Rock.

[Brian C.]

Here is an interesting rock, may be an old bone. It came from a field that was an old fairgrounds. It could be just a rock, but some how it is kinda different.Any ideas.

It is interesting for sure but, I feel that you have a natural shaped rock. Keep looking and good luck!

Hard to tell from a picture, but looks like limestone. Limestone easily dissolves over the eons into unusual shapes. If you have some dilute Hydrochloric Acid (HCl) or muriatic acid, put a drop on the rock. If it fizzes, then it is limestone.
