Ludwigia Posted October 4, 2020 Share Posted October 4, 2020 I visited the Kimmeridgian ditch again this week and just finished prepping the finds. I didn't do too badly this time, I'd say. Parataxioceras sp. & Ataxioceras hypselocylum on matrix. 16x12cm. Involuticeras involuta with a Pseudolimea sp. bivalve ø7cm. Laevaptychus obliquus with a small Glochiceras sp., an even smaller and pyritized Aspidoceras sp. and a sponge. 7x7cm. Two more Laevaptychus obliquus, parts of the jaw from Aspidoceras ammonites. Both are 5cm. long. Taramelliceras compsum. ø7cm. Aspidoceras sp. phragmocone with part of the living chamber. ø14cm. 17 Greetings from the Lake of Constance.

There's still a certain amount of uncertainty about the actual purpose of these things. They actually come in pairs and are either jaw parts or else a 2-part hood which closes the aperture. You can see the latter on modern Nautilae. Aptychi have different shapes, depending on the species they are associated with. They've been found from the Devonian through to the Cretaceous Periods, but only very rarely directly within the aperture of Ammonoidea, which is why it's not always possible to say with absolute certainty which species they belong to. 1 Greetings from the Lake of Constance.
