Description: | Stigmaria is the name used to describe the roots of large tree-like club mosses that grew in Carboniferous coal measure swamps 300 million years ago. The upper parts of these plants, which could reach heights of 30 metres, are known as Lepidodendron. Stigmaria is easily recognised by the regular pattern of small circular pits (showing the position of rootlet like rhizoids) that cover the surface of these fossils. | 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 |
