The bone, a humerus -- or upper arm bone -- came from Grăunceanu, a rich fossil deposit in the Olteţ River Valley of Romania. For nearly a decade, Terhune and an international team of researchers have focused their attention on Grăunceanu and other sites of the Olteţ. These sites, initially discovered because of landslides during the 1960s, have produced fossils from a wide variety of animal species, including a large terrestrial monkey, short-necked giraffe, rhinos and saber-toothed cats, in addition to the new pangolin species.
