Juehuaornis is anextinctgenus ofornithuromorphdinosaurs from theEarly Cretaceous of present-dayChina. It contains a single species,J. zhangi.[1]

Discovery and naming

[edit]

Theholotype,SJG 00001, was found nearLingyuan in a layer of theJiufotang Formation dating from theAptian. It consists of an almost complete and associated skeleton with skull, compressed on a plate. It preserves feather remains. The counterplate was designated as theparatype with inventory number SJG 00001A.[1]

In 2015 thetype speciesJuehuaornis zhangi was named and described by Wang Ren-fe, Wang Yan and Hu Dongyu. The generic name combines a reference to the island ofJuehua, the "Chrysanthemum Island" off the coast ofLiaoning, with a Greek ὄρνις,ornis, "bird". Thespecific name honours curator Zhang Dayong.[1]

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

Classification

[edit]

Juehuaornis was placed in the Ornithuromorpha in 2015.[1] In 2016 it was suggested thatJuehuaornis might be cogeneric to the closely related generaChangzuiornis andDingavis found in the same formation, in which caseJuehuaornis would have priority.[2]
