It is commonly called the "'sinistral spiral tubeworm "'and is the type species of the genus " Spirorbis ".

A detailed study by Taylor and Vinn ( 2006 ) of the microstructure of fossils which have been traditionally identified as " " Spirorbis " " in the geological literature revealed that they consist of the remains of at least two completely different animals.

Taylor and Vinn discovered that the " " Spirorbis " " fossils found in sedimentary strata, including the Joggins and other Carboniferous coal measures deposited from the Ordovician to Triassic periods are the remains of an extinct order of lophophorates ( now called microconchids ) unrelated to modern marine tube-worms ( Annelids ) to which the genus " Spirorbis " belongs.

This contradicts arguments made by Harold Coffin and other creationists that " " Spirorbis " " fossils within strata containing polystrate fossils indicate their deposition in a marine environment, because these fossils are classified as the remains of extinct fresh and brackish water microconchids instead of the remains of the marine genera " Spirorbis " as they have been misidentified in the geologic literature.
