meet xingxiulong yueorum A new species of early extermination Zauropodmorph dinosaurs that lived in present-day China during the early Jurassic period.
xingxiulong yueorum It belongs to Masopoda A large group of Sauropodomorph dinosaurs described in 2007.
The new species is merely the second member of the previous monopolar genus. xingxiulong.
“xingxiulong yueorum It is distinguished from xingxiulong chengi By owning a pendant-shaped fourth trochanter with a distal end, an Astragalus with a rear almost straight dorsal margin, and a Pedalgiet V with two factors” Paleonanthropology and Chinese Academy of Sciences University, and colleagues.
Partial postcranial skeletal structure of xingxiulong yueorum It was discovered in 2015 near the city of Lufen in Yunnan Province, China.
The specimen is Lufeng Layer.
“The Rufen Formation is one of the most important sedimentary units for understanding the evolution of early Jurassic sauropod dinosaurs,” the paleontologist said.
xingxiulong yueorum Estimated to reach lengths of 8-10 m (26-33 feet) – twice the size xingxiulong chengi.
“Both of both species xingxiulong There are usually four sacral vertebrae associated with delayed sauropods and sauropods, suggesting a complex early evolution of sauropods,” the researchers said.
According to the team, the discovery xingxiulong yueorum Adds diversity of Sauropodomorph dinosaurs from the Lufeng Formation.
“This finding contributes to an understanding of the complex patterns that characterize the early evolution of Asian sauropods,” the authors concluded.
Their paper It was published in the journal on February 3, 2025 Historical Biology.
