摘要
[编辑]描述Pellegrinisaurus Skeletal V1.svg |
English: Pellegrinisaurus powelli is a species of titanosaurian sauropod dinosaur from the late Upper Cretaceous of Argentina (Allen Formation). The type and only specimen of Pellegrinisaurus is MPCA 1500, which consists of four dorsal vertebrae, a partial femur, and 26 caudal vertebrae. Only one of the partial dorsals is figured, and it is not specified which one it is, so it has been omitted in this version.[1]
A phylogenetic analysis conducted by Bandeira et. al., 2016, recovered Pellegrinisaurus as a basal member of the lineage of titanosaurs leading towards Saltasauridae.[2] Another analysis run by Sallam et. al., 2018, recovered it as the most basal taxon in a clade consisting of it, Dreadnoughtus, Barutitan, and Alamosaurus.[3] Currently, different studies often have quite different topolgies,[4] so the position of Pellegrinisaurus may be elsewhere. The femur of Pellegrinisaurus is not illustrated in lateral view. Based on the shape of the known material, it most resembles that of Petrobrasaurus in shape.[4] The lateral view was based on a combination of that of Petrobrasaurus[5] and Dreadnoughtus, modified to match the femoral length of Pellegrinisaurus.[6] The silhouette is based on Dreadnoughtus,[6] with the neck reconstructed after Futalgonkosaurus[7] and the skull is based on Tapuiasaurus.[8] References
