Ludwigia Posted March 25, 2021 Share Posted March 25, 2021 I visited my favorite shark tooth site today and came up with a couple of nice ones. But that's not the reason why I'm posting this time. This item here came out of exactly the same layer where I find most of my good shark teeth, but I have absolutely no idea what it is . It's from the Miocene Burdigalian exposure in the Lake of Constance area which I've been visiting for a few years, but I've never found anything like it here or anywhere else for that matter. I've not only found shark and ray teeth, bivalves and bryozoans here, but also the occasional rare land mammal tooth, so the layer was built right at the shoreline as far as I can tell, or at least in the tidal zone. I'm stumped! Any ideas? The object measures 4x2cm. A few pieces broke off which I managed to glue back into place, so I think that it's more or less complete. 2 Greetings from the Lake of Constance.

I've found a couple of teeth here. Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
FossilDAWG Posted March 25, 2021 Share Posted March 25, 2021 @Boesse would be the one to possibly give more detailed info. The size does suggest one of the smaller animals, but it could be an unfortunate juvenile of a bigger species I suppose. Don 2 Link to comment Share on other sites More sharing options...

Boesse Posted March 26, 2021 Share Posted March 26, 2021 Easy! This one is a tympanic bulla of a eurhinodelphinid, aka "swordfish" dolphins, like Xiphiacetus bossi from the Miocene of Calvert Cliffs. Rare find in Germany - lots of them from Belgium/Netherlands. 5 Link to comment Share on other sites More sharing options...

Thanks very much for your help. Looks like I've found something quite rare for these parts. 1 Greetings from the Lake of Constance.
