Description: | These large fossil leaves known as fronds are made up of smaller irregularly shaped leaflets. Seed ferns formed either shrubs, scrambling creepers and trees that grew up to 10m tall. Seed Ferns were the first plants to have seeds for reproduction. They were most common in the Carboniferous period but became extinct in the Cretaceous period. They were an important plant in the Carboniferous coal forests and usually grew on raised banks alongside river channels. | 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 |
