Please help me to identify this piece

[stphaniesuer]

I live in Austin Texas. My husband found this buried approx. 5" below the dirt. Can anyone tell me what it is. You can hold it in your hand and your fingers fit perfectly. It has one side that is a bit more concave that the other and there are three spikes at the top, curved at the bottom. He also found a flat stone approx 4" round. He lost that stone.
Please let me know. I wanted to take it to U.T. but I was told that the next identification appt would not be until mid August. I have to say this is the largest and most interesting piece I have ever found.
It is a limestone (chalk) stone. It is not bone.

No comments or pics of the "edge"?

Please help identify , found on my land near old creek bed outside of gatesville, Tx
I’m guessing maybe hand axe but not certain even of time period, have hundreds of flint tools I’ve found but not very experienced thanks measures about 3” long but round hammer blunt on one end ?

I'm not seeing anything man made.
