Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| S. Apesteguía 2004 | Bonitasaura differs from other titanosaurs in the following combination of features: dentary alveoli reduced in number (three in the main ramus, one in the angle, and up to seven in the anterior region); middle and posterior region of the dentary edentulous and forming a sharp dorsal edge, with a profusely vascularized lateral side; very robust, diagonal neural arch pillars and bulging neural spine summits on anterior dorsal vertebrae. More diagnostic characters might emerge once all of the postcranial material has been prepared. | |
| P. A. Gallina and S. Apesteguía 2011 | Bonitasaura salgadoi differs from other titanosaurians in possessing the following unique combination of features: frontal outer rim straight (not sigmoid); thin and enlarged maxillary process of the lacrimal oriented downward and forward; posterior region of the dentary edentulous and bearing a sharp dorsal edge, with a profusely vascularized lateral surface; tongue−like process on spinoprezygapophyseal laminae of mid−cervical vertebrae; very robust, diagonal neural arch pillars and bulging neural spine summits on anterior dorsal vertebrae; longitudinal, paired fossae on the sides of the prespinal lamina in anterior dorsal vertebrae; circular, vertically oriented fossae aligned with the prespinal lamina in mid−dorsal vertebrae; thin, longitudinal laminae diverging from prespinal and postspinal laminae in anterior caudal vertebrae; anterior, longitudinal ridge of the tibia with marked promontory just over the anterior process of distal end | |
| P. A. Gallina and S. Apesteguía 2015 | Bonitasaura salgadoi differs from other titanosaurs in possessing the following unique combination of features (autapomorphies marked with an asterisk): frontal outer rim straight (not sigmoid); thin and enlarged maxillary process of lacrimal oriented downward and forward (*); posterior dentary edentulous, with sharp dorsal edge, and highly vascularized lateral surface (*); ventral longitudinal keel in posterior half of axial centrum (*); tongue-like process on spinoprezygapophyseal laminae of mid-cervical vertebrae (*); very robust, diagonal neu- ral arch pillars and bulging neural spine summits on anterior dorsal vertebrae; longitudinal, paired fossae on sides of anterior median lamina in anterior dorsal vertebrae; circular, vertically oriented fossae aligned with anterior median lamina in mid-dorsal vertebrae (*); thin, longitudinal laminae diverging from anterior median lamina and postspinal laminae in anterior caudal vertebrae (*); anterior, longitudinal ridge of the tibia with marked promontory just over anterior process of distal end (*). |
