doushantuo Posted June 2, 2018 Share Posted June 2, 2018 looks like someone may have been part of the Marine Mollusk Workshop Nice detailed ,sharp & large pix,from someone whom I'm guessing knows his bivalve systematics(because of the posting of all these hinge lines) Ricardo probably knows this fragment from a bit of classic "hinge" lit 2 Link to comment Share on other sites More sharing options...

Max, Before sculpture you must look first to hinge, ligament, pallial sinus/line, adductor scars… See some of the hinge pictures to help you please.

doushantuo Posted June 2, 2018 Share Posted June 2, 2018 Max:distribution chart of Eemian mollusca in the Amersfoort borehole source: Max,concerning the ecology and/or distribution of mollusca in temperate waters: I have the feeling(could be wrong,though) that Arntz,Brunswig & Sarnthein(1976) could be informative,but I'm basing that solely on author reputation and publication reputation.plus:your German would have to be up to scratch. I don't have that paper,and it looks like it is hard to get . 2 Link to comment Share on other sites More sharing options...
Max-fossils Posted June 2, 2018 Author Share Posted June 2, 2018 About #8 On 6/1/2018 at 7:05 PM, Max-fossils said: but the sculpture is so much more like the astartes Alright, I take this back. After some research I saw that the species within the Clausinella genus have a very similar structure. So I'm more or less convinced that it's of this genus. Just gotta find a species that fits the time frame. About the rest (mainly #2, #4, and maybe #6) Today I was talking briefly to one of my fossil-friends, one who knows a lot about the Zandmotor (a fossil location in the NL, my usual hunting spot), and he said that he had found the same species of small gastropods there as I found. (FYI, the sediments we are talking about are the same: both sands from the North Sea, and, judging by the fossil evidence, from the same Eemian sediments). And he said that the gastropod species were mostly freshwater. But it wouldn't really make sense for freshwater species to be mixed within marine ones, so it is very possible that these shells aren't Eemian at all, and perhaps early Holocene (~ 8'000 ya) (when at the time the North Sea was mainly swampland).

Max-fossils Posted June 2, 2018 Author Share Posted June 2, 2018 @doushantuo thanks for the PDFs. They seem very interesting. I bookmarked them so that I can have a look at them later (need to focus on exams first) And my German is limited to "Gutentag" and "Ein brod und ein ei" (spelling is probably wrong too) So don't trouble yourself trying to find back that document. @ricardo yeah I do know that those are features that you have to look at first, before the sculpture. But when I was writing that message I was just trying to explain why my initial (rushed) thought was Astartidae. And thanks for the really nice pictures of the hinge teeth! Fantastic detail on them. Your photography skills are outstanding (presuming that you took the photos). Max Derème "I feel an echo of the lightning each time I find a fossil.

KimTexan Posted June 3, 2018 Share Posted June 3, 2018 You’re way over my heads and I don’t usualky try to go digging through primary journal papers for bivalves and gastropods. I admit to being lazy in the area of bivalve and gastropod ID. I do look at journals for cephalopods though. Since my reference books that have mollusks in them are limited I go here and get as close as I can. http://www.bagniliggia.it/WMSD/LfamilyA1.htm It is the Worldwide Mollusk Species Database The amount of data there is massive. There are over 142,000 species listed of both fossil and existant species. There are 10s of thousands of photos. Maybe one day it may be helpful. Also, if you’re on Facebook there is a very serious group of fossil gastropod enthusiasts and professionals who ID stuff there. It’s the Fossil Gastropod group.

Seems like a good website, I bookmarked it. Unfortunately I don't use Facebook. Luckily I've got you guys here on TFF, which are surely just as knowledgeable!

These are my first findings of fossil freshwater-shells, so I am quite happy with them. But there is still that big question mark on what their age is, as Eemian is not a possibility.
