Diagnosis
Reference | Diagnosis | |
---|---|---|
L.-d. Xing et al. 2009 | Small, didactyl theropod track that lacks manus and tail traces. The digit III:digit IV length ratio of T.A.1 is 2.36 (average value of T.A.1–4 is 1.8), differentiating the ichnotaxon from Velociraptorichnus, Dromaeopodus, and Dromaeosauripus, in which digit IV is almost as long as digit III. Digit II, when present, is represented only by a short, round impression located at the proximomedial margin of digit III. The divarication angle between digits III and IV ranges from 40°-44°, wider than in Velociraptorichnus, Dromaeopodus, or Dromaeosauripus |
