Ichniotherium (meaning "marking creature") is an ichnogenus of tetrapod footprints from between the Late Carboniferous period to the Early Permian period attributed to diadectomorph track-makers.[1][2] These footprints are commonly found in Europe, and have also been identified in North America and Morocco.[3][1] Three ichnospecies of Ichniotherium have been proposed as valid: I. cotta, I. sphaerodactylum, and I. praesidentis.[1]

In a 2007 study, the diadectid species Diadectes absitus was determined to be the track-maker associated with I. cotta tracks, and the related diadectid species Orobates pabsti was linked to I. praesidentis based on analysis of Lower Permian trackways and fossils skeletons in Germany[4][5]
