Diagnosis
ReferenceDiagnosis
F. V. Iori et al. 2021Mid-sized (~5 m long) abelisaurid theropod with the following combination of characters not known in any other theropod (autapomorphies are marked with an asterisk): first caudal vertebra with anterolaterally projected triangular process placed below and at mid-length of the anterior edge of the transverse process*, first caudal vertebra with a notch at the anterodistal portion of the transverse process (possibly to receive the iliac blade), between a shelf-like process and the anterodistal corner of the transverse process*; first caudal vertebra with a very concave and broad anterior (=prezygapophyseal) centrodiapophyseal fossa; anterior caudal vertebrae (present in C1 and C7, inferred in the others) with a cuneiform process, anterodorsally projected, located on the dorsal surface of the transverse process, near the anterior base of the neural spine*; increased inclination (from ~20◦ to ~35◦) of the transverse processes along the first third of the vertebral caudal region*; lack of medial centrodiapophyseal fossa (=infradiapophyseal fossa) in the first caudal; presence of reduced anterior and posterior centrodiapophyseal laminae in the seventh caudal; lack of ischial tuberosity.
