Diagnosis
Reference | Diagnosis | |
---|---|---|
L. D. Xing et al. 2014 | Small- to medium-sized functionally tridactyl theropod tracks, with a hallux trace being occasionally present and with a phalangeal pad formula (including metatarsophalangeal pads II and IV) of 2-3-3-4-x and x-3-3-4-x respectively, if a hallux trace is absent. The L/W ratio ranges between 1.1 and 1.9, the divarication angles range between 44° and 70°, and the mean L/W ratio of the anterior triangle ranges between 0.70 and 0.93. An elongate and swollen metatarsophalangeal area consists of a larger metatarsophalangeal pad of digit IV and a smaller, medial metatarsophalangeal pad behind digit II, likely belonging to digit II. The proximal (metatarsophalangeal) area of the footprint is larger than any individual digital pad trace. |
