Hi All,

Brought some bone bed back from a recent trip to Aust. Got a number of nice sized severnichthys teeth from the bone bed (will post some pics of those in the near future), but also these two verts. The larger of the two is partial, maybe two thirds. Are they small Plesi verts?

The partial one is plesiosaur but the other one is an ichthyosaur vertebrae.

Thanks Pete. How can you tell the small complete one is ichthyosaur?

Cheers

Hi Rosco,

I think the general rule of thumb is the overall shape. Hockey puck = Ichthyosaur, Cotton reel = plesiosaur.

The smaller vert also looks to be plesiosaur, as photo 15 clearly shows two paired foramina on what i presume is the ventral surface. This is a classic diagnostic feature of plesiosaurian vertebrae.

They do appear to be foramina, I'll load up another couple of pics in the morning

Here are some more pics. The first is of the dorsal surface I think, then the rest of the pics rotating over to the ventral side with the two foramina I think -
