Turritella Edita gastropod mollusc collected from the Eocene Barton Beds of Barton, Hampshire. Turritella is a genus of marine gastropod mollusc which is still around today today. These specimens are in good condition; they have smooth shells which exhibit fine striations and the textbook turreted or 'unicorn horn' shape. The shells measure between 20 and 300 mm from the base of the aperture to the apex of the shell. Each specimen is supplied in a small plastic bag and would make a welcome addition to any collection.
