fifbrindacier Posted April 10, 2017 Share Posted April 10, 2017 Hello, in the Kimmeridgian of la Pointe du Chay i also found this item. I thought it could be a kind of spondylus withut any clue for the species. It is 2 cm long, 1 cm wide and the "back" of the valve is 0,5 cm high.

Fossil-Hound Posted April 11, 2017 Share Posted April 11, 2017 Appears to be a single mollusk but I'm not sure what type. Perhaps a new species! Spondylus was a bivalve (two shells) and this appears to be singular (half shell). Not sure though as I'm unfamiliar with the geological and setting of your location. Read some books and consult with some other fellow collectors. That's part of the fun with this hobby. We get to play detective. Do or do not. There is no try. - Yoda Link to comment Share on other sites More sharing options...

Ludwigia Posted April 11, 2017 Share Posted April 11, 2017 All I can say is I'm stumped, since it doesn't appear to resemble any spondylus or trigonia that I'm familiar with. Can you make sharper closeups of the shell structure? @jsnrice Bivalves become unhinged, so it's not at all uncommon to find half shells. 1 Greetings from the Lake of Constance.

Fossil-Hound Posted April 11, 2017 Share Posted April 11, 2017 @Ludwigia most of the bivalves I've found come in neat pairs of two, but you do have a point. I'm not familiar with the geology of that area and perhaps over time the weather and rock shifting removed the pieces. I wonder if he could disconnect the shell from the matrix. That might ruin the fossil though. Do or do not. There is no try. - Yoda Link to comment Share on other sites More sharing options...
westcoast Posted April 11, 2017 Share Posted April 11, 2017 I'm having a hard time seeing this as a bivalve, but I don't have any useful alternative suggestions. Link to comment Share on other sites More sharing options...

fifbrindacier Posted April 11, 2017 Author Share Posted April 11, 2017 Thanks to all of you to take a look at it. I had the idea it could be a spondylus because of its general shape and the aligned decorations, but without finding a real match. I hope i didn't mislead you with that idea. I'm sure this is nor a trigonia nor a brachiopod, but i might be wrong. And i don't know if it has chances to be an anomia or no. Here are other pics. Some are a little blurry, not too much i hope.

Ludwigia Posted April 11, 2017 Share Posted April 11, 2017 That bumpity-like sculpture is confusing. Part of a gastropod? Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
fifbrindacier Posted April 11, 2017 Author Share Posted April 11, 2017 Those little decorations look like the ones you can find on a porifera, but it has the aspect of a shell. A bit of gastropod is a trail i'm going to follow. I had the idea of spondylus because when i looked on paleontological sites about that area i found something that looked like that, but without a complete match and with different periods on that site :http://paleo17.blogspot.fr/search?q=spondylus.

abyssunder Posted April 11, 2017 Share Posted April 11, 2017 With the new pictures I could say that is not Spondylus, it's a gastropod, no doubt. It would be close to Conidae, like Conus, but the temporal range is wrong for that, also the ornaments.

fifbrindacier Posted April 12, 2017 Author Share Posted April 12, 2017 Is a club shaped the base of the urchin spine ? If so, it must have been a big one and would explain the ornamentation and the unsual shape. I found other urchins spines at a few meters : Balanocidaris marginata, Paracidaris florigemma and Pseudocidaris mammosa. "On ne voit bien que par le coeur, l'essentiel est invisible pour les yeux."

fifbrindacier Posted April 12, 2017 Author Share Posted April 12, 2017 I'll try to desengage it a little without damaging it to see if there is something worth to its ID.

fifbrindacier Posted April 12, 2017 Author Share Posted April 12, 2017 No, it's not a crinoid, i don't think so. It is fixed on a little lopha, i found it among lophae, ceratomyae, mytilidae, terebratulae, corals, cidaris urchins and near there was what seem to be thalassinoides burrows (but i didn't take photos) "On ne voit bien que par le coeur, l'essentiel est invisible pour les yeux."
