摘要	The recently described maniraptoran theropod Zhongornis haoae, known from a single juvenile specimen, was originally identifi ed as a bird. However, morphological re-evaluation reveals striking resemblances to both Oviraptorosauria and Scansoriopterygidae. The reduced, but still long, boney tail is reinterpreted as having approximately twenty vertebrae and is reminiscent of the tails of Caudipteryx and Epidexipteryx in its proportions and morphology. Other morphological similarities with basal oviraptorosaurs include a short and deep skull, and a reduced minor digit. Zhongornis also differs strikingly from other Mesozoic birds, and resembles scansoriopterygids, in the size of the alular metacarpal, the proportions of the manual digits, and the lack of processes on the ischium. These similarities, together with resemblances between basal oviraptorosaurs and previously described scansoriopterygids, may point to a close relationship between these two clades. Cladistic analysis confirms a close relationship between Zhongornis and Scansoriopterygidae, which share forelimbs and pedal unguals that are elongate compared to those of oviraptorosaurs, but does not support oviraptorosaur affi nities for this clade. Additional specimens will be required in order to determine both the taxonomic placement of this species and the affi nities of Scansoriopterygidae, highlighting the drawbacks of basing new species on juvenile material.
