Diagnosis
ReferenceDiagnosis
L. Xing et al. 2016Medium-sized, pes-only Caririchnium tracks with lengths almost equal to widths (1.0), quadripartite morphology including three digits with blunt claw or ungual marks, and triangular heels. Differ from other Caririchnium tracks in having weak mesaxony (0.23 and 0.28 for type). Interdigital divarication II–IV = 46°. Short steps with pace length being 2.0 x footprint length.
