Description: | The skeletons of starfish are made up of many plates of calcium carbonate. Normally, after death, these skeletons disintegrate and only fragments remain to become fossils. The Silurian rocks at Leintwardine are famous for well-preserved fossil starfish. It is thought that in late Silurian times, Leintwardine was located at the margin between the shallow and deeper part of the sea. There is evidence that submarine landslides (turbidity currents), flowing from the shallow to the deeper part of the sea, buried these starfish alive, ensuring that their complete skeletons would survive as fossils. | 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 |
