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

Hi all! Today I'd like to introduce you to another place to hunt for small Oxfordian fossils, a quarry by the village of Timonino, located to the east of Moscow. The finds and hunting method are pretty much the same as in the previous site. Basically, surface collecting small Oxfordian fossils, usually gastropods, is a distinct sort of fossil hunting in the Moscow region. To the east of the city lies a sort of "Oxfordian belt" with similar geologic setting, finds and hunting conditions. Here's a map of the Oxfordian sites in the region. The quarries in operation are marked in blue, they usually extract older layers, thus removing Oxfordian clay and stacking it in spoil piles. Fossils can then be collected from the piles' surface. Due to specific conditions, ammonites are not preserved at all, but bivalves and gastropods retain a very good quality. People usually search for the latter. Most such quarries are located around the city of Kolomna, including Peski quarry I've already presented. Shchyolkovo quarry (in brown) is out of operation and completely flooded, but there are a couple of tiny clay patches with mostly belemnites. A group of sites marked in orange are located on the Moskva river bank and accessible only in winter (focus of the Frozen fossils topic), the hunting season is about to resume. They are also Oxfordian with the same set of gastropods, but also well-preserved ammonites everybody looks for. Timonino quarry is an isolated site with conditions similar to Kolomna's. Unlike the latter, it strangely extracts white Bathonian clay instead of limestone. The quarry came in operation just a few years ago and ultimately became popular among fossil collectors. Going forward I can say its reputation is greatly exaggerated.
