Augerinoichnus (âÂÂAugerino traceâÂÂ) is a Permian trace fossil that has been found in New Mexico, US.
The trace fossil is a corkscrew-shaped burrow that, when partially eroded out at the surface, has the appearance of a set of horseshoe-shaped imprints. It takes its name from the augerino, a troublesome wormlike creature in New Mexico farming folklore that burrows into and drains irrigation ditches. The ichnogenus is unusual in being found in a tidal flat environment; most fossil burrows are characteristic of deeper water.
