Approximately 135 million years ago, during the Early Cretaceous period, significant geological and biological developments occurred. This era saw the continued breakup of the supercontinent Pangaea, leading to the formation of new oceans and Coastlines. Dinosaurs were the dominant terrestrial vertebrates, and the first flowering plants (angiosperms) began to emerge, marking a crucial evolution in plant life. Additionally, various marine reptiles and ammonites thrived in the oceans during this time.
The Cretaceous Period.
the iron age happened about 2.5 million years ago. the iron age was followed by the stone age, which happened about 3 million years ago
The late Jurassic Period, some 165 million years ago.
iron age
North America has been moving northward from Africa for the last 200 to 130 million years ago.
what really happened to the dinosaurs million years ago is it a fact
There quite a bit of evolutionary changes that happened 5 millions years ago. Mammals were constantly changing and humans as we know them today are said to be only 2.4 million years old.
Dinosaurs died
1-1.8 million years ago was approximately 0.2-0.8 million years ago.
due to climate changes :)
Snakes appear to have evolved during the Cretaceous which lasted 135 - 65 Million years ago
16 million years ago approximately
