Tree bark fossil. This pattern,preserved in rock dating to the Lower Carboniferous Period (360-286 million years ago),is from the bark of the trunk of a Lepidodendron sp. tree. These plants grew in swamps. The remains of the plants from this time form much of the coal reserves in the ground. This diamond-shaped pattern was typical of the bark on the upper part of the tree. These enormous trees grew to 30-40 metres in height. The only surviving relatives today are tiny mosses. The area seen is 11 centimetres wide | |
