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
Gregory (given name) one of the Three Hierarchs (Ancient Greek: Οἱ Τρεῖς Ἱεράρχαι; Greek: Οι Τρεις Ιεράρχες). The other two are Basil the Great, also known as Basil of Caesarea and John Chrysostom. All three have separate feast days in January: Basil on January 1, Gregory on January 25, and Chrysostom on January 27. Gregory (given name) The masculine first name Gregory derives from the Latin name "Gregorius", which came from the late Greek name "Γρηγόριος" (Grēgorios) meaning "watchful, alert" (derived from Greek "γρηγoρεῖν" "grēgorein" meaning "to watch"). Through folk etymology, the name also became associated with Latin "grex" (stem "greg–") meaning "flock"
