Catopsbaatar
Catopsbaatar is a genus of multituberculate, an extinct order of rodent-like mammals. It lived in what is now Mongolia during the late Campanian age of the Late Cretaceous Period, about 72 million years ago. The first fossils were collected in the early 1970s, and the animal was named as a new species of the genus "Djadochtatherium " in 1974, "D. catopsaloides". The specific name refers to the animal's similarity to the genus "Catopsalis". The species was moved to the genus "Catopsalis" in 1979, and received its own genus ("Catopsbaatar", Greek and Mongolian for "visible hero") in 1994. Five skulls, one molar, and one skeleton with a skull are known; the latter is the genus' most complete specimen. "Catopsbaatar" was a member of the family Djadochtatheriidae.
Cathole Cave
The cave was used as a shelter by bands of Mesolithic hunters and as a Neolithic ossuary. During the first excavation of the cave in 1864, finds were made only from the Mesolithic to medieval periods. In his "The Proceedings of the Prehistoric Society vol.25 (1959), pp. 260–69", archaeologist Charles McBurney notes that "In the Post Glacial period the cave was much used by Mesolithic hunters"; a conclusion confirmed by John Campbell's excavation of 1977.
