Description: | This large Gryphaea shell is a very good example of a 'Devil's toenail', as these fossils are sometimes called. Gryphaea is a relative of the modern oyster, and is also related to clams and mussels. The difference though, is that the two shells of the Gryphaea have very different shapes. The thinner outer shell is large and curved with a very rough, flaky surface, like a neglected toenail. The smaller, flat shell is very thick. | 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 |
