Notidanodon Posted June 21, 2022 Share Posted June 21, 2022 Hi guys, not too sure how reliable the provenance on this is but it’s supposedly from cadzand, Netherlands, I got it in a lot of dolphin tooth, but the serration reminded me of squalodon which it obviously isnt but I was wondering if anyone else had any ideas 1 Link to comment Share on other sites More sharing options...
ziggycardon Posted June 21, 2022 Share Posted June 21, 2022 Could perhaps be Delphinodon dividum or Eurhinodelphinidae. I am not an expert on prehistoric dolphin unfortunately, but I now both are present in Cadzand.

pachy-pleuro-whatnot-odon Posted June 21, 2022 Share Posted June 21, 2022 (edited) All I know of Cadzand is the Miocene (if I'm not mistaken) age, and the shark and ray teeth and shark vertebra I used to find there as a kid. Maybe @Shellseeker can help figure out what kind of cetacean this could be? And perhaps @sjaak knows whether this type of preservation matches Cadzand? Although I do think it also wouldn't be a bad match for Kaloot (never searched there myself, though, and have only seen little material from there).

The book is in Dutch but based on what I've seen before from there and what I understand of Dutch (haven't studied it but it's similar to English and German), you get fossils of a range of ages from there (maybe as old as Eocene and certainly some from the Pleistocene). That looks like a more modern dolphin (Pliocene-Pleistocene) but I've seen some small teeth from as far back as the Late Oligocene that look rather modern.

Hi Jess, If you've got any information in that book that might be pertinently to the ID and are able to scan it, we've got a couple of Dutch forum members - myself included - who probably wouldn't mind translating or summarising sections You're right, though, in that, as far as I'm aware, the dredged sands deposited on the beach there cover multiple ages... You can even find palaeolithic flint tools there, as I've done myself '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...

I think the publisher is Nederlandse Geologische Vereniging Afdeling Amsterdam. It has some photos and line drawings but nothing close to that tooth. I don't think I've seen a tooth like that from the Sharktooth Hill Bonebed. I don't think I have a tooth like that from other Miocene sites nor from the Pliocene. I'll take a look.

Shellseeker Posted June 22, 2022 Share Posted June 22, 2022 I do not have an answer, but I did find a dolphin/whale tooth tip, with a similar collar on the tip 1 1 The White Queen ".... in her youth she could believe "six impossible things before breakfast" Link to comment Share on other sites More sharing options...

sjaak Posted June 23, 2022 Share Posted June 23, 2022 Strange tooth for Cadzand. Maybe you could contact Hidde Bakker or Klaas Post on social media or contact this museum: https://www.hetnatuurhistorisch.nl/contact/ 2 Link to comment Share on other sites More sharing options...
Boesse Posted June 25, 2022 Share Posted June 25, 2022 Hi all, the tooth in question has an extra little cusp on it and a bit of cingulum - and does not resemble any post-middle Miocene dolphins. These sorts of teeth - single rooted, with crowns that have any ornamentation on them - are generally characteristic of lower to middle Miocene dolphins. This one compares relatively well with the early Miocene dolphin Araeodelphis natator from the Calvert Formation: 2 1 Link to comment Share on other sites More sharing options...
