Shocking evdience supporting the idea of a P/T (Permian/Triassic) impactor has made the news today (though this actually was discovered in 2003). A crater that spans 300 miles in diameter has been discovered lying beneath Antarctica's eastern glacial ice sheet....for the purposes of comparison, the famed K/T impactor crater at Chicxulub is 120 miles wide. If proven to be 251 million years old, this mega-monster crater could very well have caused Earth's biggest mass extinction. The P/T extinction wiped out 95% of all life on Earth and a massive meteor could be to blame.

Some have suggested that this impact is what caused the Siberian Trapps to erupt as much magma/lava as it did...enough to cover the whole planet to a depth of 10ft.

It is interesting to note that just like at the K/T boundry, the massive impact and massive volcanic activity is on almost exactly opposite sides of the planet...as if the force from the impact traveled through the planet and agitated the magma plume enough to cause violent eruptions.

Note that the Chicxulub crater and Deccan Trapps are 170 longitude apart and at nearly identical lattitudes. By the same tolken, the potential P/T impactor crater and Siberian Trapps are within 10 longitude and about 10 to 15 lattitude apart (in relation to their respective poles). Coincidence?...maybe, but I think there may be more than just a connection here.
