About Limnopus
Limnopus is an ichnogenus of ancient tetrapod footprint. Its footprints have been found in Moscovian aged-rocks situated in Alveley, Shropshire, England, Colorado and West Virginia.
According to Milan et al. (2016) the diagnostic characters Limnopus are: Track-ways of a quadrupedal tetrapod with plantigrade to semiplantigrade imprints, pace angulation 80°–96°, stride : pes length = 3–5.5 : 1; pes impressed closely behind manus, pentadactyl, digits increasing in length from I–IV, digit IV longest, digit V as long as digit II and occasionally missing, short and broad oval sole, in deeply impressed imprints with proximolateral ‘heel’, robust basal pad of digit I, distal ends of digits rounded; manus tetradactyl with short broad, distally rounded digits, digits increasing in length from I–III, digit III longest, digit IV slightly shorter (80–90% of digit III), mostly longer than digit II, digit I with deeply impressed proximal pad similar to that in the pes.
