Bellulia rectusunguis
Taxonomy
Bellulia rectusunguis was named by Wang et al. (2016) [A large basal ornithuromorph bird that can be distinguished from other ornithuromorphs by the unique combination of the following features: V‐shaped furcula with a short hypocleidium; sternum bearing elongated lateral trabecula with fan‐shaped distal expansion; broad cranial margin of sternum with obtuse angle defined by coracoidal sulci of 113°; manual claws nearly straight; proximal ends of metatarsals II–IV coplanar; metatarsal IV robust (autapomorphy); hallucal ungual reduced; and intermebral index (humerus + ulna + carpometacarpus/femur + tibiotarsus + tarsometatarsus) of 1.21.]. Its type specimen is IVPP V17970, a skeleton (a nearly complete and articulated skeleton with an aggregate of gastroliths in the abdominal region and feather traces preserved in a single slab, missing the s), and it is a 3D body fossil. Its type locality is Lamadong, Jianchang, which is in an Aptian lacustrine sandstone/mudstone in the Jiufotang Formation of China.
