Discovery and naming

The holotype, SJG 00001, was found near Lingyuan in a layer of the Jiufotang Formation dating from the Aptian. It consists of an almost complete and associated skeleton with skull, compressed on a plate. It preserves feather remains. The counterplate was designated as the paratype with inventory number SJG 00001A.^[1]

In 2015 the type species Juehuaornis zhangi was named and described by Wang Ren-fe, Wang Yan and Hu Dongyu. The generic name combines a reference to the island of Juehua, the "Chrysanthemum Island" off the coast of Liaoning, with a Greek ὄρνις, ornis, "bird". The specific name honours curator Zhang Dayong.^[1]

Description

Juehuaornis has a long beak which reaches 70% of the total skull length.^[1]

Classification

Juehuaornis was placed in the Ornithuromorpha in 2015.^[1] In 2016 it was suggested that Juehuaornis might be cogeneric to the closely related genera Changzuiornis and Dingavis found in the same formation, in which case Juehuaornis would have priority.^[2]
