Description
Finished field guide entry for C. dongi. The pose is based on the first Caudipteryx I ever tried my hand at back in 2000. I'd post the link but it seems to be lost to the bowels of the internet.

As I mention in the scrapbook version, C. dongi appears to not only have secondaries, unlike the type species, but the wings are proportionally much larger, despite it being smaller in overall body size. This is the reverse of the ontogenetic pattern seen in Similicaudipteryx, so it's possible C. dongi and C. zoui are in fact distinct species (most studies have treated them as conspecific, and Mickey Mortimer in particular has argued the skeletal differences are not enough for separation).

Research: [link] and feather proportions after the photographs in
* Zhou, Z., and Wang, X. (2000). "A new species of Caudipteryx from the Yixian Formation of Liaoning, northeast China." Vertebrata Palasiatica, 38(2): 113–130.
