RuMert Posted February 18, 2023 Share Posted February 18, 2023 (edited) Hi all! As you could know from my previous reports we have several mid-Oxfordian sites around Moscow, which are not the best ammonite-wise, but yield well-preserved gastropods and bivalves. Shchurovo quarry is one of the best thanks to its enormous spoil piles and less popularity among hobbyists. It's situated in the outskirts of the historic city of Kolomna, one of the preferred Muscovites' weekend destinations (also home to pastila if you know what it is). The quarry is situated some 100km from Moscow. Kolomna old center: Main buildings are made from the local limestone.

RuMert Posted February 18, 2023 Author Share Posted February 18, 2023 (edited) Such limestone was used to build white-stone pre-imperial Moscow. The quarry was once a source of local carboniferous trilobites: Trilobites are rare though, you can see mostly brachiopods and corals Edited February 18, 2023 by RuMert 8 My sites & reports Link to comment Share on other sites More sharing options...

pachy-pleuro-whatnot-odon Posted February 18, 2023 Share Posted February 18, 2023 Great little trip report, Yury! Beautiful looking town and giant quarry! Some really nice finds too! Especially love the echinoderm spine!

They look extremely similar, both in morphology and in preservation, to gastropod shells I've found from the Eocene of the Paris Basin when I was still a child...! Guess there's only just so much morphospace for gastropod shells to evolve into... Thanks for sharing!

Not the best specimen, but hopefully enough to give you an impression...

RuMert Posted February 20, 2023 Author Share Posted February 20, 2023 Good that many ancient gastropod taxons are still alive today like apporhaids, mathildids, pleurotomarids, ampullarids etc. you can even keep some of them in your aquarium 2 My sites & reports Link to comment Share on other sites More sharing options...
