Calliostoma nodulosum


    • Specimen of a fossil gastropod, Calliostoma nodulosum, collected from the Barton Group, Barton Clay Formation of Tertiary, Middle Eocene, Lutetian - Bartonian age from Barton, Bournemouth, Hampshire (SE England). Collected by William K. Loftus. The shell of this cone-shaped sea snail has spiral ribs covered with rounded knobs. Calliostoma lived attached to seaweed and probably fed on tiny food particles that it filtered out of the water. It was part of a community of animals living in a shallow subtropical sea. The shell was one of the first British fossils to be given a scientific name using the new Linnean classification system by Daniel Solander in 1766. The specimen was found in Hampshire. It is from the Tertiary period (65 - 1.8 million years ago)
