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.
Kotumsar Cave
The cave has been known since the British era of India, but it was not taken seriously until the 1950s when the geography professor Dr. Shankar Tiwari visited the cave and attempted to explore its chambers with limited resources and equipment. The cave was first systematically mapped in the 1980s by Dr. Jayant Biswas (then a PhD scholar), guided by a Romanian caver. The map was first published in Biswas's PhD dissertation in 1990, and in 1992 by him in the internationally recognized publication of the National Speleological Society .
