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.
Batadombalena
The Batadombalena archaeological site contains evidence of habitation from as early as 8,000 years BCE and is one of the sites whose discoveries support the "Out of Africa" hypothesis, according to Professor Paul Mellars, a Cambridge University archaeologist. Among the evidence of Balangoda Man he unearthed at the site were stone tools that are interpreted as arrow - or spearheads and carefully shaped and perforated beads made from ostrich eggshell fragments. One particular piece of an ostrich eggshell, incised with a distinctive criss-cross motif, has also been discovered.
