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.
Prehistoric Europe
This period extends from c. 2500 BC to c. 1800 or 1700 BC (depending on the region). The dates are general for the whole of Europe, and the Aegean area is already fully in the Bronze Age. ca. 2500 BC the new Catacomb culture (proto-Cimmerians?), whose origins are obscure but who are also Indo-Europeans, displaces the Yamna peoples in the regions north and east of the Black Sea, confining them to their original area east of the Volga. The Catacomb culture is the first to introduce corded pottery decorations into the steppes and shows a profuse use of the polished battle axe, providing a link to the West. Parallels with the Afanasevo culture, including provoked cranial deformations, provide a link to the East. Some of these infiltrate Poland and may have played a significant but unclear role in the transformation of the culture of the Globular Amphorae into the new Corded Ware culture.
