Allosaurus size comparison
A size comparison of various specimens of the theropod dinosaur genus Allosaurus.
- • Silhouettes are based on Allosaurus skeletal reconstructions by Scott Hartman [2] and Henrique Paes [3], used with permission. I, the author, require that Scott Hartman, Henrique Paes and steveoc 86 at Wikimedia Commons get attribution.
- • AMNH 4734, DINO 2560 (UUVP 6000), and MOR 693 are scaled using the scale bars in their respective reconstructions. The average size of adult Allosaurus fragilis specimens are estimated at ~8.5 m [1]. DINO 11541 is based on figures 3 and 4 in Chure et al. (2020). Allosaurus europaeus, ML 415, is scaled to ~7 m based on an estimate by Greg Paul,[2] the skull scaled based on figure 16 in Chure et al. (2020). SMA 0005 silhouette based on Fig 1 in Foth et al. (2013) with some details from images of the mount online, scaled to about 7.6 m.[3][4]
- • The holotype of Allosaurus fragilis YPM 1930 is considered undiagnostic, and because of this, a more complete specimen from the same quarry, AMNH 4734, was proposed as a neotype for the species.[5][6] DINO 2560 is often referred to Allosaurus fragilis. In 2020, Allosaurus jimmadseni was described with DINO 11541 designated the holotype, SMA 0005 and MOR 693 were referred to the species.[7]Allosaurus europaeus, ML 415, is only known from one fragmentary specimen consisting of a partial skull, ribs and a few cervical vertebrae;[8] the silhouette above hypothetical should be viewed with caution.
- • Fragmentary allosaur material, which was named Epanterias, may belong to Allosaurus suggesting the genus could grow larger. Epanterias has been estimated 12 to 13 m.[9][10][11] A large allosaurid Saurophaganax is also considered a species of Allosaurus by some researchers (Allosaurus maximus).[12][2]
- • Humans are scaled to 170 cm (5 ft 7 in) and 160 cm (5 ft 3 in).

AllosaurusAllosaurus byl popsán slavným americkým paleontologem z 19. století Othnielem Charlesem Marshem v roce 1877. Byl relativně blízkým příbuzným gigantických karcharodontosauridů, jejichž nejznámějšími zástupci jsou Giganotosaurus carolinii a Mapusaurus roseae, který byl popsán Coriou a Curriem v roce 2006 (oba z podčeledi Giganotosaurinae, vytvořené při popisu mapusaura. Nejužší společný klad, který zahrnuje alosaura s karcharodontosauridy je nadčeleď Allosauroidea. .. pokračovat ve čtení
