Nice jaw section, well the plesi verts are down there, I was lucky enough to find two joined last summer, they came from a recent fall but I could not find anymore of it.  Will pop some photos on when i can then after prep as well.

Where are you Ichthyosaur.

This little bit of jaw has stumped us. It can't be ichthyosaur, as ichthyosaur teeth fit into grooves, not sockets. We considered shark fin spine but in cross-section it is the wrong shape and the spines we have do not have sockets for the 'teeth'. So, what can it be? Plesiosaur? Fish? Or (dare I say it) pterosaur? Measurements are: 2 centimetres in width, and 1.5 centimetres in height. 3mm in cross-section.

Second pic, showing the sockets quite nicely:

Third pic, with the last tooth:

Thanks in advance!

Thanks, VF

Could we see photos of the cross-section ? (both ends if possible)

Hi

It looks like a small piece of plesiosaur jaw from about half way along the bottom jaw.

Nice find.

Regards

Plesi bones are rare down Charmouth and Lyme Regis. Plesiosaur skulls are even rarer due to how fragile they are. Finding a bit of Plesi jaw is an awesome find, even if it is a small bit. Good find, well done!

Thank you, Fossil Hunter and Koss. It was a bit of a 'bonus' find to be honest; I found it thinking it was a scrap of ichthyosaur jaw. When I put it to the toothbrush when we got home however, I was very surprised to see the tooth sockets - and, indeed the tooth emerge from the mud covering the top. This is just the fourth bit of plesiosaur material in my collection. I can't wait to find that complete plesi vert just lying on the beach. Maybe one day.
Thanks, VF

Articulated plesi verts? Man, that's cool. Definitely want to see pictures. I've got a few rolled plesi verts and scraps of Plesi bone but nothing articulated.

If the articulated verts are from Monmouth beach chances are they are part of this

Lovely! My first ever vert was from a plesiosaur - walked onto Charmouth beach in mid-summer, literally scores of fossil hunters scouring the tide line, and picked it up after about two minutes on the beach. You never know when you'll get lucky - although I've never yet found a bit of jaw - great find!
