Chronology: Broad Period: New Stone Age - Neolithic:

Specific Circa: 4800 - 2500 BC – Doggerland Salt – Marsh:

Dimensions and weight:

Diametre [upon the oval]. 91 mm x 104 mm:

Height: 71 mm:

Weight: 762 grams:

Description:

This is likely a fossilised Echinocorys, a type echinoid [sea urchin] which, has a naturally occurring oval doomed spherical form: The creature existed in the Cretaceous period 144 – 66 million years ago: It has however, been modified by modern-humans in the prehistoric Neolithic era: It is unclear to me if this tool was hand held or hafted, the underside recessed cylindrical cavity, appears to show flint modification via percussion knapping and cortex modification: It may have been hafted upon a wooden branch junction or Red Deer antler: Unfortunately we may never known beyond ‘experimental archaeology’:

All of the outer surfaces are highly polished and the front striking doom clearly shows impact and grinding wear evidence of impact striking with external erosion of the outer cortex:

Provenance: Original Finder

Recovered upon the Fen edge in Northern Cambridgeshire along a length of ancient dry riverbed: This area of land would once have been a salt- marsh with possible tidal flooding from time to time at the time when this tool was in use: Interestingly I have recovered a number of tools in the general area suggesting possible semi-permanent seasonal occupation:
