Han et al. 2014
had a tough time tracing the skull of the bird-mimic Changyuraptor (Fig. 1).
the post-cranial traits of Changyuraptor were employed to nest this bird mimic. Today a little extra effort revealed enough of the skull to make a reconstruction (Fig. 1) with gray areas added to fill out the broken, crushed and buried pieces.
Changyuraptor yangi (Han et al. 2014; Early Cretaceous) nests here between Ornitholestes and Microraptor (Fig 2) and is midway in size.
