The gastropod to the left has been collected in the so-called "nose-chalk". The genus Tatara was until now known from the Eocene and Miocene of Australia only. The Danish species suggests a connection between the North Sea Basin and the Australian region. It has been established and described as Tatara danica Schnetler & Petit, 2006.

The photo to the right shows a silicone rubber cast of an impression in corallian chalk. On the photo of the adult specimen (estimated height 25 mm) knobs on the columella and the internal side of the labrum can be clearly seen.
