Emmons, 1844

Gordia marina is a lower Cambrian ichnofossil, and is the most common trace fossil in the Kaili biota displaying "smooth, cylindrical or subcylindrical, non-branching, winding and irregularly curving burrows, commonly self-overcrossing".[1] Probably made by a worm-like creature displaying fodinichnial (sediment scavenging) behaviour.[1] It takes the form of unlined, curving parallel-walled burrows that often end with a nub, probably created as the creature probed the over- or under-lying sediment.[1] It resembles Helminthopsis and Haplotichnus[1]
