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 causes of the massive Triassic extinction presented by the author. She provides several concrete reasons to cast doubt about the author's claims.

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

Second, the lecturer contradicts the fallacy of the passage that a decrease in temperature is the second reason behind this massive killing. She contends that a decrease in temperature could cause massive killing if it occurred over an extended period of time. However, The lecturer points that temperature elevations was only temporary event. it resides back to normal after the sulfur dioxide was washed away because of precipitation.

Finally, the author argues that this massive extinction occurred because of a meteoroids collision with the surface of the earth. Theoretically speaking, this collision cause a massive debris cloud to block sunlight. The lecturer also refutes this claim. She argues such a collision would cause a crater on the site of collision. However, astonishingly, no crater was found. Thus, it is very unlikely that this phenomena was caused by a meteoroids collision.
