Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| A. Cau et al. 2017 | Long-necked dromaeosaurids with proximal caudal vertebrae that have horizontally oriented zygapophyses and prominent zygodiapophyseal laminae; flattened ulna with a sharp posterior margin; metacarpal III shaft transversely as thick as that of metacarpal II; ilium with a shelf-like supratrochanteric process; posterodistal surface of femoral shaft with an elongate fossa bound by a lateral crest; proximal half of metatarsal III unconstricted and markedly convex anteriorly. | |
| A. Cau and D. Madzia 2018 | The clade Halszkaraptorinae is diagnosed by the fusion of the cervical ribs to centra (unknown in Hulsanpes); presence of a distinct prezygocostal lamina in proximal caudal vertebrae (unknown in Hulsanpes); horizontal orientation of the zygapophyseal facets in the proximal caudal vertebrae (unknown in Hulsanpes); abrupt reduction in size of the proximalmost caudal neural spines (unknown in Hulsanpes); presence of a prominent supratrochanteric process on ilium that is curved dorsolaterally (unknown in Hulsanpes); presence of a marked lateral ridge along the posterior margin of the distal end of the femur (unknown in Hulsanpes); unconstricted proximal end in metatarsal III (present in Hulsanpes); presence of a transversely convex dorsal surface of metatarsal III (present in Hulsanpes). | |
| S. Lee et al. 2022 | Small dromaeosaurids that possess dorsoventrally flattened premaxillae, premaxillary bodies perforated by many neurovascular foramina, enlarged and closely packed premaxillary teeth that utilized delayed replacement patterns, reduced anterior maxillary teeth, dorsolateral placement of retracted external nares, greatly elongated cervical vertebrae, anterior cervical vertebrae with round lobes formed by the postzygapophyses, horizontal zygapophyses, and pronounced zygapophyseal laminae in the anterior caudal vertebrae, mediolaterally compressed ulnae with sharp posterior margins, second and third metacarpals with similar thicknesses, shelf-like supratrochanteric processes on the ilia, elongated fossae that border posterolateral ridges on the posterodistal surfaces of the femoral shafts, and third metatarsals in which the proximal halves are unconstricted and anteriorly convex. |
