Discovery and naming

The holotype, GPIT-PV-30787, also known as "GPIT IV", is a partial postcranial skeleton. It was discovered in 1922 and stored in the paleontological collection of the university of Tübingen. It was originally assigned to the species ''

Gresslyosaurus ''Gresslyosaurus'' (meaning "Amanz Gressly's lizard") is a genus of plateosaurian sauropodomorph dinosaur that lived during the Late Triassic period, around 214 to 204 million years ago, in Switzerland. Taxonomy ''Gresslyosaurus'' was originally ...

Later, it was considered an exemplar of ''Plateosaurus'', sometimes being used as reference materials for phylogenetic analyses using its name. However, it actually contains several features with more derived sauropodomorphs, which allowed it to be named as the distinct taxon ''Tuebingosaurus maierfritzorum'' in 2022. The generic name, "''Tuebingosaurus''", honors the city of Tübingen while the specific name, "''maierfritzorum''", refers to both Uwe Fritz and Wolfgang Maier; the former is an editor at the journal '' Vertebrate Zoology'' which hosted a ''
