I really like the sturdiness of the Bothriodon sp tooth when held in the hand from the Isle of Wight, Lower Hamstead Beds in Bouldnor , and I would really like to know are these indents possible wear facets (indicated by the blue arrow). But before I can really ask that question with confidence, I thought it would be best to ask which end of the tooth is the root and which end of the tooth the tip is. @TXV24
