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
Rhoetosaurus Rhoetosaurus Rhoetosaurus (meaning "Rhoetos lizard"), named after Rhoetus, a titan in Greek Mythology, is a genus of sauropod dinosaur from the Jurassic Hutton Sandstone of what is now eastern Australia. "Rhoetosaurus" is estimated to have been about long, weighing about . Subsequent authors have sometimes misspelled the name: "Rhaetosaurus" (de Lapparent & Laverat, 1955); "Rheteosaurus" (Yadagiri, Prasad & Satsangi, 1979). In 1924, Heber Longman, self-trained paleontologist at (and later director of) the Queensland Museum in Brisbane, learned of a large fossil reptile skeleton exposed in the Hutton Sandstone at the Durham Downs Station near Roma in central Queensland.
