Trace fossils constrain a trackmaker and behaviour, not a named body-fossil taxon or direct ancestry.
Eifelian bedding surfaces at Zachełmie preserve quadrupedal trackways and isolated footprints with digit impressions attributed to an unidentified limbed tetrapod trackmaker; the traces do not identify a named body taxon or direct ancestor.
