Where Did Apatosaurus Live? In a 2012 study in the journal Functional Ecology, Wilkinson and his colleagues took another look at the theory, and concluded that it shouldn't be written off just yet. Early on, it was believed that Apatosaurus was too massive to support its own weight on dry land, so it was theorized that the sauropod must have lived partly submerged in water, perhaps in a swamp, but recent findings do not support this.

However, a 2013 study in the journal PLOS ONE looked at the neck flexibility of ostriches (the closest long-neck sauropod relative), and concluded that previous neck-flexibility models, which don't take into account the effect of soft tissues, cannot truly estimate the flexibility of sauropod necks — what this means for the actual posture and flexibility of Apatosaurus necks is unclear.
