Summary

Description
English: A size comparison between the sauropod dinosaur Cetiosauriscus stewarti and two humans.


• Cetiosauriscus is known from an incomplete skeleton, NHMUK R3078, which preserves a forelimb, a hindlimb, an ilium, and many tail vertebra. It is 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. However, this specimen shares no overlapping material with the type specimen and it is 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, mainly cetiosaurids. Due to the incompleteness of the remains and debate over which sauropod group Cetiosauriscus should belong to, the exact proportions could end up very different than show here. Sauropod neck length, for example, can vary a lot, even in closely related taxa.
• The humans are scaled to 170 cm and 160 cm.
