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
Gasosaurus Gasosaurus Gasosaurus () () is a genus of tetanuran theropod that lived approximately 171.6 to 161.2 million years ago during the middle of the Jurassic Period. The name ""Gasosaurus"" is derived from the English ""gasoline"" and the Greek σαῦρος/sauros ("lizard / generic reptile"). Only one species is currently recognised, "G. constructus", from which the specific name honours the gasoline company that found the Dashanpu fossil quarry in Sichuan Province, China, now named as the Lower Shaximiao Formation. The first and to date only fossils, albeit postcranial (missing the skull), were recovered in 1985 during the construction of a gas facility,
