Description: | This pointed oval-shaped fossil is a seed. It is from the earliest group of seed plants, the pteridosperms that were common in the Jurassic period (about 170 million years ago) but became extinct in the late Cretaceous period about 70 million years ago. Unusually the seed was found in rocks that were laid down in a sea. It must have been carried to the sea by a river. | 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 |
