#Cratonavis zhui, a #NewSpecies of #birds from the Early #Cretaceous #JeholBiota, had a unique combination of a dinosaurian skull with an avian post-cranial skeleton, revealing the key role of evolutionary mosaicism in early bird diversification. On the bird evolutionary tree, it sits between members of the bird clade #Ornithothoraces and the more reptile-like #Archaeopteryx.
