Diagnosis
ReferenceDiagnosis
M. G. Lockley et al. 2006Trackway of a large biped; digitigrade; four straight, anteriorly oriented digit impressions; clear basal pad, related to the presence of an ubiquitous fifth digit on the posterolateral margin; digits almost completely separate along their lengths; foot axis orientation slightly variable from inward to outward.
S. D'Orazi Porchetti and U. Nicosia 2007Trackway of a biped of large dimension, digitigrade. Four straight digits impressions anteriorly oriented. A clear basal pad, related to the presence of a fifth digit always present on the rear margin, slightly on the external border. Digits almost completely separated along their length. Foot axis orientation slightly variable from inward to outward.
