Not sure about these. One is tooth I am sure.

This large one I had in my garden. My friend said it looked like a big bone. Could it be? The small one I found while hunting for indian relics and am pretty sure is a tooth. Tell me what you think.

I think the larger object is a concretion of some sort -- not a fossil.
The smaller object seems to have a pattern in its surface. It may be a cast of a solitary coral, but I'm not certain.

Not sure what concretion is. But, it is definately some kind of stone.
