Tyrannosaurus rex skeletal diagram (CM 9380)

The rigurous and fully restored skeletals of CM 9380, originally labeled as AMNH 973 and described by Osborn in 1905 and 1906. It was sold to CM during second world war, in fear that a japanese attack to New York could destroy all Tyrannosaurus specimens. It is the holotypic specimen , so it is the one the species was named after and Tyrannosaurus rex by definition, all of the other specimens are referred to the species. The mounted skeleton is based to a great degree in AMNH 5027, and carries several innacuracies from the time it was assambled that are very hard to correct. It is exhibited at the Carnegie museum of Natural history.

Including GDI with top view of FMNH PR 2981 scaled down to match the measurements reported for CM 9380 in Osborn 1915.

12/11/2018: Updated basically everything. Mass will probably need to be tweaked in the future.

01/07/2020: Updated the dorsal series neural arches to be in line with detail shown in other reconstructions; same goes for the pelvic girdle. Added furcula and hyoid.
