Description: | Pieces of flint come in all sorts of strange shapes. Sometimes, they are long and thin, and can look like bones or teeth. They are often mistaken for parts of skeletons. Flint fossils are quite common, but not in the north east of England, as the rocks here are older than the Chalk in which flint is found. Common flint fossils include sea urchins and sponges. Sometimes these flit nodules can be found on the beaches in the North East. This is because they were brought here in ships which used rocks from the South as ballast (in order to keep the ship sitting correctly in the water). These rocks were then later dumped when the ship took on its true cargo (usually coal). | License: | http://www.imagine.org.uk/about/copyright/ | Rights holder: | Tyne & Wear Museums | Subjects: | rocks and minerals natural world | Source: | Tyne and Wear Imagine | Identifier: | http://www.imagine.org.uk/details/index.... | Go to resource |
