A fossil footprint or track made by an amphibian, preserved in ancient sediment or rock.
Combines Greek 'amphibi-' (amphibian) with 'ichnite' from Greek 'ichnos' (footprint, trace), used in paleontology to describe preserved tracks of ancient creatures.
Amphibichnites are time-capsules that paleontologists use to understand how ancient creatures moved—some 300-million-year-old trackways show the exact moment amphibians were learning to walk on land, revealing the transition from fish to tetrapods.
