At the end of the Triassic period 200 million years ago, there was a mass-extinction event that caused the extinction of more than half of all living species. It was this extinction event that allowed dinosaurs to become the dominant species for the next

he lecturer disputes the author's suggested theory that an abrupt decline in sea water level caused a massive extinction in the Triassic period. She provides several concrete reasons to cast doubt about the author's claims.

First, according to the author a significant decrease in sea water level caused a massive extinction of living species. However, the lecturer finds this idea debatable. she asserts that a gradual decrease in sea water level does not cause a massive killing because animals living in shallow water can adapt to the change in sea water level.

Second, the lecturer contradicts the fallacy of the passage that a decrease in temperature is the reason behind this massive killing. She contends that a decrease in temperature could cause massive killing if it was for a long period of time. However, The lecturer points out that theoretically speaking the rain may have washed all the sulfur dioxide in the air. Thus, the elevation in temperature was last for only a short period.

Finally, the lecturer argues that no crater was discovered at the site of the collision. The author argues that a debris which block the sun light may have caused this massive extinction. However, the lecturer also disputes this point. She argues that the only crater discovered was 12 million years before the Triassic period. Thus, it is very unlikely that an asteroid collision may have caused this problem.
