Discovery and species
In 1859 coal mine administrator Pawlowitsch notified the University of Vienna that some fossils had been found in the Gute Hoffnung mine at Muthmannsdorf in Austria. A team headed by geologists Eduard Suess and Ferdinand Stoliczka subsequently uncovered numerous bones of several species, among them those of a euornithopod dinosaur. Stored at the university museum, the finds remained undescribed until they were studied by Emanuel Bunzel from 1870 onwards.[1] Bunzel in 1871 referred PIUW 2349/3 (identified by him as a thoracal rib) to Lacerta sp.[2] In 1881 Harry Govier Seeley recognized PIUW 2349/3 as a femur belonging to Dinosauria and erected the new genus and species Ornithomerus gracilis for it.[3] The generic name is derived from Greek ornithos, "bird", and meros, "shin". Norman and Weishampel (1990) and Norman (2004) listed Ornithomerus, along with Oligosaurus and Mochlodon, as a synonym of Rhabdodon.[4][5] However, Sachs and Hornung (2006) assigned Ornithomerus to Zalmoxes sp. along with the Mochlodon suessi holotype.[6]
The type specimen PIUW 2349/3 was found in the Grünbach Formation of the Gosau Group dating from the Lower Campanian, about 80 million years old.
