Classification The authors place Shailuludia as a stem group Annelid fossil genus. They do not go further within Annelida, but regard as unlikely placements of the fossil object as other phyla or as abiotic mineral crystals [details]
Diagnosis Authors: "Diagnosis of genus and species by monotypy = Soft-bodied annelid with flattened fans of fused blade-like chaetae covering the dorsum along the midline." [details]
Etymology authors: Shaihuludia is a name taken from a modern fiction work and is modified from "Shai-Hulud: the indigenous name for the sandworms on the planet Arrakis in the Dune novels written by Frank Herbert" The authors do not explain how the '-ia' suffix modifies the noun Shaihulud. They do not state the gender of the genus, but perhaps it is neuter as sexual activity of sandworms in the novels does not seem to be part of their biology. [details]
