I wonder what it was that departed as a result of the event that so
"emptied the world"? After all, rudists were gone before, ammonites had
suffered a Cretaceous-long decline. Mosasaurs and other big reptillian
marine animals had all but gone before. I need to read this study...but
couldn't resist the questions.
