From the album: Russian Lower/Middle Oxfordian ammonites
Middle Oxfordian, densiplicatum zone, Shchurovo quarry, Moscow Oblast -
Hi all! This is a small trip report from a quarry by the town of Mikhaylov, Ryzan Oblast, situated in 200 km from Moscow. The place is very well known among the public interested in fossils, especially ammonite collectors. There are 4 quarries in a tight group, operated by different companies. Mikhaylov quarry is the most famous of them. The experience is very similar to that of other Callovian - Oxfordian quarries (in my previous reports), but ammonites suddenly take the place of gastropods! Pretty exciting, isn't it? Unfortunately there are not many spoil piles as Jurassic overburden is also used in production and taken to the plant. Another difference is that the site is overwhelmingly Callovian with little Oxfordian part. The ammonites are pyritized. What we see is usually the center of big specimens and small ones, large complete ammonites are preserved as imprints. We had prominent paleontologists in our group and the permission to visit most of the quarry. This trip took place in summer.
