David Krause searches for tiny fossil mammal teeth in northwestern Madagascar. Krause, a professor in the Department of Anatomical Sciences at SUNY Stony Brook, discovered many new fossils while on a National Science Foundation (NSF)-supported expedition in 1996 to Madagascar including the fossil skeleton of Majungasaurus crenatissimus, a 70 million-year-old meat-eating theropod dinosaur from the Late Cretaceous period. While on the expedition, Krause also found a group of fossil mammals known as gondwanatheres that have only been found elsewhere in South America and India. Based on this finding, Krause and colleagues came up with new theories about the plate tectonic history of the super-continent Gondwana, which was comprised of South America, Africa, Antarctica, India, and Australia, and Madagascar). Another of their findings is that dinosaurs could be cannibals. To learn more about the discovery, see the Stony Brook news story Stony Brook Paleontologist Reunites With 70-million-year-old Dinosaur From Madagascar, and the LiveScience article The Bizarre Creatures of Madagascar.
