Cetiosauriscus-Scale-Diagram-SVG-Steveoc86

• Cetiosauriscus is known from an incomplete skeleton NHMUK R3078 preserving a forelimb, a hindlimb, an ilium and many tail vertebra. It's uncertain what type of sauropod Cetiosauriscus was; it was originally placed as a cetiosaurid and by later researchers as a basal diplodocid and others as a mamenchisaurid. A second specimen NHMUK R1967 has been referred to C.stewardti, consisting of a whip-lash tail, a trait known in diplodocids. This specimen, however, shares no overlapping material with the type specimen and it's uncertain that it belongs to the species. Tschopp et. al. 2015 in specimen level anaylsis rejected Cetiosauriscus as a diplodocid and found it more likely to be close to Mamenchisaurus or Omeisaurus. ^[1]

• The silhouette shown here is based on: ^[2][3] with unknown parts inspired by other sauropod reconstructions. Due to the incompleteness of the remains and debate over which sauropod group Cetiosauriscus should belong to, the exact proportions are uncertain. Sauropod neck length can vary a lot, even in closely related taxa, it's therefore possible it could be longer or shorter than shown here.

• The humans are scaled to 170 cm and 160 cm.
