Hi everyone! Oxfordian again This time it's the turn of small shells from Peski Quarry, located some 80 km south-east of Moscow. It's something like the Moscow region's Jurassic gastropod heaven. For some geologic reasons, ammonites do not get preserved there while little gastropods and bivalves do. It's also the only place dinosaurs were found in the Moscow region. As of today the continental sediments are depleted, but the marine ones are stil abundant. The quarry extracts Carboniferous limestone, removing Callovian marl and Oxfordian clay. The clay is then discharged in open piles - small shells of exceptional quality are washed up during rains. Below are pictures from two trips: one in winter (with snow) and one recently. To get to the Jurassic part of the quarry fastest you have to go through woods along a small river:
