Diagnosis
ReferenceDiagnosis
H. Klein and S. G. Lucas 2021Transverse tridactyl tracks only two thirds as long as wide, hence more transverse than typical Anomoepus with digit traces little connected, and digit divarication wide but variable. Step short, trackway very wide, with low pace angulation, and outward rotation of pes. Eoanomoepus differs from Anomoepus in length/width ratio (0.60-0.70 vs. ~1.08) and lack of obvious inward rotation characteristic of the latter, well-known ichnogenus. The trackway width of Eoanomoepus differs from Anomoepus in being unusually wide, also with usually an irregular step and stride dimensions. Eoanomoepus also differs from Anomoepus in lacking evidence of a hallux (digit I) trace and being more digitigrade.
