Reptilia

Taxonomy
Uberabatitan ribeiroi was named by Salgado and Carvalho (2008). Its type specimen is CPPLIP-912, 1107, 1082 (left tibia, fibula, astragalus), a set of limb elements, and it is a 3D body fossil. Its type locality is BR-050 B (km 153), which is in a Maastrichtian channel sandstone in the Serra da Galga Formation of Brazil.

Diagnosis
ReferenceDiagnosis
L. Salgado and I. S. Carvalho 2008Titanosaur presenting the following autapomorphies: (1) anterior and mid-cervicals with postzygodiapophyseal lamina (podl) segmented in two unconnected laminae, zygapophyseal and diapophyseal, of which the zygapophyseal segment extends rostrodorsally over the diapophyseal; (2) mid-dorsals with a robust composite lateral lamina formed mainly by a diapophyseal lamina, probably homologous to the postzygodiapophyseal lamina and, to a lesser extent, by a relic of spinodiapophyseal lamina (spdl); (3) mid (and possibly posterior) dorsals with neural accessory laminae parallel to the prespinal lamina, which are probably the spinoprezygapophyseal laminae (sprl); (4) mid-caudal centra with deeply excavated lateral faces; (5) pubis notably thick and robust, with a very stout longitudinal crest on its external (ventral) face; (6) proximal end of the tibia with a very robust lateral protuberance that articulates with an equally robust medial knob of the fibula.
J. C. G. Silva Junior et al. 2019Salgado and Carvalho (2008) diagnosed U. ribeiroi based on a set of autapomorphic features, i.e.: (a) anterior and mid-cervical vertebrae with epipophyseal-prezygapophyseal lamina segmented in two unconnected segments, zygapophyseal and diapophyseal, of which the former extends anterodorsally over the latter; (b) mid-dorsal vertebrae with a robust composite lateral lamina formed mainly by a diapophyseal lamina, probably homologous to the postzygodiapophyseal lamina and, to a lesser extent, by a relic of the spinodiapophyseal lamina; (c) mid (and possibly posterior) dorsal vertebrae with neural accessory laminae parallel to the prespinal lamina, which are probably the spinoprezygapophyseal laminae; (d) mid-caudal centra with deeply excavated lateral surfaces; (e) pubis with a very stout longitudinal crest on its external (ventral) surface; (f) proximal end of the tibia with a very robust lateral protuberance that articulates with an equally robust medial knob in the fibula. In addition, a new autapomorphy is proposed here: astragalus with a well-developed anteroposterior crest that mediodistally delimits the tibial articulation.
