Actual pseudo nothing?

[sharko69]

Found this yesterday while out with Dallas Paleo group. Looks like it has to be something. It is very worn but the shape suggests tooth, claw, or rostral. Everyone was stumped. Could be great pseudo fossil but looks too perfectly shaped. Any thought?

Did you get this at Post Oak Creek in Sherman Texas yesterday. It is late Cretaceous, but lots of stuff drains into that creek. Whatever it is has been well tumbled by the water and looks like a suggestively shaped rock to me. But maybe someone else will weigh in.

Looks rocky to me too, can't see any bone texture and it's certainly not a tooth.

It was at Post Oak. It is so perfectly shaped and semetriical. I am sure you are probably right but it is the best looking fauxill I have found if that is the case.

Just a thought and I am sure I am way off, any chance it is horn core from a small horn?

I have found coral there, but horn corals, Rugosa, died out in the Permian with the great extinction. Post Oak is Cretaceous or younger.

A wild guess : a kind of sponge ?

Maybe an ironstone concretion similar to the one from this topic.

There are Cretaceous horn corals but this is not coral for sure. Thank you.

Not iron I am sure. Though many do exist and have fooled me for fossils in the past. Thank you.

I have to go with an oddly shaped rock, just looks wrong for a fossil.

When i did some research on the Horn Corals (Rugosa), everything i read said they died out in the Permian. Where can i find info on them being in the cretaceous? Not disputing it, just curious.

There were some corals that somewhat resemble the rugose variety, such as solitary scleractinian corals.

I think you were asking if this might be the core of a horn, but a lot of people are assuming you meant horn coral. For what it's worth, I doubt it's either - I'm tentatively in the ironstone concretion camp.

I think you are right on all counts.

Good to know. Thought these were horn corals or at least that was what I was told. Now I know better.
