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. Like most fossil seeds it was found separated from the parent plant, so the type of pteridosperm is unknown. The seed has kept its shape but none of the original organic material remains. | 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 |
