|---|---|---|
| L. S. Filippi et al. 2024 | Is a titanosaurian sauropod characterized by a series of autapomorphic characters (marked with *) and a unique combination of 135 characters: (1)* posterior region of skull rotated posteroventrally so that it is on the same level as the snout; (2)* foramen magnum located subparallel to the tooth row; (3) spatulate snout, generated by lateral expansion of the maxillae and dentaries; (4)* ridge at the contact between the ascending process and the body of the premaxilla, which generates a prominence in lateral view; (5) jugal with a highly elongated maxillary process and a wide and ventrally extended quadratojugal process, (6)* a double lateral temporal fenestra formed by an anterior subcircular and a posterior enlarged and laterally compressed opening; (7) quadrangular jaw with highly developed lateral expansion; (8) dentition restricted to the most anterior border of the maxillae and dentaries; (9) anteroposteriorly short jaw that represents half of the total skull length; (10)* jaw highest point, twice the height of the dentary, located in the articular sector between the coronoid process and surangular; (11) short and slender neck, integrated by 12 cervical vertebrae; and (12) anteroposteriorly long and dorsoventrally low ilium. |
