian. Reptile and amphibian are two of the most closely related class of creatures as members of both families are cold blooded and are vertebrates, meaning they have backbones. Furthermore, except crocodiles and its relatives, almost all reptiles and amphibians have a three-chambered heart.

- 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.

- Dinosaurs first appeared in the Triassic period about 230 million  years ago. Non-avian dinosaurs roamed the earth until about 65  million years ago and then were wiped out,… most like by the impact  of an asteroid or comet. Birds, which are now classified with the  dinosaurs, continue to live to this day. Dinosaurs lived on earth for over 160 million years. They were the dominant terrestrial vertebrates from the late Triassic period (around 230 million years ago) to the end of the Cretaceous period (around 65 million years ago).

Reptile Early in the period, the modern reptiles, or crown-group reptiles, evolved and split into two main lineages: the Archosauromorpha (forebears of turtles, crocodiles, and dinosaurs) and the Lepidosauromorpha (predecessors of modern lizards and tuataras).

- The earliest dinosaurs and mammals date back to the late Triassic period, about 225 million years ago. Most of the first Triassic dinosaurs were small and quick meat-eaters that walked on their hind legs. By the end of the Triassic period (about 20 million years ago), larger prosauropods (20-foot-long plant-eating dinosaurs) were beginning to appear. The Jurassic period began about 200 million years ago and lasted about 55 million years. Many new types of dinosaurs, mammals, and reptiles emerged during the Jurassic, including the plated dinosaurs and the sauropods  heavy, long-necked dinosaurs that walked on four legs.

Dinosaurs Dinosaurs were land animals that lived in almost all parts of the world, from tropical regions to deserts. They came in many different sizes and had different body shapes. Some were huge creatures, up to 40 meters long and a hundred tons in weight. Others were as small as a chicken. Most dinosaurs had a scaly skin with no hair on their bodies. Although we often think dinosaurs were grey, dull creatures, experts think that some of them could have been really colorful.

reptilenoun  [ C] But they also eat small animals, other reptiles – and other alligators! Crocodilians (crocodiles and alligators) are reptiles. Reptiles are animals that come from eggs, like birds. Reptiles are cold-blooded animals – they need the sun to stay warm. There are many insects that look like flowers and plants, but some reptiles do, too. Turtles and tortoises are two amazing, and quite different, species of reptile.

Dinosaurs, Birds, and Change The Triassic Period – roughly 251 to 199 million years ago. Around 245 million years ago the first dinosaurs appeared. This was during what geologists call the Triassic Period – the first period of the Mesozoic Era. Dinosaurs were reptiles and they had been preceded for millions of years by other reptiles on land. Conditions had allowed the survival of the larger reptiles, whose size helped them survive.

Difference between Reptiles and Amphibians They are also vertebrates, i.e. they have backbones.
