#Archovember Day 21 - Yangchuanosaurus shangyouensis

While the three known species of Allosaurus were stalking across North America and Europe, China had its own top predator: the metriacanthosaurid carnosaur Yangchuanosaurus shangyouensis. Yangchuanosaurus even survived the Jurassic Allosaurus, living from the Middle Jurassic to the Early Cretaceous. Similar to Ceratosaurus, it had a bony ridge on its nose with multiple hornlets and ridges.

Like Allosaurus, Yangchuanosaurus was the apex predator at the time and would have had a similar diet of large dinosaurs like sauropods and ornithischians. They may have been pack hunters, as a single Yangchuanosaurus would have likely not been able to take down a sauropod alone. In the Shaximiao Formation, these would have been Protognathosaurus, Yuzhoulong, Omeisaurus, Datousaurus, Mamenchisaurus, Daanosaurus, and the club-tailed Shunosaurus. Ornithischian prey would have included stegosaurs like Huayangosaurus and Bashanosaurus, and neornithischians like Agilisaurus, Hexinlusaurus, and Xiaosaurus. Other theropods like Chuandongocoelurus, Xuanhanosaurus, Leshansaurus, Gasosaurus, and Kaijiangosaurus would have been both competitors and prey. It would have also lived alongside basal pterosaurs like Angustinaripterus, and pseudosuchians like Sunosuchus and Hsisosuchus. Life in the Suining Formation would have been similar, with the inclusion of the sauropod Qijianglong in the Early Cretaceous.

Shidaisaurus Jinae: tribute to Jin-Shidai company which owned a park near the site.

-A Metriacanthosaurid dinosaur from early to middle Jurassic China.

-Shidaisaurus was estimated at about 23 feet long and is the oldest allosauroid to date.

-The Holotype was a partial skeleton which lacked the majority of the tail vertibrate, pectoral girdle, and limb bones.

-I was unable to find a formal description of this animal or images of its bones, therefore I don’t think it has been formally described yet.
