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.
As the reading mentions, at the end of the Triassic period 200 million years ago, there was a mass-extinction event that eliminated too many of the living species. Still the cause of this massive extinction is uncovered. The writer elaborates several possible explanation to this phenomena. However, the professor states that these explanation may be plausible but they are not strongly supported to cause the mass-extinction.
First theory declares that the decline of sea levels causes the habitats in the shallow areas to be destroyed and have a profound effect on food chains worldwide. The speaker rebuts this idea and elaborates that the habitats in coastal areas are very adoptive and the slow change of sea levels could not cause a massive destruction only if the change of sea level was so sudden.
Second idea states that massive climate cooling could have devastated many species. However, the lecturor explains that although SO2 could cause climate cooling, it is unlikely to be cause of extinction.Because this phenomena happend in a short amount of time, yet the traces of SO2 is still in the atmosphere.
The last theory involves an astroid strike that colided with earth and the displaced debris is thrown uo into the atmosphere where it can block out sunlight for enough amount of time to eradicate many of the species.To contrast the professor states that an enormous asteroid must have left behind an crator but no such thing was found that happend in that period.
