SE Texas - Trio

[johnnyvaldez7.jv]

Here's an unusual set. (A) has large holes so could it be a skull fragment to something? (B)  Turtle? (C) Antler?

These were found in SE Texas.

All bone for sure. A looks like softshell turtle or croc.

[Rockwood]

A Looks like an osteoderm. Croc would fit.

B I think bone may be the best ID

C Little doubt this is antler. Likely deer.

The very first piece looks like part of an alligator osteoderm to me, the thickness and the pitted surface are key identifiers. And I'm going to say that B and C are just unidentifiable chunks of bone. In my opinion C isn't an antler because while the insides of antlers are porous just like any bone, the actual pores themselves are much, much smaller than those in ordinary bone material, almost appearing solid. Also the second picture of C seems to show some sort of concave indentation that looks like it could be an articular surface, something you wouldn't see in between the tines of an antler, but it's so worn it's hard to tell.

The first piece is indeed croc/alligator.  But scutes (osteoderms) tend to be flat.  These cool beasts also have this texture on many parts of the skull and lower jaws, and those bones are more three dimensional as is this one.  This is a skull/jaw piece.  Possible a squamosal bone, but I would have to compare side by side to say for sure.

No, the texture of the interior of antlers is exactly like that seen here. The concave surface is not an original surface. The texture can be clearly seen in it.
