A number of scientists believe that the Permian extinction was caused by huge volcanic lava flows (from the Siberian traps) that may have caused low oxygen concentrations compared to the high oxygen levels in the Permian. Does this low oxygen level after the Permian extinction make it likely that dinosaurs, especially large ones, did not evolve immediately after the Permian extinction (252 million years ago)? Why or why not?
