New paper about the Permian-Triassic boundary is South Africa
has been published in the March 2009 issue of “Geology”. It
argues that the so-called “event bed” that allegedly marks the
Permian-Triassic boundary neither marks it nor can be used to
interpreted paleoenvironmental changes that occurred during
the Permian-Triassic extinction event. The paper is:
