Diagnosis
ReferenceDiagnosis
L.-D. Xing et al. 2015Small-sized (∼10.4 cm long and ∼9.4 cm wide) tridactyl theropod tracks with extremely low mesaxony. Digit II trace very narrow compared with other digits, approximately half the width of digit III; sharp claw impressions; large semicircular metatarsophalangeal region. The divarication angle between digits II and IV is 52°. The divarication angle between digits II and III is approximately half of that between digits III and IV.
