Description: | This irregularly shaped leaflet was part of a larger leaf known as a frond. Seed ferns formed either shrubs, scrambling creepers or trees that grew up to 10m tall. Seed Ferns were the first plants to have seeds for reproduction but became extinct in the Cretaceous. They were an important plant in the Carboniferous coal forests and usually grew on raised banks along river channels or deltas. | 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 |
