Man On The Hill (MOTH)
The Man on the Hill (MOTH) locality of northwestern Canada has fossils that are very well preserved and have had a profound impact on the understanding of vertebrate evolution. The geology of the MOTH locality consists of fine, alternating laminae of light grey argillaceous limestone, or calcareous shale, and dark grey silt to sand-rich calcareous shale, as observed in thin section, and the characterization of the lithology for the vertebrate-bearing strata as an interlaminated argillaceous limestone and calcareous shale. The abundance of cryptic trace fossils and the presence of pyrite suggest that the intra-shelf topographic sag at MOTH had restricted circulation and was generally hypoxic (Zorn et al. 2005). The MOTH locality (62°32' N, 127°45' W) is located in the Central Mackenzie Mountains, approximately 70 km northeast of Tungsten, Northwest Territories The townsite of Tungsten (shown as Cantung on some maps) is located at Cantung Mine in the Northwest Territories.

Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces an ...

Tungsten, Northwest Territories
The townsite of Tungsten (shown as Cantung on some maps) is located at Cantung Mine in the Northwest Territories. It is accessible from Watson Lake, Yukon via the Nahanni Range Road History Tungsten was built in 1961 and the tungsten mine went into operation in 1962 as a large open-pit mine in the Mackenzie Mountains. It originally consisted of several small bungalow houses. Total population of Tungsten during the 1960s was approximately 120 persons, including about 27 families. In 1968 families were housed in 28 units (single and duplex housing). Because of extremely good wages and benefits, turnover rates for the entire operation were quite low. Families benefited from the K-8 Grade school, and later a K-9 system. During the summer months, because of the open pit operation, manpower and townsite population grew to 160. In the mid-1970s, the townsite expanded to include a trailer court, three condominiums, bunkhouse trailers, and in 1982, a modern recreation complex. An 80 ...

Nááts'ihch'oh National Park Reserve
Náátsʼihchʼoh National Park Reserve ( ) is a Canadian National Parks of Canada, national park reserve encompassing parts of the South Nahanni River watershed in the Northwest Territories. The name means "stands like a porcupine" in the Chipewyan language, Dene language. The national park reserve covers an area of , protecting the Sahtu (electoral district), Sahtú Settlement Area of the upper South Nahanni River watershed, adjoining Nahanni National Park Reserve. The two areas are to be managed separately, similar to Banff National Park, Banff and Jasper National Parks which are also side by side. The South Nahanni watershed is home to several endangered species, including grizzly bears and boreal woodland caribou. The area is also known for its western moose, moose, Dall sheep and the northernmost population of mountain goats in Canada. Features 'Náátsʼihchʼoh National Park Reserve is within the Mackenzie Mountains. The park takes its name from Náátsʼįhchʼoh (Mount W ...

Fossils Of Canada
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the absolut ...
