Résumé

Five specimens ofSphenothallus have been observed in Early Devonian slates from West Germany which have been studied bv radiographs. This genus has been assumed by several authors to be a “worm tube” or that it may belong to the Conulata. Some individuals show soft parts extending from the aperture. All preserve a bilaterally symmetrical tentacular apparatus.Sphenothallus could be related to the Annelida, but cannot be placed in that phylum since no evidence of segmentation is preserved. In specimens from other localities,Sphenothallus has been observed to have a chitinophosphatic tube, unlike the calcareous tube of living tube-dwelling annelids. What can be observed of the apertural soft parts indicates a mode of life similar to that of members of the modern-day annelid order Sabellida.
