Title |
Palaeolithic: Flint chopper / tool |
||
Description |
English: A possible Upper Palaeolithic flint chopper / tool, possibly dating to between 40, 000 BC and 10, 000 BC.
The find consists of a sub oval piece of a light brown flint nodule. It has been formed from either a flake of a large nodule or from the nodule itself. The flint tool has been damaged by movement in the soil due to plough roll and as such is badly abraded.
There is a small amount of evidence of direct percussion (conchoidal ripples) to the distal edge, to potentially form a serrated edge. However this could be the result of damage due to plough roll.
The flint tool measures 77.93mm in length, 53.53mm wide and 31.36mm thick. It weighs 79.2 grams.
Finds of Upper Palaeolithic date are rare, especially from Shropshire. |
