Hi all, I bought this Kimmeridgian plesiosaur tooth from the Faringdon sponge gravels a while back. It came identified as Colymbosaurus sp.. At that point, I simply accepted this identification, seeing as the teeth of Colymbosaurus (or, at least, what's suspected of being Colymbosaurus) were already known from the Etches Collection and I didn't really have the means to verify the ascription from online sources. Today, however, The Etches Collection posted a video on Kimmeridgian plesiosaurs on their YouTube-channel, which make it abundantly clear that my specimen doesn't correspond to Colymbosaurus (video referenced below, as is a photographic excerpt of the teeth). The teeth of Colymbosaurus are not only subtrihedral but gracile in shape, they also have very strong striations - much stronger than in my specimen and almost pliosaur-like. The striations on my specimen, on the other hand, are way more similar to those of the Oxford Clay Tricleidus seeleyi, with very fine striations all along the tooth, a round cross-sections and (obviously) without carinae (just to rule out marine crocodile). My question now is: can my tooth be identified as to species or even genus? Could it be that the temporal range of Tricleidus extended into the Kimmeridgian? Might this tooth belong to Kimmerosaurus? Steve mentions in his video that there are more plesiosaurs that remain to be described from the Kimmeridge Clay, so, with that in mind, should I just classify mine as "cf. Crypticlididae indet."? Any ideas and suggestions welcome, but will just also tag @paulgdls and @DE&i.
