Why are assemblages of fossils seen in successive geological periods so different?

Sagot :

The assemblages of fossils seen in successive geological periods so different because of continental drift.

During one or more geologic periods, continents moved horizontally at a huge scale in relation to one another and to the ocean basins. This is known as continental drift. The theory of plate tectonics, which integrates this idea, had this idea as a key antecedent.

The notion of the continents being massively moved has a long history. The importance of fossils is another significant piece of data supporting the Continental Drift theory. Numerous fossils have been discovered on various continents and in no other areas. The vast oceans separating these land masses serve as a kind of barrier for the transmission of fossils, proving that these continents were formerly connected. The Mesosaurus, Cynognathus, Lystrosaurus, and Glossopteris are four fossil specimens.
