Tyrannosaurus rex Osborn, 1905
Tyrannosaurus rex is known from more good skeletons than almost any other large Mesozoic theropod, and the individuals differ enough in size, build, completeness, and age at death that no single drawing speaks for the species. This hub gathers several documented specimens here, so you can compare and contrast size, femur length or check out individual reconstructions.
Pick a specimen below to see its own reconstruction, its known material, and its record — or scan and sort the table for how they stack up by size and completeness. The holotype, CM 9380, anchors the species; the more complete skeletons, from Sue to Scotty, fill in details earlier specimens lacked.
