The Redmond Formation is a geologic formation in Newfoundland and Labrador. It preserves fossils dating back to the Cretaceous period. It was a thin (up to 1.5 metre thick) and restricted unit traced for 152 metres in a single mine 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.[1]
