Hamipes didactylus Hitchcock, 1858

Emended Diagnosis. A trackway consisting of two rows of elongate, crescentic or j-shaped imprints arranged into series with staggered to alternating symmetry. Tracks approximately par-allel to each other and to the trackway midline. The outer track is longer than the inner track. Inner and outer tracks are closely spaced and the negative space between the track rows accounts for 80 – 90% of the trackway width.
