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 145 million years. We do not know exactly what happened that eliminated so many species in a relatively short period of time, but there are several possible explanations.
The article states that the reason for eliminated so many species in the Triassic period 200 million years ago has several possible explanations and provides three reasons for support. However, the professor explains that the theory may seem not only to be plausible but is it not an adequate explanation for such prodigious extinction and refutes each of the author's reasons.
First, the reading states that the mass extinction seems to be due to the profound effect of The destruction of coastal and shallow-ocean species making by the fluctuating of sea levels. The professor refutes this point by stating that being believed fluctuation of sea level has occurred at the end of the Triassic by scientists notwithstanding, animals and plants accustomed to this situation at a gradual level; Nonetheless, this happening requires more sudden activity at 200 million years ago.
Second, the article claims that the SO2 released by the volcanoes decreased global temperature and killed many species. However, the professor contends that global cooling because the so2 was in a short time, and the raining could prevent the accumulation of the so2 in the atmosphere; although the So2 is present in the atmosphere now, it might not to be a reason to extinction.
Third, the reading avers that the plants and many animals died; thereby, asteroid impact at the end of the Triassic period and blocking sunlight thereof. However, the professor opposed this point by declaring that the crater is dating shown this Asteroids and impact occurred 12 million earlier than those extinction times.
