Before learning about dinosaurs, you need to know about their age.
Mesozoic Ira
•The Mesozoic Ira is a period of about 25 million to 65 million years.
•The Mesozoic era is mainly classified into 3 categories
1.Triassic Age
2.Jurassic Age
3.Cretaceous Age
TRIASSIC AGE
The Triassic Age is the first period of the Mesozoic era. This period is estimated to be between 251 million and 199 million years ago.
JURASSIC AGE
The Jurassic Age is the second age of the Mesozoic period. This occurred 199.6 to 145.5 million years ago, following the Triassic Period and preceding the Cretaceous Period.
CRETACEOUS AGE
The Cretaceous Period was the last and longest segment of the Mesozoic Era. It lasted approximately 79 million years, from the minor extinction event that closed the Jurassic Period about 145.5 million years ago to the Cretaceous-Paleogene (K-Pg) extinction event dated at 65.5 millian years ago.
The Mesozoic era is a combination of these three. It is during this time that dinosaurs are born and die on Earth.
The word dinosaur is a Greek word. It is derived from the words Dino and Ceres. The word dinosaur was first coined in 1842 by Richard Owen, a paleontologist.
Dinos in Greek means terrible Ceres means lizard. I.e. the frightening lizard. It is divided into Saurischia and Ornithisia.
SAURISCHIA
The Thunderbolt of this section is almost a lizard structure. Hence they are called Saurischia.These are also called lizard hipped.
ORNITHISCHIA
If you take their skeletons, their thunderbolt is like a bird's thunderbolt.
When we think of dinosaurs, we think of them as terrifyingly large creatures, but dinosaurs are not only large, but Mussaurus is a smaller dinosaur than a mouse. Argentina Cirrus is the largest dinosaur ever found in Argentina. It is about 100 feet long and 50 feet high and belongs to the genus Soropots.
Although there are many arguments about the end of dinosaurs, the most plausible is the claim that they were 'destroyed by meteor showers or volcanic erupt
