Occurrence of the Musgravetown Group in southeastern Newfoundland | ||||
The Musgravetown Group is a terminal Ediacaran stratigraphic group of terrestrialish sandstones, lavas and tuffs[4] cropping out in Newfoundland.
It corresponds temporally to the Signal Hill Group further east.
Mills and Sandeman (2021) proposed elevating the Musgravetown Group to supergroup rank, subdivided into the Crown Hill Group, Rocky Harbour Group and Bull Arm Group.[6]
