During the 1960s–1970s, remains of Pterodaustro guinazui were discovered for the first time in the Lagarcito Formation by José Bonaparte.
Since then, the fossil site, named Loma del Pterodaustro during the 1990s, has been extensively quarried, providing abundant fossil plant and animal remains, mainly pterosaurs; due to the fine preservation of delicate structures, the site has been classified as a Konservat-Lagerstätte.
