Rhizodont (Rhizodopsis) teeth in the Coal Measures

After finding a Rhizodopsis fish scale at a locality in a nearby ghyll (see that blog here); Tom returned to look for more fish remains. On finding a single tooth, Tom brought the small slab back to reduce it in size and clean it. On splitting the shale a further 3 teeth were revealed.
