Spirorhaphe (sometimes misspelt Spiroraphe) is an ichnogenus of spiraling burrows.[1] It is associated with the Nereitesichnofacies, which is interpreted as an indicator of deep-sea, pelagic, turbidity current-dominated systems. It is one of the most common graphoglyptid traces found in modern ocean beds.[2]
