Description: Skull of Tyrannosaurus rex, type specimen (CM 9380) at the Carnegie Museum of Natural History (abbreviated as CMNH). The American Museum of Natural History (AMNH) had led the expedition which had found the fossil in 1902 and thus the AMNH possessed the mount until 1941, when it was purchased by the Carnegie Museum. The latter changed the original inventory number AMNH 973 to the current CM 9380. The skull is largely incomplete and in the AMNH, between 1902 and 1915, the remains were heavily and inaccurately restored with plaster using Allosaurus as a model (Allosaurus was the largest theropod known in the 1900s and 1910s, assuming at the time it was the closest relative to Tyrannosaurus). The historic restoration that the AMNH brought to this skull, as it can be seen in this photograph, was disassembled in 2003, but photographer John Parise, from San Francisco (USA), took this photograph in the Carnegie Museum in 2001 and shared it in Commons and Flickr in 2006. The process to reassemble the skull required elements from other skulls, casts provided by other museums in the United States. It was finally put on display in a more accurate anatomical restoration in 2008.
