Abstract: Analysis of sediment samples from Sun Hole Cave, Cheddar, has revealed the presence of the fossil land snail Retinella (Lyrodiscus) which is now extinct in Britain. Molluscs of the subgenus Lyrodiscus are presently restricted to the Canary Islands but were widespread in Europe in the late Pliocene and early Pleistocene.
