You Are a Paleontologist Studying the Fossil Marine Fauna Immediately

question 31

Essay

You are a paleontologist studying the fossil marine fauna immediately after the K-Pg mass extinction. You find ammonite fossils in the post-K-Pg layer even though ammonites are believed to have vanished in the K-Pg extinction. You submit your sensational findings to a journal, but one of the reviewers questions your claim of ammonite survival. He points to the fact that your ammonite fossil was found in rock that shows extensive burrowing activity by benthic organisms. Why does the reviewer question your conclusion?
