“…Another approach for estimating the possible trackmaker is integrating osteological gures obtained from trace fossils with pterosaurian body fossil records in the vicinity. Nevertheless, the pterosaur body fossil records in the Korean Peninsula are very rare, including partially preserved wing nger phalanxes and isolated teeth of borepteridae in the Hasandong Formation (Aptian) [58][59][60][61] , with represents a geological time gap from the Hwasun Seoyuri tracksite. Despite expending the scope to the Upper Cretaceous strata of East Asia, the pterosaur fossil records are not su cient to be a candidate for Pterichnus isp.…”

The pterosaur is the earliest and largest powered flying vertebrate, even earlier and larger than the other extant archosaurian group, birds. However, evidence for this flying reptile, including the diversity of the small-sized pterosaur after the mid-Cretaceous, and their ecology, has remained elusive. Here we present numerous and dense pterosaur track assemblages from the Hwasun Seoyuri tracksite in the Upper Cretaceous Jangdong Formation of the Neungju Basin in Korea. The pterosaur track assemblage, assigned to Pteraichnus isp., consists of various sized, randomly oriented manus-dominated tracks with several pes claw marks. These features commonly indicate the semi-aquatic behavior and multi-age gregariousness of pterosaurs. The supposed trackmaker of pterosaur tracks would be the small-sized pterodactyloid that inhibited the Late Cretaceous Korean Peninsula, but that has not previously been reported. This ichnological evidence for the global distribution of small-sized pterosaurs could be interpreted to mean that the pterosaur fauna in the Late Cretaceous was more distributed and diverse than was previously known.
