Fossils of the same type and same age have been found on different continents. If we were to put South America and Africa together, these fossils would even be in the same area! What does this tell us? How could this happen? Can some one help me plz

there have been several cases where fossils of the same type and age where found on different continents.

For example:-

"The Mesosaurus" which is an extinct genus of reptile from the Early Permian and was found in the continents of southern Africa and South America.

This seems to point to the fact that once all the continents were togethe, and they are now separate due to the Continental drift. ( the theory that states that all the continents were earlier one big form of landmass, but they have moved away from each other thus appearing to have "drifted" across the ocean bed."

But again these are all just theories and speculations but findings like these strengthen them and make people believe in these theories. They haven't exactly been confirmed. Like the evolution theory.

i hope this helps.

have a great day ahead :)
