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 pebble
The pebble is interesting in that it was found some distance from any possible natural source, associated with the bones of "Australopithecus africanus" in a cave in Makapansgat, South Africa. Though it is definitely not a manufactured object, it has been suggested that some australopithecine might have recognized it as a symbolic face, in possibly the earliest example of symbolic thinking or aesthetic sense in the human heritage, and brought the pebble back to the cave. This would make it a candidate for the oldest known manuport.
