Garrigatitan (meaning "garrigue giant", referring to a type of Mediterranean vegetation characterized by drought-resistant shrubs) is a genus of titanosaurian dinosaur from the late Cretaceous Period of the Grès à Reptiles Formation in France. The genus contains a single species, Garrigatitan meridionalis. The subadult length is estimated to be 4–6 metres (13–20 ft), while the adult length is estimated at around 12–16 metres (39–52 ft).[1]
Discovery and naming
Between 2009 and 2012, excavations were carried out at Velaux-La Bastide Neuve by the Palaios Association and the University of Poitiers. During the excavations, the holotype of Garrigatitan was discovered and remains of Atsinganosaurus velauciensis were also present.[2]
In 2020, the type species Garrigatitan meridionalis was named and described by Verónica Díez Díaz, Géraldine Garcia, Xabier Pereda Suberbiola, Benjamin Jentgen-Ceschino, Koen Stein, Pascal Godefroit and Xavier Valentin. The holotype, MMS / VBN.09.17, was found in a layer of sandstone of the Begudian, the second level of the second series, dating back to the late Campanian. It consists of a sacrum belonging to an immature individual.[1]
In addition, a number of other fossils have been assigned to the species. This concerns the specimens MMS / VBN.02.99: a cervical vertebra; MMS / VBN.09.A.016 and MMS / VBN.09.47: two humeri; MMS / VBN.12B.12a: a left ilium and MMS / VBN.12B.12b: a right ischial bone. Furthermore, fossils were allocated with reservation. They were the specimens MMS / VBN.12B.011: a neural spine; MMS / VBN.12.82: a right humerus; MMS.VBN.09.A.017: part of the right leg and MMS / VBN.00.13: a left femur. The assigned specimens come from the third level of the second series. The fossils were found in a lens with an area of 375 square meters and a thickness of 1.2 metres (3.9 ft). They were not associated and presumably represent different individuals and they are all part of the Moulin Seigneurial de Velaux collection.[1]
Etymology
The genus name is a combination of the Occitan garriga, "dry thicket", and the Greek "titan", a member of a mythological family of giants. The species epithet meridonalis means "southern" in Latin.[1]
