Genus: Gordia
Emmons, 1844

Gordia is an ichnofossil known from Precambrian[1] to modern sediments 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".[2] Probably made by a worm-like creature displaying fodinichnial (sediment scavenging) behaviour.[2] 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.[2] It resembles Helminthopsis and Haplotichnus.[2]
