Description: | The original low-angled cone-shaped shell of this sea snail has a pattern of vertical ribs and spiral cords (rope-like pattern). The whorls (coils) of the shell increase in size towards the rounded opening in the shell where the snail could withdraw its soft body for protection. There is a groove in the shell known as a 'slit band' that formed a channel to carry water pumped out of the body away from the head region of the snail. | License: | http://www.imagine.org.uk/about/copyright/ | Rights holder: | Tyne & Wear Museums | Subjects: | fossils natural world | Source: | Tyne and Wear Imagine | Identifier: | http://www.imagine.org.uk/details/index.... | Go to resource |
