"The dramatic explosion of flowering plant species that occurred about 100 million years ago was thought to have been good news for evolving mammals, providing them with new options for food and habitat. But research by geologists at Indiana University Bloomington suggests that wasn't necessarily the case. In a study published in the journal Proceedings of the Royal Society B, David Grossnickle and P. David Polly present evidence that mammal varieties declined during the great angiosperm radiation of the mid-Cretaceous, a time when a great diversity of flowering plants appears in the fossil record. Grossnickle, a former high school biology teacher, conducted the research for a master's degree in geology from IU; he is now a doctoral student at the University of Chicago. Polly is a professor in the Department of Geological Sciences in the College of Arts and Sciences…"
