Leaf fossils show severe end-Cretaceous plant extinction in southern Argentina
The asteroid impact 66 million years ago that ushered in a mass extinction and ended the dinosaurs also killed off many of the plants that they relied on for food. Fossil leaf assemblages from Patagonia, Argentina, suggest that vegetation in South Am.....»»
