Mesoglorypteryx was an aggressive predatory dinosaur, and the prey remains found in its abdomen proved that it was a ferocious animal.
However, paleontologists also found some large but small number of gastroliths in the fossils of Sinoptera. Previously, gastroliths were only found in the fossils of herbivorous dinosaurs, which may indicate to us that carnivorous dinosaurs also had the habit of swallowing stones to aid digestion.
Zhonghuayuyulong has feathers like the Sinosaurus found in the same area. In the fossil, its head, neck, buttocks, both sides of the tail, and parts of its limbs can be clearly seen. Analysis shows that these filaments are basically the same as the skin derivatives of Sinosauropteryx, so paleontologists gave it the adjective "Liyu".
