Description

ALAMOSAURUS SANJUANENSIS

Alamosaurus sanjuanensis was named on the basis of a holotypic scapula and paratypic ischium from the Maastrichtian Kirtland Formation of New Mexico, USA (Gilmore, 1922). Referred remains from Utah (Gilmore, 1946) and Texas (Lehman & Coulson, 2002) are substantiated by autapomorphies amongst the exemplars (D’Emic et al., 2011) and were included in scoring for Alamosaurus. Teeth (Kues, Lehman & Rigby, 1980) and a pes (D’Emic et al., 2011) from the holotypic area and horizon were also included in the scoring for Alamosaurus because they most likely pertain to Alamosaurus, the only sauropod genus recognized from the Maastrichtian of North America.
