Yunyangosaurus (meaning "Yunyang County lizard") is a genus of possible megalosauroid dinosaur from the Xintiangou Formation in Chongqing, China.The type and only species is Yunyangosaurus puanensis. [1]
The Lufeng Formation (formerly Lower Lufeng Series) is a Lower Jurassic sedimentary rock formation found in Yunnan, China.It has two units: the lower Dull Purplish Beds/Shawan Member are of Hettangian age, and Dark Red Beds/Zhangjia'ao Member are of Sinemurian age. [1]
Size is an important aspect of dinosaur paleontology, of interest to both the general public and professional scientists. Dinosaurs show some of the most extreme variations in size of any land animal group, ranging from tiny hummingbirds , which can weigh as little as two grams, to the extinct titanosaurs , such as Argentinosaurus and ...
In 2019, Mannion e.a. indicated two distinguishing traits. They were autapomorphies, unique derived characters.In the vertebrae positioned at the transition between the tail base and the middle tail, the lower ends of the laminae spinoprezygapophyseales, the ridges running from the neural spine towards the front articulation processes, are placed to the inside of these processes, the ...
Ruyangosaurus shared its habitat with Xianshanosaurus, "Huanghetitan" ruyangensis, Yunmenglong, Luoyanggia, and Zhongyuansaurus.The horizon of Ruyangosaurus was originally described as being of "early Late Cretaceous" age, [1] but recent work has assigned it an Aptian-Albian Age based on fieldwork and analysis of invertebrate and microfossil assemblages.
Yuanmousaurus is deemed to be a basal member of the Eusauropoda, standing outside the Neosauropoda, which comprises all more derived sauropods.In its species description, Lü Junchang and colleagues considered Yuanmousaurus a member of the Euhelopodidae that was closely related to Patagosaurus, more basal than Euhelopus, and more derived than Omeisaurus.
