Fig 30. Titanosaur caudal vertebrae from the Lower Member of the Bajo Barreal Formation in left lateral view, to demonstrate the diversity of these sauropods in this geologic unit.

Fig 30

Specimens were recovered from the Estancia Ocho Hermanos locality unless otherwise indicated. (A) Middle caudal vertebra of Andesaurus-like taxon (UNPSJB-PV 178, reversed and redrawn from Powell et al. [51]:fig. 1f). (B) Middle caudal vertebra of Andesaurus-like taxon (UNPSJB-PV 595, reversed and redrawn from Powell et al. [51]:fig. 1b). (C) Proximal (first and second) caudal vertebrae of Epachthosaurus sciuttoi (UNPSJB-PV 920, reversed and redrawn from Martínez et al. [67]:fig. 6a). (D) Middle (tenth) caudal vertebra of Epachthosaurus sciuttoi (UNPSJB-PV 920, redrawn from Martínez et al. [67]:fig. 8a). (E) Proximal caudal vertebra of indeterminate titanosaurian (UNPSJB-PV 876, redrawn from Powell et al. [51]:fig. 2a). (F) Proximal or middle caudal vertebra of indeterminate titanosaurian (UNPSJB-PV 182, redrawn from Powell et al. [51]:fig. 2e). (G) Middle caudal vertebra of indeterminate titanosaurian (UNPSJB-PV 730, redrawn from Powell et al. [51]:fig. 2g). (H) Proximal caudal vertebra of indeterminate titanosaurian (UNPSJB-PV 584, redrawn from Sciutto and Martínez [53]:fig. 4a). Unlike the others, the vertebra in (H) was collected from the Cañadón de Las Horquetas locality. Scale bars = 5 cm in A–B, E–G; 10 cm in C–D; 6 cm in H.
