Who hasn’t heard of Rodinia and Pangea?
According to plate tectonic reconstructions, the supercontinent Rodinia existed between 1.1 billion and 750 million years ago, in the Neoproterozoic Era. Rodinia has entered popular consciousness as one of the two great supercontinents of earth history.
Pangea existed during the late Paleozoic and early Mesozoic eras. It assembled from earlier continental units approximately 300 Ma, and it began to break apart about 200 Ma. It was the last supercontinent to have existed and the first to be reconstructed by geologists.
Over the 100 milion years Pangea existed, many species had fruitful times whereas others struggled. Permian–Triassic (P–Tr) extinction event marked the supercontinent history, colloquially known as the Great Dying occurred about 252 Ma (million years) ago, forming the boundary between the Permian and Triassic geologic periods.
The Jurassic world had its own history and its own glory days if we believe the story of the movie Ice Age. Some of us regret the fact that we didn’t live with those kind dinosaurs and those huge innocent mammoths in a lovely green earth, but God knew that we wouldn’t be able to co-op with the OTHERS. So we have to be thankful that we are able to know the past and to enjoy this “peaceful” earth.
