‘Dinosaurs Among Us’ at American Museum of Natural History, Selected by Mark Dion

Had it hatched, this remarkable fossil embryo of an Oviraptorosaur would have grown into a type of theropod dinosaur. Its head is tucked toward its knees, a position found in embryos today. This dinosaur embryo, a cast of which is in the exhibition, is the first ever found in which the bones were still in place. It often goes by the nickname Baby Louie.
