Unit Type: Lithostratigraphic
Rank: Formation
Status: Formal
Usage: Currently in use

Age Justification: Pelecypods, cephalopods.
Province/Territory: Northwest Territories; Yukon Territory

Type Locality:
The valleys of the Kotaneelee and Petitot Rivers tributaries of the Liard River, ca. 60 deg 00' to 60 deg 15'N, 123 deg 00' to 124 deg 00'W.

It is 152 to 305 m (500 to 1,000 ft) thick. It extends over the lower part of the Dunedin River and the Liard River valleys from near the mouth of the Beaver River to the mouth of the Kotaneelee and in the lower part of the Petitot River valley.

Concretionary marine shale; sandstone and rare conglomerate.

It conformably overlies the Dunvegan Fm (described as Fort Nelson Fm which has subsequently been abandoned) and is gradationally overlain by the Wapiti Fm. The Kotaneelee is apparently equivalent to all or most of the Wapiabi Fm.
