[3] The name Lynx Formation continues to be used in areas where some or all of the subdivisions cannot be distinguished.

All of the formations in the Lynx Group include fossil trilobites and some contain the stromatolite Collenia.

[4] The Lynx Group is composed alternating zones of carbonate rocks, most of which are dolomitic, and shales.

[1][4] It was deposited in shallow marine environments along the western margin of the North American Craton during Late Cambrian time.

[4] The Lynx Group overlies the Arctomys Formation and the contact is gradational.
