Unknown Jaw From Sulphur River

Found in the north sulphur but was thinking mammal which would take us to Pleistocene. What does this belong to? I assumed tusks due to the length and direction.

The bone looks like fossil fish bone to me. Is there any way it's Xiphactinus?

Fish seems likely, given the 'flakey' bone texture. Reptile is a possibility too.

Could be a Protosphyraena partial jaw section because of the oval like tooth sockets, fish for sure---Tom

Xiphactinus

Looks like a worn premaxilla from a LARGE Xiphactinus. Nice!

The teeth are over 1/2 inch wide. Any guess as to the possible size? I never gave fish a chance because it seemed too large. There are two teeth and a smooth spot where a third one would be. Found three xiphactinus pieces in the same area, so maybe another trip is warranted there. Everything I find is river wash, but we will find more places in the near future. Our collection is growing with a few cool pieces. Thanks again to all that help me learn and I hope to help id things once I have more time under my belt.

Xiphactinus

That would be an X-fish in the 15-17' range.

We have had good luck as of late finding interesting things. All of this comes from gravel bars that most don't have the patience for. I long to find something where it has been laying for quite some time.
