QUOTE `{}`	Lower Cretaceous Jiufotang Formation at Changzigou locality, Sanjiazi Town of Lingyuan City, Liaoning, China, dated to approximately 120 million years ago. Skeleton lacking left humerus, ulna, and radius. IMMNH-PV01700.
QUOTE `{}`	Given that the first incisor has a replacement tooth, that replacement represents a third generation (i.e., polyphyodonty).
QUOTE `{}`	Our results show that Dongoconodon falls within the locomotor morphospace formed by the nine semiaquatic species, with a 100% posterior probability supporting a semiaquatic locomotor mode.
QUOTE `{}`	The final dataset comprised 13 functional indices across 124 extant species.
