Dinosaurs were a diverse group of reptiles that dominated Earth for over 170 million years. During the Triassic Period, they evolved widely and suddenly extinct around 65 MYA. Evolution theory states that the sudden extinction of dinosaurs made the way for the rise the mammals. Today, this article will tell you about various dinosaur species that evolved in the Mesozoic Era.

List of Dinosaur Species

Dinosaur

Dinosaurs were reptiles. They are usually divided into Carnivorous and Herbivorous and lived on the Earth for about 245 million years. In Greek, the meaning of “dinos” is “fearfully great”, and “sources” means “lizard”. As per paleontologists, the greatest variety of dinosaurs has been found in the North American deserts and badlands of China and Argentina, in the form of fossils.

How many types of Dinosaurs are there?

It is nearly impossible to say how many types of dinosaurs were present. But paleontologists have discovered more than 1000 species and divided them into 900 genera of non-avian dinosaurs till now. It is estimated that there were almost 2468 species that dominated the Earth through the whole Mesozoic period.

Now to understand the important species of dinosaurs, we need to know about with its three specific time periods.

Mesozoic Era – The Era of Dinosaur

The Mesozoic Era plays a major role in the Earth’s history. This era holds immense importace due to emergence and dominace of various reptile groups, specifically dinosaurs. The Mesozoic era consists with three major periods:

Periods Of Mesozoic Era
The Triassic Period (From 251.902 Mya to 201.4 Mya)	The Triassic Period, a geological timeframe for dating Earth’s events. The period began 251.9 MYA after the Permian Period. It concluded 201.3 MYA with the onset of the Jurassic Period. The period prolonged approximately 50.6 million years. Triassic period is named after the distinctive ‘Trias’ rock layers in north-western Europe. The Triassic is renowned for the emergence of dinosaurs and the appearance of the first true mammals. Pangea supercontinent defined the Triassic landscape. In this period, the red sandstones formed before the breakup of Pangea and can be found today in regions like North America and Africa, hosting rich Triassic fossils.
The Jurassic Period (From 201 Mya to 145 Mya)	The Jurassic Period was named after the Jura Mountain range, present in France Switzerland border. The period began around 201.3 MYA and ended around 145 MYA. It lasted 56 million years. It was the second longest period. Pangea broke into Laurasia in the north and Gondwana in the south in this period. The period followed a mass extinction that allowed dinosaurs to dominate the land Particularly sauropods like Diplodocus and Brachiosaurus, dominated this period. During the Jurassic period, Ornithischians emerged as a new group which were the one type of herbivorous dinosaurs. The dominant predators in the oceans were ichthyosaurs and plesiosaurs. The climate was warm and humid of the Jurassic period. The appearance of the first true birds was observed during the late Jurassic period. The period also marked the introduction of lizards and butterflies to the evolving Earth.
The Cretaceous Period (From 145 Mya to 66 Mya)	The Cretaceous Period spanned 145 million to 66 MYA. The period lasts for 79 million years. It was the longest epoch in the Mesozoic Era. It marked the third and final period in the Mesozoic Era which preceded the Paleogene Period. Laurasia and Gondwana continued to drift apart during this period to configure the modern landscape of the continents by the end of this period. The “Cretaceous” name came from the Latin word “creta”. It means the chalk layer formed in this period in Western Europe. Flowering plants like grasses, figs, planes, and magnolias were first seen in this period. Tyrannosaurus Rex and Velociraptor majorly dominated this period. The Cretaceous Period experienced the mass extinction which resulted the extinction of 70% of all species.
