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.
Ras Matbakh
During the first large-scale archaeological expedition of Qatar in the 20th century, the Danish Mission, active from 1956 to 1964, made discoveries at Ras Matbakh. The area was first introduced to archaeologists Hans Jørgen Madsen and Jens Aarup Jensen in November 1961 by Ahmed bin Jassim Al Thani, then-ruler of Al Khor. Arriving on 22 November, the two Danish archaeologists surveyed and wrote a report of the site on 23 November. They unearthed a green pot near the coastline containing long-decomposed human remains, likely those of an adult, as well as some animal bones. The Danes estimated that the pot could originate from 500–300 BC and stated it resembled the burial tradition and pottery design found in ancient Bahrain and Mesopotamia at that time. Thus, they postulated that it may have been a burial for a Bahraini or Mesopotamian sailor who passed away near the site.
