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.
