Plant Insect Interactions of Ancient Times

Researchers are examining fossils from Patagonia and three sites in North America to gain insight into the historic biodiversity of the regions. Insect fossils are rarely found. By studying the damage caused by insects on the more abundant plant fossils, researchers are able to evaluate the type and level of insect feeding in prehistoric times. Life in Patagonia is among the most varied on the planet. The research shows that the region's biodiversity exceeded that of the other research sites as long as 52 million years ago.
