Fun Facts about Huaxiagnathus

Huaxiagnathus was a small, agile carnivore. It was a member of the Compsognathid family, and a pretty large member of that family, roughly half a metre longer than Compsognathus, which it also resembled.

Huaxiagnathus had nearly identical bone structure to Compsognathus and Sinosauropteryx, but its forelimbs were proportionally larger and more developed, implying a higher involvement in prey acquisition and feeding. The holotype is a nearly complete, well-preserved skeleton, with only the last sections of the tail lacking.

The fossils of Huaxiagnathus indicate that the dinosaur genus was the most primitive compsognathid genus. In regards to the premaxilla, however, they were distinct from other compsognathids. The teeth of these dinosaurs indicate that they were carnivores. It is likely that the Huaxiagnathus had feathers.
