Occasionally, we should pause to re-review worthwhile contributions to the scientific literature that deal with Bigfoot and Sasquatch. In 2007, Jeff Meldrum, Ph. D., published one such paper. It was entitled “Ichnotaxonomy of Giant Hominid Tracks in North America,” and dealt with his understanding of the patterns being seen among Sasquatch and Bigfoot tracks, prints, and to a lesser extent, trackways.

Abstract—Large bipedal hominoid footprints, commonly attributed to Bigfoot or sasquatch, continue to be discovered and documented, occasionally in correlation with eyewitness sightings, and rarely in concert with photographic record of the trackmaker (gen. et sp. indet.). One of the best-documented instances occurred in 1967, when Roger Patterson and Bob Gimlin filmed an over two meter tall upright striding hominoid figure, at the site of Bluff Creek, in Del Norte County, California, and cast a right and left pair of exceptionally clear footprints in firm moist sand. Additional footprints were filmed, photographed, and cast by multiple witnesses. Molds and casts of a series of these are reposited at the National Museum of Natural History, Smithsonian Institution, while ten original casts are among the Titmus Collection at the Willow Creek – China Flats Museum, Humboldt County, California. These casts have been 3D-scanned and archived as part of a footprint virtualization project and scan images are accessible on-line through the Idaho Museum of Natural History. The initial pair, originally cast by Patterson, and the remaining casts made by Titmus, are designated the holotype of a novel ichnogenus and ichnospecies describing these plantigrade pentadactyl bipedal primate footprints – Anthropoidipes ameriborealis (“North American ape foot”). The footprints imply a primitively flat, flexible foot lacking a stiff longitudinal arch, combined with a derived, non-divergent medial digit.
