Last Sunday we had a trip to the sandy quarry near St. Petersburg. Near of the sandy quarry there is a small village called "Novinka" (coordinates of this place on Google maps: 59.161362, 30.380684) Quarry near Novinka is a fairly large quarry, developed in the sands, introduced here in the Devonian (about 400 million years ago). The quarry is very picturesque and extremely interesting, there are mottled sands with a great variety of sedimentary textures deposited in various water conditions. During most of the Devonian Period, North America, Greenland, and Europe were united into a single Northern Hemisphere landmass, a minor supercontinent called Laurussia or Euramerica. We can say that the North America, Greenland and the north-western part of Russia were one territory. Here you can find many fossils of armoured prehistoric fish, as well as their teeth. A lot of paleo tourists from different countries come here in search of placoderms. We have a friend-professor of geology at the University of St. Petersburg. He said that last year a student from Japan went home with a necklace from the teeth of a armoured prehistoric fish. It was a very big paleontological luck. Next to the sand quarry are special designs for sifting sand. Large parts go in one direction, and fine sand in another. On photo few pieces of the shell of the fish (Asterolepis), which we found in 1 hour, and rock layers in sandy quarry. (Asterolepis is an extinct genus of antiarch placoderms from the Devonian of North and South America and Europe. They were heavily armored flat-headed benthic detritivores with distinctive jointed limb-like pectoral fins and hollow spine. The armor plate gives the Asterolepis a box-like shape. Its pectoral fins are also armored but the caudal and dorsal fin are not. The first fossils were named after M. Eichwald in 1840 after not star-like markings on the fossils.)
