Designations: GCR (No: 468), SSSI
The quarry face and floor are dominated by a rich fauna. The best example in South Devon of fossilised corals in their position of growth and the best section in South Devon of the upper part of the Daddyhole Limestone Formation (Late Eifelian)GCR block / key theme: Marine Devonian
GCR Statement of Interest: "Dyer's Quarry exposes the best sections available of the Upper horizons of the Daddyhole Limestone (late Eifelian); horizons which are not exposed at the type section, Daddyhole. There is a rich fauna dominated by corals which can be observed in the quarry face and also on bedding planes on the quarry floor. This locality is of particular interest in showing the presence of corals in their position of growth, the best example in south Devon, and lateral changes in coral growth and species distribution related to the substrate."
