Diagnosis
ReferenceDiagnosis
R. D. Martínez and F. E. Novas 2006Small theropod with the following autapomorphies: cervical vertebrae with the neural arch pedicels unusually deep (i.e., 2.5 times the height of the centrum); wide neural canal on cervical vertebrae; cranial caudals with ventral saggital keel; manual ungual phalanges robust; iliac brevis shelf lateroventrally expanded; caudolateral surface of proximal femur with strong depression and rugosities presumably for the attachment for M. ischiotrochantericus; metatarsal IV and its correspondent digit transversely narrow.
