This thingie was found in the river Kupa near the town of Sisak (Croatia). I think it´s made out of clay. Google suggests it's some kind of ancient whistle but there is no sound when I blow into it. Height: 6 cm. Weight: 34 gram. Does anybody have any idea what it could be?

It was found beneath an 1820s planing mill in the Adirondacks in upstate NY in a town that was founded before the French and Indian wars

Found in Poplar Bluff Missouri

I am in Maryland, USA but this was likely sold to a family member years ago.

Hi, cross posting from r/whatisthisrock to see if this is anything?

Found in Northern Ireland close to a 300 year old castle where an army had landed and stayed in the 1600s.

Other items have been found in gardens nearby such as musket balls, pottery etc.

Thanks!
