Garrigatitan (meaning "garrigue giant") 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.[1]
Discovery and naming
[edit]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 along with the remains of Atsinganosaurus, another titanosaurian.[2]
In 2021, 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]
Additional fossil material has been assigned to the species including a cervical vertebra, two humeri, a left ilium, and a right ischial bone. Other specimens recovered include a neural spine, a right humerus, part of the right leg, and a left femur. The assigned specimens come from the third level of the second series. The fossils were found within 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. They are all part of the Moulin Seigneurial de Velaux collection.[1]
The generic name, "Garrigatitan," is a combination of the Occitan "garriga," meaning "dry thicket", referring to a type of Mediterranean vegetation characterized by drought-resistant shrubs, and the Greek "titan", after the Greek mythological family of giants. The specific epithet, "meridonalis," means "southern" in Latin, in reference to the discovery location in southern France.[1]
Description
[edit]Some Garrigatitan specimens regarded as subadults or adults belonged to individuals measuring 4–6 metres (13–20 ft) long and weighing 2–2.5 metric tons (2.2–2.8 short tons). A tentatively referred specimen belonged to an adult individual measuring about 12–16 metres (39–52 ft) long.[1]
Classification
[edit]Cladistic analysis of Garrigatitan shows that it belonged to the subfamily Lirainosaurinae.[1]
