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

The gastropods are mostly found on spoil pile slopes, uncovered by rains and snow melting. These are the main slopes with grey Oxfordian clay

In this picture there are about 10 gastropods. Can you spot them all?

Everything is 10 mm or less. Bigger are Bathrotomaria gastropods, Callovian belemnites (quite large) and Gryphea oysters.

The gastropods and bivalves are certainly well preserved for the Oxfordian.

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.

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 :o

 

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! :D

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)
