The lecturer disputes the author's suggested theory about the causes of mass extinction in the Triassic period. She provides several concrete reasons to cast doubt about the author's claims.
First, according to the author the cause of massive species extinction was a decline in sea water level which killed so many species. However, the lecturer disputes this cause. she contends that an abrupt decline in sea water might cause this extinction, however, this was not the case. She states the the decline was only gradual. Thus, species which live in shallow water are able to adapt to this change.
Second, the lecturer contradicts the fallacy of the passage that the extreme cooling in weather is the reason for this extinction. according to the lecturer the release of sulfur dioxide after volcano eruption results in a serious decrease in temperature. However, the lecturer points out that this cooling in weather was only temporarily. A few years decline in temperature is unlikely to cause the killing of so many species.
Finally, the asteroid theory is also unlikely to be true because no crater was found in location which struck the earth. Theoretically speaking an asteroid cause a crater around the struck area, which did not really happen. According to the lecturer The only crater which struck the earth was 12 millions years before this event.
