The short and the long of the Siberian Traps

10 February 2012

A new paper has suggested the Siberian Traps caused a long drawn out mass extinction at the Permian/Triassic boundary – described as a 'mass dying event' by some geologists as a result of so many species becoming extinct – to be replaced during the Triassic by new species that appear to have expanded relatively quickly. However, back in November the timeline of the event was much quicker – see http://web.mit.edu/newsoffice/2011/mass-extinction-1118.html where it is said it took place in the blink of an eye in geological time, a mere 20,000 years. Obviously the problem is that catastrophism of any kind is not recognised and the chronology is based on geochronology, specifically how long it took various sedimentary layers to be created.
