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.

The instrument was first described by Athanasius Kircher in his 1650 work "Musurgia Universalis", though the lack of an image may have left doubt in the minds of some writers. ("The New York Times", for example, has carried an article claiming he described the instrument, and another stating he did not describe it in "Musurgia Universalis".). His description appears in Book 6, Part 4, Chapter 1, under the heading "Corollaria," (emphasis added):
