Hi all,

3 fossils - hoping they are marine reptile vertebrae - any help with identification much appreciated!  Found today at Lavernock point, south wales.

First one I'm most excited about - I think it's possibly 2 (or more) vertebrae.  First picture as found in-situ.  The rock on the left hand side easily broke off the top of the fossil with hammer and chisel.

View on top of fossil once top had been broken off.

Fossil runs full depth of rock shown, and has a lip / protrusion at the bottom edge as well as top edge.

I tried to clean the fossil - next image shows underside of the fossil.  Can see shape of vertebrae I think and also one of the projecting parts just sticking out of rock on bottom of picture (not sure of technical name for this).

Next fossil I believe is very water worn and broken vertebrae plus a few other small bones.

Last fossil I'm not so sure - appears to have shape of vertebrae on front side (but no depression).  

Back side is unusual.  Structure looks like bone where surface broken, but could be wrong.

Front side below.

Rear side below picture - note small hole in middle of pentagon shaped part (looks like this pentagon shaped part is stuck on to the back?)

Side view - note the section is not constant thickness (crushed or broken, or perhaps just a funny shaped rock?)

Many thanks for help with identification!

H Matthew, I think the first specimen is Plesiosaur and the secon (+pssible 3rd) chthyosaur.

Would agree with that - nice little plesi vert and a couple of iccy verts. I like the natural cross section - classic hourglass shape!
The good thing about bones is they never run away

Hi Colin, Rockelf,

Many thanks for positive replies!

Would either of you happen to know anyone in the South Wales area who may be able to help me extract the plesi vert from the rock?

I feel like it could be a nice specimen if I could get it out and cleaned up without destroying it!

Thanks

Matthew

I think the first pics are of a cone in cone or infilled hole, there are quite a few at Lavernock. Agree with Ichy vert on 2nd lot of pics and last lot looks to be just a rock.

It's always great to "shoot" your own

Hi Steve,

Many thanks for your reply.

An infilled hole would be a worm hole or something like that?

Please could you explain more about the cone in cone?

I may try and break away some more of the rock - we think at the bottom of the fossil there is a projection of some sort (originally thought this was possibly part of spinous process).

Thanks again

Matthew
