lifestyle rather than a juvenile feature and the presence of open neural arch-central sutures in vertebrae cannot be used to indicate the juvenile nature of the type specimen as it is a feature also documented in young adult eosauropterygians. In addition to a semiaquatic lifestyle, the authors suggested that Liaoningosaurus was carnivorous based on the elongated and fork-like denticles of the crowns of the cheek teeth, sharp unguals on the hands and feet, and the presence of fish within the skeleton of the second specimen. They proposed three explanations as to how this association may have occurred, with the first explanation being that the fish, lying at the bottom of a lake or river, passively went into the ribcage due to underwater turbulence. The second explanation suggests that the fish died whilst within the ribcage when they were scavenging, while the third explanation is that the fish represent gut contents. The authors considered the third explanation to be the most reasonable, arguing that the obscure body outline and incompleteness of the fish being was caused by digestive acids. The fish skeletons are scattered on both sides of the body cavity instead of being tightly packed in the stomach region, which may have been caused by the expulsion of gases or the compression of the stomach region post-mortem. In addition to fish, the tail of a lizard is preserved on the posterolateral side of the ribcage. Paleontologist Andrea Cau has expressed skepticism on the idea, considering it too radical in view of the actual evidence, which could be explained by more parsimonious interpretations: reduced ossification of the skeleton and small size are typical traits of juveniles, and abundance of juvenile individuals compared to the adults is coherent of what is known of Mesozoic dinosaurs population dynamics and of high conservation deposits. Also, the aquatic depositional setting in which the specimen was found doesn't necessarily mean the animal itself was aquatic (many other dinosaurs have been found in such contexts) and the chaotic distribution of fish inside the thoracic cavity, and the presence of one outside of it, are more coherent of fish scavenging on the animal's carcass (it would also be expected that, given the abundance of specimens, more showed evidence of a supposedly piscivorous diet, but such is not the case). Ontogeny Arbour and Currie (2015) considered the type specimen to represent a juvenile individual on basis of unfused neural
