Description: | These single fossil seeds are from an extinct tree fern and are all known as Trigonocarpus. The seeds were female and attached to leaves. They were large oval shaped structures and some grew more than 10cm long. The seeds were fertilised by male pollen that was shed into the air and carried by the wind. They were important plants in the Carboniferous coal forests and usually grew on raised river banks. | 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 |
