Tyrannosaurus [SEP] Earliest finds
gigas" remains were, in 1907, identified by Hatcher as those of a theropod rather than a ceratopsid. Henry Fairfield Osborn recognized the similarity between "Manospondylus gigas" and "T. rex" as early as 1917, by which time the second vertebra had been lost. Owing to the fragmentary nature of the "Manospondylus" vertebrae, Osborn did not synonymize the two genera, instead considering the older genus indeterminate. In June 2000, the Black Hills Institute found around 10% of a "Tyrannosaurus" skeleton (BHI 6248) at a site that might have been the original "M. gigas" locality.
