Diagnosis
ReferenceDiagnosis
P. C. Sereno et al. 1999Rebbachisaurid characterized by elongate frontal (much narrower than long) with a marked cerebral fossa on the frontal, transversely oriented upper and lower tooth rows, extension of the tooth rows lateral to the plane of the principal ramus of the lower jaw, tooth crowns with prominent medial and lateral marginal ridges, dorsal vertebrae with paired pneumatic spaces at the base of the neural spines, and a prominent rugosity on the medial aspect of the base of the scapular blade (Fig. 2E, ru).
P. C. Sereno and J. A. Wilson 2005Rebbachisaurid sauropod characterized by five accessory fenestrae in the jugal, surangular, and angular; tooth number increased to 20 and to 34 in the maxilla and dentary, respectively; tooth replacement increased to as many as 10–12 in a single column; premaxilla and dentary lacking alveolar septa; maxilla with oval (vertically elongated) replacement foramina; extension of the dentary tooth row lateral to the sagittal plane of the lower jaw; subcircular mandibular symphysis; crowns with prominent mesial (medial) and distal (lateral) ridges; scapula with prominent rugosity on the medial aspect of the proximal end of the blade.
