Serpentichnus

Ichnogenus of trace fossil

Serpentichnus (‘snake-like trace’) is a possible Permian trace fossil found in New Mexico, US.[2] It takes the form of foot imprints separated by discontinuous groves interpreted as body imprints. It is attributed to early amphibians (Lysorophia) swimming near the bottom of a shallow body of water with a motion like that of a sidewinding snake.[1][3]

The interpretation of these marks as a trace fossil is controversial.[2] The marks have also been interpreted as tool marks, formed by a rotating piece of debris that periodically scratched the bottom of a flowing body of water.[4]
