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.
Lake Athapapuskow
The area has been inhabited since prehistoric times. Archaeological digs at Bakers Narrows revealed pottery, arrowheads, and other artifacts which were at least 2,500 years old and indicated regular habitation by the "Shield Archaic Culture", who hunted caribou in the area as far back as 7000 years ago. They were eventually supplanted by the Woodland Cree who were nomadic hunters in this region. The site of Cranberry Portage has been the primary route linking the Grass River and Saskatchewan River watersheds for at least 2,000 years. 
Many of the most important explorers in Canadian history travelled through Lake Athapapuskow. In 1763, Hudson's Bay Company explorers Joseph Smith and Isaac Batt, guided by Cree leader Meesinkeeshick, became the first European recorded to visit Lake Athapapuskow; Smith died on the return journey to York Factory. Ten years later, the Governor of Churchill sent the fur trader Joseph Hansom, also guided by Cree, inland to extend the reach of the HBC. He paddled from Lake Kississing down the Pineroot River, reaching Lake Athapapuskow. In 1774, the explorer Samuel Hearne with 2 Englishmen, 6 native guides, and 5 canoes, laden with "180 lbs. Brazil Tobacco, 130 lbs. Powder, 100 wt. of Shott & Ball, 6 Gallns Brandy and some other trifling articles of Trading goods" paddled up the Grass River to Cranberry Portage and into Lake Athapapuskow en route to establishing Cumberland House. This route became an important part of the North American fur trade, known as the "Upper Tract". It was abandoned by 1800 in favour of the Nelson River and Hayes River routes. In 1794, the fur-trader and cartographer David Thompson, surveyed the lake.
