Diagnosis
ReferenceDiagnosis
A. Averianov and V. Efimov 2018Referred to Titanosauriformes based on the neural arch of anterior and middle caudal vertebrae positioned at the anterior half of the centrum. Referred to Titanosauria based on the procoelous anterior and middle caudal vertebrae with strongly convex condyle, somphospondylous (camellate) bone texture of caudal vertebrae, and hyposphenal ridge absent. Referred to the Lithostrotia based on a distinct rim ringing the condyle in middle caudal vertebrae. Among lithostrotians (sensu González Riga et al., 2108) it differs from Malawisaurus, Tengrisaurus, Rapetosaurus, Aeolosaurus and Saltasauridae by a ventral ridge instead of a ventral groove in anterior and middle caudal vertebrae, from Malawisaurus and Saltasauridae ― by the lack of ventrolateral ridges in anterior and middle caudal vertebrae, from Epachthosaurus and more derived lithostrotians ― by the lack of tubercle on the dorsal surface of the transverse process in the first caudal vertebra. It differs from all sauropods except Astrophocaudia and Epachthosaurus by hyposphene-hypantrum articulations in anterior caudal vertebrae.
