Monoenantiornis

single opposite bird (approximate)

• mono · Greek · single, one
• Enantiornis · Greek · opposite bird

The name appears to combine the Greek "mono" (single, one) with Enantiornis, the name of the "opposite bird" group of Cretaceous birds to which it belongs. I am not certain of the authors' exact reasoning for the name.

Period

Early Cretaceous

I believe this is a genus of enantiornithine bird (Enantiornithes) from the Early Cretaceous Jehol Biota of Liaoning, China. Birds are avian dinosaurs. I'm not fully certain of the authorship, year, formation or validity details, so I have left those fields blank. Please verify against a primary source.
