Pangaea broke up approximately 180 million years ago.
Continents have taken less than 100 million years to drift to their current positions.
Scientific ideas are not shared or discussed with others in the scientific community.
Scientific ideas are never met with skepticism.
Scientific ideas are subject to change with new evidence.
Scientific ideas are facts.
Substantial evidence exists that supports the Pangaea did exist and eventually broke up into drifting continents.
The break up of Pangaea is questionable.
Antarctica has always been in a southern position and very cold.
Glossopteris seeds can easily be dispersed over large masses of water.
Divergent plate boundary
The continent will NOT move

The continents fit together like a puzzle
Messosaurus fossils appear in South America and Africa in relatively the same area
The Tethys Sea was shallow and warm.
Glossopteris fossils were discovered in all areas of the supercontinent.
Mesosaurus lived in South America, India, Africa and Antarctica
Glossopteris appeared in the fossil records of the entire continent
Mesosaurus became extinct before the continent broke up.
Both Glossopteris and Mesosaurus are trace fossils.
In the middle.
Found close to the rift zone.
Found far from the mid ocean ridges.
It could not explain how or why the continents were drifting.
He could not provide evidence for the continental drift.
