Description: | This snail is unusual because it has a fairly flat shell with a left-handed coil (most snails have a right-handed coil). It usually lived in fresh water and is often used to identify rocks that were deposited in fresh water. This specimen was found in rocks deposited in fresh and brackish (slightly salty) water lagoons, rivers and lakes that formed in flat low-lying land close to the coast when the climate was subtropical. | 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 |
