Description: | The leaves of extinct tree ferns were attached to the stems of shrubs, scrambling creepers and trees that grew up to 10m tall. The plants are very distinctive because of the branching patterns and shapes of their leaves. They were an important part of forests in the Carboniferous period about 300 million years ago and usually grew on high river banks. They were the earliest seed bearing plants. Male pollen was shed into the air and carried by the wind to the large female seeds. | 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 |
