Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| U. Nicosia and M. Loi 2003 | Medium-sized bipedal tetradactyl footprints, ectaxonic to mesaxonic, functionally tridactyl, nearly as wide as long. First digit forwardly oriented. Digits evenly splayed giving an overall fan-shaped impression. Rounded metapodial pad below digit III and IV. Second and fourth digits are sub-equal in length while the third is the longest. Relatively fleshy digits showing well developed pads. Triangular, slightly smooth, long, claw marks on all digits. Trackways variable but with quite a wide pace angulation ranging between 140° and 170°. | |
