What is "bohaiornis"

Bohaiornis is a genus of enantiornithine birds. Fossils have been found from the Lower Cretaceous Jiufotang Formation of western Liaoning, China. The only known species, Bohaiornis guoi, was named by Dongyu Hu, Li Li, Lianhaim Hou and Xing Xu in 2011 on the basis of a fully articulated and well-preserved skeleton of a sub-adult. It was similar to the earlier Eoenantiornis, but much larger in size. A second, even larger specimen was reported in 2014. This second specimen showed that the snout was relatively broad compared to other enantiornithes, and also preserved a few large gastroliths in the stomach. The presence of few, large-sized stomach stones in birds and in other non-avian dinosaurs usually indicates a mainly carnivorous diet, suggesting that B. guoi may have had a raptorial ecology.
