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]
A. altai skeletal diagram, known portions in yellow. The holotype (PIN 3141/1) of Alioramus is a partial skull associated with three metatarsals.A joint Soviet-Mongolian expedition to the Gobi Desert in the early 1970s found these remains at a locality known as Nogon-Tsav in the Mongolian province of Bayankhongor, Nemegt Formation.
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 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. [2]
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 ...
Elway's final game minted him as an all-time great, Denver repeating thanks to an MVP effort (336 passing yards, TD pass, TD run) from its 38-year-old gunslinger. 44. XXVII (27, 1992) Cowboys 52 ...
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 ...
