The Redmond Formation is a geologic formation in Newfoundland and Labrador. It preserves fossils dating back to the mid-Cretaceous (Cenomanian). It was a thin (up to thick) and restricted unit traced for in a single mine (Redmond No. 1) in Labrador, overlying Paleoproterozoic rocks, with large amounts of rubble, probably as a result of graben subsidence within the Labrador Trough. Argillite facies within the formation have produced a diverse flora and insect assemblage.Demers Potvin & Larsson, 2019
