Intro to Palaeontology - Thursday, 1st Period
This week Cutter did have a lecture prepared, even after spending a few days as a child over the weekend, “so this week we’re going to continue on with our coverage of extinction periods,” he began as he started to hand out the usual amount of notes that he had prepared.
“Last time we covered the Ordervician - Silurian Extinction and the Devonian Mass Extinction,” Cutter said once the notes had been handed out, “we’re going to cover just one mass extinction event this week and that is one we’ve touched upon earlier this semester and that is the Permian-Triassic Extinction,”
“Since this is considered to be one of the worst mass extinction event that the Earth has currently faced, I thought it should have it’s own lecture,” he explained, “this extinction event is also known as the Great Dying and it happened 252 million years ago and this caused the extinction over 95 percent of marine and 70 percent of terrestrial species,”
“According to fossil evidence, it is believed that there were large coniferous forests in modern day Europe and like with a number of plants that didn’t survive the extinction event and this is also one of the rare cases where a mass extinction of insects have occurred. One of the few species that weren’t as severely impacted by this extinction event were fungi and this was because there was plentiful dead animal and plant material for them,”
“There are a few different hypothesis on what caused this extinction event and that there were a number of environmental changes that led to this, these include the temperate increasing so that marine life living in shallow waters couldn’t survive, that there was significant changes in the carbon cycle and that this had an impact in regards to the biological cycle during this time following the eruption of the Siberian flood basalts,”
“It is also believed that the environmental changes on land occurred before the impact started to reach the oceans and that is why there is a considerable difference in the impact to the marine and terrestrial species,”
“Now I believe a couple of weeks ago I asked you to do a report into a mass extinction event that we’ve covered, if you hadn’t already done so I’ll extend the report until next week and we’ll present it then,”
