CM 307 in left lateral view. The series can be divided into midcaudal vertebrae (A–F), posterior caudal vertebrae (G–K), and distal caudal vertebrae (L–KK), following the definition of Tschopp et al. (2015a). Abbreviations: lr, lateral ridge; poz, postzygapophysis; prz, prezygapophysis; vlr, ventrolateral ridge. Modified from Holland (1906); no scale provided in original figure, but see table 3 for detailed measurements. referred to Diplodocinae indet. Most of the single vertebrae are relatively well preserved, but six elements were considerably reconstructed.
