Description: | Cyclopteris is the name given to individual leaves of the seed fern Neuropteris when they are found on their own. The seed ferns flourished in the Carboniferous period about 300 million years ago and were spread around the world in the Jurassic period and became extinct at the end of the Cretaceous period about 70 million years ago. They were small shrubs that had seeds and pollen producing organs on their leaves. This fossil shows fan-shaped leaves with digitate (finger-like) leaflets, from which the species name is derived. | 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 |
