Plaster-cast of dinosaur footprints, discovered in the parish of Newton Nottage in 1878, by Mr. T. H. Thomas. These footprints resemble those of a Brontozoum described by Htichcock and Deane in Abbottsville, Massachusetts, and Smith's Ferry, Connecticut. This species is named 'Brontozoum Thomasi' after its finder, but seems identical to the American species B.Validum. This is the only stone on which the impressions of the bird-footed reptiles of the Triassic Age that has been discovered on this side of the Atlantic Ocean. The stone slab on which the footprints were discovered was presented by its owner, Colonel Picton Turbervill, to the National Museum of Wales, Cardiff.
