Yangchuanosaurus is an extinct genus of metriacanthosaurid theropod dinosaur that lived in China from the Middle Jurassic to Late Jurassic periods (Bathonian to Tithonian stages), and was similar (although slightly larger) in size and appearance to its North American and European relative, Allosaurus. Yangchuanosaurus hails from the Upper ...
The dentition of Sinraptor was very similar to that of Allosaurus and indicated that it likely would have preyed upon medium-sized dinosaurs such as stegosaurs by using its blade-like teeth to inflict massive, fatal wounds. [6] Sinraptor hepingensis, formerly referred to Yangchuanosaurus, is a second species referred to this genus. [1]
Allosaurus was a large bipedal predator for its time. Its skull was light, robust, and equipped with dozens of sharp, serrated teeth. It averaged 8.5 meters (28 ft) in length for A. fragilis, with the largest specimens estimated as being 9.7 meters (32 ft) long. Relative to the large and powerful legs, its three-fingered hands were small and ...
Carrano, Benson & Sampson (2012) noted that the name Metriacanthosauridae should be used as it has priority over Sinraptoridae. [4] Cladistically, Sinraptoridae had been latest defined in 2005 by Paul Sereno as the most inclusive monophyletic group that contains Sinraptor dongi and all species closer to Sinraptor than to either Allosaurus fragilis, Carcharodontosaurus saharicus, or the house ...
The skull also exhibits features consistent with significant cranial kinesis: a synovial joint between the braincase and the frontals and a loose articulation between the dentary and the angular/surangular. [5] This cranial kinesis would have dampened forces on the bones of the skull and allowed allosaurids to open their mouths to very large ...
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 ...

The holotype of Metriacanthosaurus parkeri, specimen OUM J.12144, was discovered in 1871 by W. Parker at Jordan's Cliff, Weymouth, [1] and the specimen includes an incomplete hip, a leg bone, and part of a backbone; the geologist John Phillips briefly commented on the specimen during the same year.
