Apparently, according to different sources, fish seem to have been around since the first dinosaurs and before.
Fish, reptiles, and amphibians, originated in that order during the Paleozoic era.
Dinosaurs evolved first and then some dinosaurs evolved into birds. So all birds are technically dinosaurs.
Yes, there were! In fact, sharks were around even beforethe dinosaurs!
The first dinosaurs evolved from fishes and were no bigger than these days crocodiles.
Dinosaurs first evolved 231.4 million years ago in Pangaea. This was during the beginning of the Mesozoic era, in the Triassic period.
Bacteria, sponges, jellyfish, fish and amphibians.Life began in water.The bacteria evolved into sponge-like creatures and then eventually into jelly-like creatures.These jelly creatures over a course of millions of years evolved into fish. The fish evolved into amphibians (water creatures who can also walk on land). The amphibians evolved into the reptiles we know as dinosaurs.
No. Dinosaurs evolved from reptiles. Birds evolved from dinosaurs.
NO! Many scientists believe that dinosaurs evolved into modern day birds. In addition, some reptiles and fish were living with the dinosaurs, such as the crocodile, and have remained virtually unchanged.
Dinosaurs emerged first. Some dinosaurs were birds, but they didn't come until later.
Jawless Fish were first, then jawed fish, then fleshy finned, ray-finned and other modern jawed fish evolved, amphibians and sharks were evolving at about the same time, reptiles evolved from amphibians, mammals and birds were both evolving at about the same time( both from reptiles), dinosaurs were also evolving at this time and about 100 million years later the asteroid hit the Earth and Mammals started to takeover where dinosaurs had been and 200000 years ago we evolved.
Dinosaurs evolved before chickens .
Dinosaurs came before birds, because dinosaurs later on evolved into birds, therefore, making birds come along LATER then the dinosaurs. However dinosaurs were far from the first creatures on earth.
