Dinosaurs first appeared around 230 million years ago, during the Triassic period. This was part of the Mesozoic era, which covered almost all of dinosaur existence.
Fish, reptiles, and amphibians, originated in that order during the Paleozoic era.
They evolved from amphibians during the Carboniferous Period.
The correct order in which vertebrates evolved is fish, amphibians, reptiles, birds, and then mammals. Fish were the first vertebrates to appear, followed by amphibians that adapted to life on land. Reptiles evolved next, leading to the development of birds and eventually mammals. Thus, the correct sequence is fish, amphibians, reptiles, birds, and mammals.
The term 'dinosaurs' refer to any of numerous extinct terrestrial reptiles of the Mesozoic era - ergo, they were not amphibians.
Reptiles have scales and Amphibians do not.
Amphibians do not have scales; reptiles do.
No. Birds and reptiles are separate from amphibians.
Reptiles first appeared during the Paleozoic Era, specifically the Carboniferous System of the Paleozoic Era. That was about 320 million years ago.
No. Reptiles and amphibians are two different orders and animals and amphibians cam first. Simply put, the first amphibians evolved from fish and the first reptiles evolved from amphibians.
No, dinosaurs first appeared in the Mesozoic era, specifically during the Triassic period. The Paleozoic era preceded the Mesozoic era and was home to a different group of animals, including early fish, amphibians, and reptiles.
