Diagnosis
ReferenceDiagnosis
X. Xu et al. 2013A small parvicursorine apomorphically possessing a transversely compressed metacarpal III without a distal articular surface; also differs from all other parvicursorines in having a longitudinal ventral furrow along the entire length of each cervical centrum, diapophyseal ridges on each cervical vertebra that extend to the posterodorsal rim of the centrum, extremely weak, ridge−like epipophyses on the postzygapophyses of the middle cervical vertebrae, large pneumatic foramina in the mid−dorsal vertebrae, and anteriormost caudal vertebrae whose centra are amphiplatyan and whose neural spines are located completely posterior to the neural pedicles.
