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]
If the allosaurs' stress-fractures were caused by damage accumulating while walking or running this bone should have experience more stress-fractures than the others. The lack of such a bias in the examined Allosaurus fossils indicates an origin for the stress-fractures from a source other than running. The authors conclude that these fractures ...
Metriacanthosauridae fossils have only been found in modern Europe and Asia, parts of the prehistoric landmass Laurasia. From those found in Asia, most are from China, with a few discoveries in Thailand and other Asian countries. [clarification needed] The group is thought to have originated in Asia and spread westward to Europe.
The Ballad of Big Al, [a] marketed as Allosaurus [b] in North America, is a 2000 special episode of the nature documentary television series Walking with Dinosaurs. The Ballad of Big Al is set in the Late Jurassic, 145 million years ago, and follows a single Allosaurus specimen nicknamed "Big Al" whose life story has been reconstructed based on a well-preserved fossil of the same name.
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.
