Welcome to TNET!
It's not a tooth. Your last photo shows the interoir veining, which is quite extenive and would not be present with a large tooth. Your item looks very much like a section of a rib or an arm bone.
Nice save!
Again. There is no enamel, nor is there a sign there ever was enamel. It's just a random chuck o' bone.
well just my luck thanks all .do you think it worth something??
