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.
Coptic Cairo
There is evidence of settlement in the area as early as the 6th century BC, when Persians built a fort on the Nile, north of Memphis. The Persians also built a canal from the Nile (at Fustat) to the Red Sea. The Persian settlement was called Babylon, reminiscent of the ancient city along the Euphrates, and it gained importance while the nearby city of Memphis declined, as did Heliopolis. During the Ptolemaic period, Babylon and its people were mostly forgotten.
