A unique fossil assemblage from the Devonian of the Northwest Territories: A search for evolutionary missing links in the rise of fish
Principal Investigator: Miyashita, Tetsuto
Licensed Year(s): 2023
Summary: This licence has been issued for the scientific research application No. 5549. Through this field project, the hope is to accomplish two goals: 1) to fill in a major gap in, and transform knowledge of early vertebrate evolution through the analysis of new fossils from the Anderson River locality, which represent a poorly known interval of the geological time; and 2) to establish a line of publi...

Evolution of Arctic Lampreys
Principal Investigator: Renaud, Claude B.
Licensed Year(s): 2012
Summary: The purpose of this study is to know more about the lampreys of NWT. It is part of a larger scale study of lampreys of the genus Lethenteron across the northern hemisphere (Eurasia and North America). In the Northwest Territories (NWT) part of the study our objectives are: 1- To collect a total of about 30 larvae at least 60 mm in total length for each of the two species from localities where a...

Late Cretaceous Marine Fauna and Paleoenvironment at Lac des Bois, NT
Principal Investigator: Cumbaa, Stephen L
Licensed Year(s): 2010 2008 1997 1995
Summary: To discover fossil bones and teeth of new species of ancient fishes, and remains of other animals that shared the shallow waters of the Western Interior Seaway with them. This seaway covered the middle of North America, from the NWT to the Gulf of Mexico. The researchers are trying to learn more about the environment of this ancient seaway, and why it was a "hot spot" for fish evolution. The ...

Jurassic and Cretaceous ichthyosaurs diversity in Northern Canada
Principal Investigator: Maxwell, Erin E
Licensed Year(s): 2009 2008
Summary: This licence is being issued for the scientific research application no. 1011. The goals of this research are to 1) collect and identify invertebrate fossils to correctly date the rocks the historic marine reptile fossils were collected from; and 2) to collect and identify any new vertebrate fossils found, in order to improve our knowledge of the diversity and evolution of Mesozoic marine repti...

The biogeography and ecology of deepwater sculpin (Myoxocephalus thompsoni): conservation of a glacial relict
Principal Investigator: Sheldon, Tom
Licensed Year(s): 2004
Summary: The deepwater sculpin is a small species of fish found only in the deepest lakes in Canada. Its closest relative is the marine fourhorn sculpin which is distributed in shallow marine waters of the arctic North American coast. To resolve the issue of orig...

Molecular analysis of evolutionary change in stickleback populations
Principal Investigator: Kingsley, David M.
Licensed Year(s): 2010 2008 2007 2005 2004 2002 2001 2000
Summary: The research goal is to determine whether the same genes control similar skeletal change in different populations and species. Stickleback fish are ideal subjects for this study because different freshwater populations show morphological differences in s...

New ischnacanthid acanthodians from the Lower Devonian of the Mackenzie Mountains, NT, Canada
Principal Investigator: Hermus, Chelsea
Licensed Year(s): 2002
Summary: The main objective of the project is to collect fossils of two specific groups of early fishes (acanthodians and heterostracans) to supplement specimens already collected for research projects at the University of Alberta. The field party plans to journe...

Role of Climate and Sea Change on Early Cambrian Evolution
Principal Investigator: Pope, Michael
Licensed Year(s): 2003 2002 2001
Summary: The research team will fly to Norman Wells by commercial airline, and then travel to the field by helicopter or Twin Otter. Travel in the field will be by canoe, or on foot. Field camps will be low impact, and will be occupied for less than 14 days. All human waste will be buried, and all non-burnable garbage will be packed out. The research team will measure, describe and sample the Early Camb...

Distribution of Late (Frasnian) Devonian Crinoids in the Hay River and Mackenzie River Regions of the Northwest Territories, Canada
Principal Investigator: McIntosh, George
Licensed Year(s): 2000
Summary: This research involves how groups of marine invertebrate fossils, crinoids evolved over a 6 million year interval designated as the Frasnian Stage. The researcher will study the rock exposures along the Mackenzie Highway between Hay River/Enterprise and Fort Simpson. The fossils to be collected rarely exceed 3 cm and collecting will be restricted to weathered surfaces composed of loose material. ...

Collection of Silurian fishes and trilobites and articulated remains of Devonian chondrichthyans and other fishes from the Mackenzie Mountains, N.W.T.
Principal Investigator: Wilson, Mark V.H.
Licensed Year(s): 2013 1998 1996 1990
Summary: The objectives of the research are 1) to collect remains of Silurian and Devonian fishes, and 2) to collect remains of Silurian trilobites. Activities are limited to travel, residence at camp locations and collection of fossils. Helicopters will be used to access camp sites. We plan to land at Avalanche Lake on July 15, spending 6 days collecting fossils at Avalanche Lake, followed by one day of t...
