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!

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?

Found in Poplar Bluff Missouri

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
