Fossil mollusks in Maryland outcrop


The fossil mollusks in this Maryland outcrop lived approximately 15 million years ago. UChicago paleontologists Andrew Z. Krug and David Jablonski analyzed the fossil record of mollusks for the last 200 million years, finding that mass extinctions don't just remove evolutionary lineages, they exert a long-term influence on evolutionary rates among the survivors.
