Puertasaurus

Novas et al. 2005

Puertasaurus is a genus of sauropod dinosaur that lived in South America during the Late Cretaceous Period. It is known from a single specimen recovered from sedimentary rocks of the Cerro Fortaleza Formation in southwestern Patagonia, Argentina, which probably is Campanian or Maastrichtian in age. The only species is Puertasaurus reuili. Described by the paleontologist Fernando Novas and colleagues in 2005, it was named in honor of Pablo Puerta and Santiago Reuil, who discovered and prepared the specimen. It consists of four well-preserved vertebrae, including one cervical, one dorsal, and two caudal vertebrae. Puertasaurus is a member of Titanosauria, the dominant group of sauropods during the Cretaceous.

Skeletal restoration of Puertasaurus. The holotype, MPM 10002, consists of a cervical vertebra, a dorsal vertebra, and two unfigured caudal vertebrae. Missing elements were restored after Patagotitan, Futalognkosaurus, Notocolossus, and Tapuiasaurus. The human silhouette is from File:Silhouette of man standing and facing forward.svg (CC0). The total length of the sauropod is approximately 30 meters in this reconstruction, although the extremely incomplete nature of this taxon makes any size estimate exceedingly tenuous.
