SE Texas - small bone?

[johnnyvaldez7.jv]

Was a good day today out hunting. River is receding leaving small gifts. Also saw the fattest and biggest water moccasin I'd ever seen on the gravel bank which was a bummer. After chasing him off I found this cool little point which is my 1st out here.  But I also found this little bone that is either highly eroded and gave it this shape or it is that way. I can tell that the cracks are filled and the matrix along the bottom is gonna have to stay for a bit cause I'll end up breaking it if I scrape it with dental picks.  It is brittle and appears old as other similar bones I've found here. But it was just unusual and thought I'd see if anyone might be able to tell if it's eroded into that shape or the bone is in fact not far from its original. It's 3/4 inches wide and 1.75 in length.  Sorry for the hand held pics just wanted it closer.  Found on a gravel bank here in SE Texas.
