|---|---|---|
| R. D. F. Martínez et al. 2016 | Basal lithostrotian titanosaurian sauropod diagnosed by the following autapo- morphies: (1) maximum (rostroventral—caudodorsal) diameter of orbit nearly 40% rostro-caudal length of cranium (as measured from tip of snout to occipital condyle); (2) complex maxilla—lacrimal articulation, with ascending ramus of maxilla embedded in and bordered laterally and medially by lacrimal dorsal process; (3) medial edge of caudal sector of maxillary ascending ramus bordering bony nasal aperture with low but well-defined ridge; (4) ‘tongue-like’ ventral process of quadratojugal that overlaps quadrate caudally; (5) separate foramina for all three branches of the trigeminal nerve; (6) absence of median venous canal connecting infundibular region to ventral part of brainstem; (7) premaxillary teeth subvertical, maxillary teeth procumbent, and dentary teeth recumbent; (8) middle cervical vertebrae with ‘strut-like’ (as opposed to ‘sheet-like’) centroprezygapophyseal laminae; (9) extremely elongate and slender ossified tendon extending along cervical series ventrolateral to vertebrae and ribs |
