  • Wondering what this is...

    Found this 4" fossil in a stream bed in Round Rock, TX. Most of the fossils around here are marine, but occasionally find petrified wood and a coprolite, also dino footprints. I thought it might be bone but not sure because the ends are odd, one is a little rounded off and the edges of the hollow almost looks worn rather than broken. Any thoughts on what it might be?

    Yeah I could see where you would think its a bone. I'm not 100% either. We have some great fossil folks here. One of them will come along and nail it down. Definitely would have come home with me also.
    The chase is better than the catch...

      Its a fractured/broken piece of bone. I can't tell if it's a fossil from the pic. A fossilized bone would be heavier, and of course harder. Could be a worn down awl or gouge if it was anything. But coming from a creek bed it could also just be a broken bone. That one is a little iffy. Thanks for posting.

        You’ve presented a tough one ! Something for scale ?

          Definitely fossil. I've found what I'd call semi-fossilized bone around here, bison and cattle, but this one is solid rock. Thinking it might be a small horn coral, but it's just different than the other coral fossils I' ve found. My kid thinks its a plesiosaur tooth. I doubt it, but can't say what it is. Both ends are odd. One is rounded off like its been worn, the other doesn't look like a joint.

            Tis bone sir, not fully permineralized. (Most definitely not tooth anything)
            I have some deer horn in this condition. When struck on hard item it has a certain "ting"
            As for origin, a pinpoint ID would only be speculation.
