Member feedback about List of Asian dinosaurs: It contains a single species, L. Journal of Nanjing University Natural Sciences 38 6: The specific name is the Chinese ju ji, “big crest”, in reference to the large crest on the lacrimal bone In all examples, the evidence described consists of feather impressions, except those genera inferred to have had feathers based on skeletal or chemical evidence, such as the presence of quill knobs the anchor points for wing feathers on the forelimb or a pygostyle the fused vertebrae at the tail tip which often supports large feathers.

The discovery of Jianianhualong supports the notion that asymmetrical feathers appeared early in the evolutionary history of the Paraves.

This view began to shift during the so-called dinosaur renaissance in scientific research in the late s, and by the mids significant evidence had emerged that dinosaurs were much more closely related to birds, which descended directly from the theropod group of dinosaurs[1] and are themselves a subgroup within the Dinosauria.
