A Mass Extinction Can't Keep These Molluscs Down (2 of 3)

Caption

In the Guangxi Province, South China, sedimentary deposits dating about 1 million years after the Permian-Triassic extinction crisis provide a rich ammonite fauna made of ~30 distinct genera, illustrating the consequences of the non-delayed “explosive” diversification of these extinct cephalopod mollusks after the crisis. This image relates to an article that appeared in the August 28, 2009, issue of Science, published by AAAS. The study, by Dr. A. Brayard at CNRS in Dijon, France, and colleagues, was titled, "Good Genes and Good Luck: Ammonoid Diversity and the End-Permian Mass Extinction.”
