“…Notably, in the early Middle Jurassic, regional uplift of structural highs took place in northern Europe, resulting in a change from marine shelf deposition in the Early Jurassic to widespread emergence, erosion and localized deposition [97]. Besides, in some intervals of the upper Bajocian and Bathonian, signs of sedimentation pauses and/or erosion occur in a form of exhumed concretions (hiatus concretions) that were intensively bored and encrusted in conjunctional regions of Europe, and North America [98–100]. Considering the connection between North and South America [101,102] was probably severed in the late Middle Jurassic, that further indicates possible Pangea was still a landmass before Bathonian.…”

Macronaria is a clade of gigantic body-sized sauropod dinosaurs widely distributed from the Late Jurassic to the Late Cretaceous globally. However, its origin, early diversification, and dispersal are still controversial. Here, we report a new macronarian Yuzhoulong qurenensis gen. et sp. nov. excavated from the Middle Jurassic (Bathonian) Lower Shaximiao Formation. Yuzhoulong qurenensis bears a unique combination of features, such as two accessory fossae that exist on the posterior surface of dorsal diapophyses of anterior dorsal vertebrae. Results of phylogenetic analyses demonstrate it is one of the earliest-diverging macronarians. This new material represents a Middle Jurassic fossil record of macronarian sauropod worldwide and improves the understanding of the early diversity and dispersal of the Neosauropoda. This discovery further supports that sauropods achieved a more rapid and varied morphological diversity and palaeogeographical dispersal in the Middle Jurassic.
