Description: | Calamites, often described as a giant horsetail, was a common plant in the Carboniferous Coal Measure forests 300 million years ago. The fossils of this plant are quite distinctive. They have fine, thin ridges that run along the length of the upright stems. These are crossed by joints that run across the stems. Flattened stems of Calamites are often found in shale. The modern horsetail plant (which is cursed as a weed by many gardeners) is almost exactly the same as this fossil, although much smaller. Calamites could grow up to 20m high. | 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 |
