A new species of asymmetrically feathered troodontid in Nature Communications.


Jianianhualong tengi  is from the Early Cretaceous of Northeastern China. It has transitional features and along with Sinusonasus provides evidence of mosaic evolution in troodontids.

The asymmetrical feathers in this taxon represent the first record in a troodontid. Taken together with other paravian feathering data, this new find suggests that the common ancestor of Paraves possessed asymmetrical feathers too.


The study is co-lead with Prof. Xu Xing of the Institute of Vertebrate Paleontology and Paleoanthropology (Chinese Academy of Sciences) and Prof. Phil Currie of the University of Alberta (Canada).
