As my first year at uni is now finished, I decided it was about time I id'ed some of the shark teeth in my 'unknown' box.....bad idea! give me molecular biology any time lol. Anyway, here are a few pics, I'd appreciate any opinions on them. In a few days I'll upload some more.
These four are all the same. Based on the reconstructed tooth set featured on Elasmo.com, i'm fairly certain these are upper anteriors of Hypotodus verticalis. Probably the first upper anterior judging by the relative width of the root. These are from the London Clay of Walton.
Based on the same tooth set as above, these are also H. verticalis. This time, lower anteriors. I was confused as it wasnt clear if the cutting edge extended all the way down the side of the tooth in all or some tooth positions. Elasmo shows that the anterior most lowers dont follow this, so im happy to agree with them. These are from the London Clay near Burnham.
This specimen i am a little less certain about, i think that it is an upper lateral from H. verticalis. This specimen is somewhat unusual in that it has two pairs of lateral cusps, although elasmo does note this. London Clay, Walton.
Thats all for now, but i shall put some more on soon.
thanks for looking
