Herbstosaurus Herbstosaurus Herbstosaurus is the name given to a genus of pterosaur that lived during the Jurassic period, in what is now Argentina. In 1969 Argentine paleobotanist Rafael Herbst in the province Neuquén at Picun Leufú dug up a piece of sandstone holding a number of disarticulated bones of a small reptile. At the time it was assumed the rock dated from the Middle Jurassic (Callovian), about 163 million years ago. In 1974/1975 paleontologist Rodolfo Magín Casamiquela named the find as a new genus. The type species is "Herbstosaurus pigmaeus". The genus name honours Herbst and connects his name to Greek
Upper Jurassic deposits of Gorodishchi and Cretaceous fossils. The layers consistently leaning against each other contain valuable information about evolution between the two geological periods: Jurassic and Cretaceous. Upper Jurassic deposits of Gorodishchi The Exposed Upper Jurassic deposits () near the village of Gorodischi, Ulyanovsk Oblast on the right bank of Kuybyshev Reservoir is one of the protected areas of Ulyanovsk Oblast. The Gorodishchi exposure is within the Ulyanovsk paleontology zakaznik. It is scientifically valuable as a basal section Upper Jurassic adjournment on Russian Platform. Many fossils have been recovered from it, including vertebrae of ichthyosaurs and plesiosaurs, and mollusc shells. The Cambrian deposits are
