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
Macrurosaurus Macrurosaurus Macrurosaurus (meaning "large-tailed lizard") is the name given to a genus of dinosaur from the Early Cretaceous. It was a titanosauriform which lived in what is now Europe. The genus "Macrurosaurus" was named by Harry Govier Seeley in 1869 but not yet described so that it remained a "nomen nudum". In 1876 Seeley described the type species, "Macrurosaurus semnus", making the name valid. No other species are known. The generic name is derived from Greek "makros", "large", and "oura", "tail". The specific name is derived from Greek "semnos", "stately" or "impressive". The holotype of "Macrurosaurus", SM B55630, consists of
