Fossil or rock?

[J Wales]

My niece recently found this on top of the ground at the base of an oak tree at our hunting spot in south Taylor County (south of Abilene). I sure could imagine it to be a fossil from a wooly mammoth or something along those lines. One end of it is porous, like a bone fragment would be. Could this be a fossil? Or just a cool rock?

Just a cool rock..

I think it’s bone, that porous end looks like the shaft portion of a bone and porous texture certainly makes me think it is fossilized

[J Wales]

Thanks for the opinions so far. Any more thoughts?

My guess is a cool rock... I believe what you're seeing to be a porous end is just weathering that has eroded a particular mineral in the rock. In the picture it appears to have a pink tint to it, probably meaning it has quite a bit of K-feldspar or maybe oxidation, and also looks like a very fine grained possibly siltstone... just my guess though

Another vote for rock

Agree with KnightTime

Given where it was found, just sitting on the ground, I'd say it's a rock. Compare it to rocks in the area. A fossil will be different than the rock formation in which it was found.

Lick it! lol the porosity of fossilized bone will typically cause your tongue to "stick".

Looks like a sex stone to me
