A new species from an ornithuromorph (Aves: Ornithothoraces) dominated locality of the Jehol Biota

Science Bulletin October 2014 on line first

Abstract:

We report on a new species of ornithuromorph bird, Iteravis huchzermeyeri gen. et sp. nov., from the previously unreported Sihedang locality of the Lower Cretaceous Yixian Formation, the oldest ornithuromorph bearing deposit in the world. Unlike most other Cretaceous localities, specimens from this new quarry are largely referable to Ornithuromorpha, similar to the Lower Cretaceous Aptian Xiagou Formation in Gansu Province. Also similar to the Xiagou avifauna, the fauna at Sihedang is largely dominated by a single taxon (described here). Differences in faunal dominance may suggest the Sihedang We report on a new species of ornithuromorph bird, Iteravis huchzermeyeri gen. et sp. nov., from the previously unreported Sihedang locality of the Lower Cretaceous Yixian Formation, the oldest ornithuromorph bearing deposit in the world.

Also similar to the Xiagou avifauna, the fauna at Sihedang is largely dominated by a single taxon (described here). Differences in faunal dominance may suggest the Sihedang skeleton, as well as preserves feather impressions including a rectricial morphology previously unknown among Mesozoic birds.
