The Conception Group is a geologic group in Newfoundland and Labrador. It preserves fossils dating back to the Ediacaran period. It mainly contains turbidites, but is interrupted by a glacial diamictite, and tops out with sand and siltstones (these dated to 565 Ma).^[1] It corresponds to the lower portion of the Connecting Point Group ^[3]

In some areas the Drook formation continues from the base of the group to the base of the mistaken point fm; elsewhere (in cantral / south Avalon) the Briscam, Gaskiers & Mall Bay Fms wedge in. ^[3]
