On Dinocochlea ingens, n.gen.et sp., a gigantic Gastropod from the Wealden Beds near Hastings

Abstract

During the construction by the Hastings Corporation of a new arterial road to th.e north of St. Leonards, near Silver Hill, not far from the Old Eoar Waterfall, and close to the quarry dubbed by Mantell the “Iguanodon Necropolis”, the cutting passed through some sandy beds of the Wadhurst Clay Series. In these there was one particular stratum that had been a pale blue concretionary calciferous sandstone, but which had been altered for the most part by the percolation of water into a rusty-brown ferruginous sandrock.1 Numerous large, typical concretions occurred in it, but besides these Mr. H. L. Tucker, who was then acting as engineer to the contractors for the work, noticed the presence of certain huge spiral bodies that seemed to differ from the ordinary concretions. These bodies generally lay in cavities, or “moulds” in the surrounding sandstone, but unfortunately no part of these moulds was preserved.
