Fossil mammal R. robustus with dinosaur remains in its stomach

VIEW THE DINO-EATING MAMMAL FOSSIL AND MODELS NOW ON DISPLAY FOR THE FIRST TIME!

Beginning on Saturday, February 19, 2005, an exciting new paleontological find—a 130-million-year-old mammal fossil that also remarkably preserved the animal's last meal, a juvenile Psittacosaurus dinosaur—will be on public view at the American Museum of Natural History for a limited time. Discovered in China, this fossil, of an opossum-sized mammal called Repenomamus robustus, is the first direct evidence that some primitive mammals fed on small dinosaurs. Also on view are a life-size, fleshed-out model of Repenomamus giganticus—another fierce prehistoric mammal that was a close, larger relative of the dinosaur-eating mammal—and a model of the baby psittacosaur, a parrot-beaked herbivorous dinosaur. Both models offer visitors a preview of the upcoming exhibition, Dinosaurs: Ancient Fossils, New Discoveries, which opens at the Museum on May 14, 2005.
