It is a very worn ammonite, but without knowng the area it's from (and hence the geology)  I cannot say more.

Hi 
As Colin says, could you say where you live. 
I suspect this maybe a Tulites ammonite found in the Fuller's Earth - perhaps Dorset / Somerset / Gloucestershire

Looks like our posts came through at the same time. 
Peterborough seems to have a complicated geology but it includes the Blisworth Limestone which is equivalent to Fullers Earth Rock.
So Tulites remains a possibility

Cadoceras from the L. Callovian Kellaways Formation?

Thank you, it’s a little odd too If we hold a torch up close to it sort of illuminates. The light passes into the fossil?

That's probably due to the translucence of the crystalline calcite that makes up the ammonite
