Hammerstone or battered lump?

[Pedrosky]

I saw this lump of flint a while back and kept it as it stood out so much. I thought it might be a hammerstone because there are so many knocks and dents in it and can’t imagine this could have been caused by the plough. I’m hoping someone on here might know. Thanks for looking

That's ancient frost spalling, it's very distinctive. Probably happened during one of the glacial periods.

Hammerstones tend to have all the bashing and chipping concentrated at one end or on one face.

Thanks Fred. After a little research I didn’t think it was a hammerstone after all but didn’t know about the frost spalling. I’ve learnt something new, cheers.
