Gondwanatitan (meaning "giant from
The type species is Gondwanatitan faustoi, formally described by Kellner and de Azevedo in 1999.
Etymology
Gondwanatitan means "Gondwana Titan", and is named after Gondwana, the supercontinent that the genus' South American range was once part of, and the Titans of classical Greek mythology. The type and only named species, G. faustoi, is a patronym honoring Dr. Fausto L. de Souza Cunha, a former curator at the Museu Nacional/UFRJ who led the excavation of the type specimen.[1]
Description
Gondwanatitan was a fairly small sauropod, only 7 meters (23 ft) long and weighing about 1 tonne (1.1 short tons).[2] It had relatively gracile limb bones.[1] The middle caudal vertebrae are distinctively "heart-shaped", which allows isolated caudal vertebrae to be easily distinguished from those of Aeolosaurus.[3]
The vertebrae from the middle part of its tail had elongated
Classification
Gondwanatitan is a member of the clade
Provenance
The type specimen of Gondwanatitan faustoi was found in strata of the Adamantina Formation.[1] Other material assigned to the genus has been found in the Cambabe Formation.[5]
History
The type specimen of Gondwanatitan faustoi was discovered in 1983 on the farm of Yoshitoshi Myzobuchi in São Paulo, Brazil.[1] The specimen was excavated between 1984 and 1986, but preparation work on the specimen did not begin in earnest until 1997. It was finally described as a new genus and species in 1999. In 2001, G. faustoi was briefly transferred to the genus Aeolosaurus, making Gondwanatitan a junior synonym of that genus, but it has since been widely regarded as separate.[7][8]
