Diagnosis
ReferenceDiagnosis
D. J. Chure et al. 2010A. mcintoshi is a titanosauriform sauropod based on the presence of camellate pneumaticity in its cervical vertebrae. It is diagnosed by a nasal lateral process directed anteriorly and lacking a posterior hook; maxilla narial process with dorsal articulation for the nasal; nasals overlap asymmetrically on the midline; external nares smaller than the orbit; upper crown apices shifted distally; upper tooth shafts twist through an arc of nearly 45°; and tooth wear present only mesially.
