On a fossil tree found in an opencast coal site near Wigan, Lancashire

Authors


Abstract

The cast of a Coal Measures tree seen in position of growth is described. The cast is about 13 feet long, and evidence is given that the original tree trunk was probably at least 38 feet long before it became completely buried in sediment. The precise history of the tree is unknown but the rate of sedimentation round about it must have been very high.
