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.
Makapansgat
Makapansgat Valley has been described as having one of the greatest palaeontological records of human evolution in the world. Collecting at the site began in 1925, when a local school teacher, Wilfred Eitzman, was attracted by the activities of limeworkers. Some fossil material was sent to Raymond Dart, who initiated a systematic investigation in 1947. Eitzman also discovered the so-called "Makapansgat pebble" associated with the bones. Ca. 3,000,000 BCE, the pebble is shaped naturally to resemble a human face, it is thought to have been found by an Australopithecus and carried from its source into the Makapansgat cave. It has been suggested that this pebble represents the earliest known example of symbolic thinking of early hominids.
