Diagnosis
ReferenceDiagnosis
S. Apesteguía 2007Diplodocoid sauropod characterized by the following combination of features: mid to posterior dorsal vertebrae with extended lateral spinopostzygapophyseal laminae forming the lateral aspect of the neural spine, neural spine wider than anteroposteriorly extended (convergent with basal macronarians), additional lamina that reaches the postzygapophyses externalmost border like centropostzygapophyseal laminae, but departing from the middle of the extent of the centrodiapophyseal laminae and not from the centrum; centrodiapophyseal laminae with a branch that arises from its mid extension to reach the parapophysis, spinopostzygapophyseal lamina with a branch that arises at the distal region and is directed toward the postspinal lamina (as this not preserved, it is not possible to know if it reaches it), paired branches from the postspinal lamina directed laterally, non-hollow rhomboidal hyposphene.
