Given what we know about the consequences of the break-up of Pangea, we can confirm that it is very likely that this will have contributed to the extinction of some dinosaurs.
What was Pangea?
- Pangea, in simple terms, was a supercontinent believed to have existed as the first form of land on Earth.
- It is believed that this supercontinent later broke up into the continents that we know today or similar precursors to them.
- There is a great deal of evidence to support this theory, ranging from geological findings to geographical similarities.
How can this affect dinosaur extinction?
- The break-up of Pangea is believed to have caused the extinction of some dinosaur species.
- The break-up of this continent would have caused the separated lands to have been exposed to vastly different environmental conditions.
- Some parts moved far north and south, and became frigid climates, while others became or remained tropical or humid.
- This is likely to have caused the extinction of the dinosaurs who were not suited to survive in such conditions and could not evolve in time.
Therefore, we can confirm that the break-up of Pangea led to the extinction of some dinosaurs due to the fact that once this event led to the formation of the distinct continents, each new section of land was exposed to vastly different climate conditions, leading to the extinction of dinosaurs not able to adapt in time.
