Ichniotherium
''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.Buchwitz M & Voigt S. (2018On the morphological variability of Ichniotherium tracks and evolution of locomotion in the sistergroup of amniotes PeerJ 6:e4346 https://doi.org/10.7717/peerj.4346 These footprints are commonly found in Europe, and have also been identified in North America and Morocco. Three ichnospecies of ''Ichniotherium'' have been proposed as valid: ''I. cotta'', ''I. sphaerodactylum'', and ''I. praesidentis.'' 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 Germany,, officially the Federal Republic of Germ ...

Orobates
''Orobates'' is an extinct genus of diadectid reptiliomorphs that lived during the Early Permian. Its fossilised remains were found in Germany. A combination of primitive and derived traits (i.e. autapomorphic and plesiomorphic) distinguish it from all other well-known members of Diadectidae, a family of herbivorous reptiliomorphs. It weighed about 4 kg and appears to have been part of an upland fauna, browsing on high fibre plants. Locomotion The trace fossil species ''Ichniotherium sphaerodactylum'', from Bromacker in Germany, has been attributed to ''Orobates''. A study in 2015 found that the genus was characterized by a long body and tail, with fairly short legs and a short skull compared to the more derived ''Diadectes''. This indicates ''Orobates'' was less specialised for long treks compared to ''Diadectes''. A three-dimensional digital reconstruction of the holotype specimen allowed further analysis of the postcranium. An analysis of the mobility of the hip joi ...
