RuMert Posted June 27, 2021 Share Posted June 27, 2021 (edited) Hi all! This is another report from Oxfordian quarries in the vicinity of Moscow. Previous 1 (Peski) Previous 2 (Timonino) Peski again. If you read my fossil sites overview, you know that Peski quarry is a unique site where you could find lots of Carboniferous fossils, Middle Jurassic dinosaurs, calcitic Callovian ammonites and very good Oxfordian gastropods. The latter are the most numerous and easier to search for. My trip took place in April and was mostly a success with a good variety of finds Edited June 27, 2021 by RuMert 4 My sites & reports Link to comment Share on other sites More sharing options...
RuMert Posted June 27, 2021 Author Share Posted June 27, 2021 (edited) The gastropods are mostly found on spoil pile slopes, uncovered by rains and snow melting. These are the main slopes with grey Oxfordian clay Smaller spoil piles in the north of the quarry View of the functioning part of the quarry Edited June 27, 2021 by RuMert 7 My sites & reports Link to comment Share on other sites More sharing options...
RuMert Posted June 27, 2021 Author Share Posted June 27, 2021 (edited) Searching conditions In this picture there are about 10 gastropods. Can you spot them all? Edited June 27, 2021 by RuMert 5 My sites & reports Link to comment Share on other sites More sharing options...

RuMert Posted June 27, 2021 Author Share Posted June 27, 2021 (edited) Everything is 10 mm or less. Bigger are Bathrotomaria gastropods, Callovian belemnites (quite large) and Gryphea oysters. Also present are Cyclocrinus stem fragments, small belemnites, scaphopods and echinoid spines. Oxfordian ammonites are not preserved Edited June 27, 2021 by RuMert 8 My sites & reports Link to comment Share on other sites More sharing options...

Ludwigia Posted June 27, 2021 Share Posted June 27, 2021 The gastropods and bivalves are certainly well preserved for the Oxfordian. 2 Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...

FossilDAWG Posted June 27, 2021 Share Posted June 27, 2021 What a remarkable place! So many ages of fossils. I really really like those Oxfordian fossils. Small is OK, they are exquisitely preserved and the diversity is remarkable. Thanks for showing us! I would love to spend a day (or more) there.

pachy-pleuro-whatnot-odon Posted June 27, 2021 Share Posted June 27, 2021 5 hours ago, Ludwigia said: The gastropods and bivalves are certainly well preserved for the Oxfordian. I agree. Some of them are reminiscent of gastropods I've found in the Paris-basin - including state of preservation. But those are Eocene shells...! In my experience, these shells are pretty well-preserved for the Jurassic All in all another great report! Too bad there were no marine reptiles, but very interesting to see some of your other hunting grounds. So: thanks! 1 '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...
RuMert Posted June 28, 2021 Author Share Posted June 28, 2021 (edited) Thank you, preservation is indeed the main feature of this site. We encounter the same gastropods and bivalves in various other locations, but only here we see how they actually look (and feel as they are pretty sturdy) Edited June 28, 2021 by RuMert My sites & reports Link to comment Share on other sites More sharing options...
Nimravis Posted June 28, 2021 Share Posted June 28, 2021 Love the pictures of the the area you collect, but I really love your finds and the pictures that you took of them. 1 Link to comment Share on other sites More sharing options...
