Diagnosis
ReferenceDiagnosis
A. Pérez-Moreno et al. 2024Sauropod characterised by the following unique combination of char-acters and autapomorphies (marked with an asterisk): haemal canal approximately 25% of the total length of the chevron; humeral delto-pectoral attachment with prominent development; humeral lateral margin almost straight until the half-length or even more; humeral deltopectoral crest markedly expanded distally; humerus, strong pos-terolateral bulge around the level of the most distal portion of the deltopectoral crest; astragalus with symmetrical development of the articular surfaces, with the lateral surface for articulation of fibula and calcaneum as developed as the surface for the tibia (*); ratio of med-iolateral expansion of the tibia/tibial facet of the astragalus nearly 75% (*); astragalus with a hemispherical posterior bulge (*); astragalus without posterior fossa; mediolateral width of the astragalus four times its proximodistal height (*).
