FOSSIL TROPICAL PLANT LEAVES

Annularia

300 million years old

Kilmersdon Colliery, Radstock, Somerset

 

Annularia is the name given to the leaves of Calamites, a giant tree closely related to living horsetails.  They grew to a height of up to 18 metres. They lived during the Carboniferous period and were a large part of the tropical Coal Measures forests.  

This beautiful fossil was collected in 1982 from the old tips of Kilmersdon Colliery when they were reworked for coal. Specimens as good as this are rare. It is presented in a museum display box with plastazote lining and a glass lid.

Radstock is a classic area for studying the plants that were living in Britain at this time. A diverse range of fossils were found on the coal tips up until closure of the last colliery in the 1970s, although further fossils did turn up when the tips were reworked for coal in the 1980s. ​​​​​​​

THE COAL MEASURES FORESTS

In the Carboniferous period Britain was situated near the equator and covered by dense tropical rain forest with giant trees and strange fern-like plants. Much of this vegetation became layers of coal, but some plants left impressions in mud which hardened into stone. 

Flowering plants had not yet evolved and the dominant vegetation was giant clubmosses, horsetails and seed ferns growing on the banks of the coal-forming swamps. Animal life at the time was dominated by insects which included dragonflies with a two-metre wingspan.
