Triassic Ichthyosaur paddle bone I.D?
I visted Aust Cliff on the River Severn, Gloucestershire UK back in Feburary and managed to find a large block of the 'Rhaetic Bone Bed' . Lots of bone fragments, fish teeth, even a shark fin spine! But my best finds are a paddle bone and large tooth. (Still got plenty more rock pieces to break open and search for more, so a long term project...)
However i would like to I.D this Ichthyosaur in particular. Does anyone know about the early ichthyosaurs from the late Triassic?
To answer my own question, I've been scouring around on Google and TFF a bit and found plenty of low-quality photographs, which kind of convince me that, indeed, this tooth belongs to Severnichthys accuminatus. Though it lacks the striations at the base of the crown,not all teeth seem to have them going equally high up - and my specimen is far from smooth in that area anyway (kind of what you might expect from "rolled" ridges). Size, thickness, curvature and carinae all match. Plus, these teeth
