ABSTRACT Stegosaurs are a major clade of ornithischian dinosaurs, yet because of their fragmentary fossil record, their interrelationships and early evolution are poorly understood. Here, we describe a new stegosaur, Bashanosaurus primitivus, gen. et sp. nov., and some other indeterminate stegosaur materials. We provide new U-Pb detrital zircon ages for horizons bounding the holotypic quarry in the Lower Member of the Shaximiao Formation, Yunyang, Chongqing Municipality, China, which indicate a…

A new possible megalosauroid theropod from the Middle Jurassic Xintiangou Formation of Chongqing, People’s Republic of China and its implication for early tetanuran evolution

Yunyangosaurus presents a combination of derived and apparently primitive character states that are not seen in other theropods, suggesting that patterns of morphological evolution associated with deep tetanuran divergences were more complex than currently recognized, with implications for understanding the character evolution in theropod.

A new species of Omeisaurus (Dinosauria: Sauropoda) from the Middle Jurassic of Yunyang, Chongqing, China

Comparative study and cladistic analysis show that this new taxon belongs to Omeisaurus, and bears a unique combination of character states, such as all presacral vertebrae opisthocoelous, complex pneumatic fossa system in middle cervical centra.

The Postcranial Skeleton of an Exceptionally Complete Individual of the Plated Dinosaur Stegosaurus stenops (Dinosauria: Thyreophora) from the Upper Jurassic Morrison Formation of Wyoming, U.S.A.

Several aspects of its morphology indicate the individual was not fully skeletally mature at the time of death, corroborating a previous histological study and enabling additional comparisons with other stegosaurian dinosaurs.

RE-DESCRIPTION OF THE POSTCRANIAL SKELETON OF THE MIDDLE JURASSIC STEGOSAUR HUAYANGOSAURUS TAIBAII

The plesiomorphic status of Huayangosaurus suggests that substantial convergence between ankylosaurs and stegosaurs occurred during their respective evolutionary histories, reflecting coincident functional morphological changes associated with the adoption of obligate quadrupedality.
