Can you fit a finger tip or your whole head inside the opening?

Not a projectile unless it came from the formerly unknown giant Puckle Gun (it had a 1" square bore).

I'd guess a bucket tooth from a backhoe.

Wow Charlie, you made me look up "Puckle gun". Thought you might be inventing "stuff".

Almost looks like a tooth from an excavator bucket? Tony

Tony... you may be right... in a way...
Now that you said that...
Dredge bucket.
