Now that is a nice find. It is part of a jaw with teeth in it. I do not know what type but it was a marine meat eater for sure.

The best days are spent collecting fossils

That is an extremely interesting fossil!

In the first pic, there are numerous tubercules on the "jaw bone", and in the second pic, the "teeth" seem to emerge at right angles to their "roots". I cannot reconcile these with anything I'm familiar with (which, admittedly, is little enough).

I am not sure that this belongs Lepidotes because your teeth are curved.
