onafets Posted December 9, 2023 Share Posted December 9, 2023 Hi everyone. I received this ichthyosaur tooth from holzmaden, probably ohmden quarry, but I can't identify the genus. in the holzmaden area there are many species of Ichthyosaur. Maybe the most common is Stenopterygius. Can anyone help me identify this tooth please? Size approximately 1,5 cm Link to comment Share on other sites More sharing options...

RuMert Posted December 9, 2023 Share Posted December 9, 2023 Isn't it too slender for ichthyosaur? @pachy-pleuro-whatnot-odon Alexander, what do you think? 1 My sites & reports Link to comment Share on other sites More sharing options...
onafets Posted December 9, 2023 Author Share Posted December 9, 2023 do you think it's a reptile tooth anyway? @RuMert Link to comment Share on other sites More sharing options...

pachy-pleuro-whatnot-odon Posted December 9, 2023 Share Posted December 9, 2023 This is an Eurhinosaurus longirostris ichthyosaur tooth. Usually, such teeth exhibit horizontal banding, though this feature doesn't need to be present. It also appears that just the neck of the tooth has been preserved and not the actual root, which would've exhibited folding in the way typical of ichthyosaurs. Eurhinosaurus-teeth can be very tall and slender. Yet what gives it away in this instance is the constriction towards the tip of the tooth. Compare with the specimen below from the Steinkern-community. You can read up on these teeth a bit more here: 1 'There's nothing like millions of years of really frustrating trial and error to give a species moral fibre and, in some cases, backbone' -- Terry Pratchett Link to comment Share on other sites More sharing options...
