The family lived from the upper Cambrian to middle Permian and the shells are characterized by a relatively small median sinus in the upper margin of the aperture, and collabral (transverse) or spiral (longitudinal) threads covering the shell. The shells are planispirally coiled (flat coiled) rather than trochospirally with a spire as is the case with most shelled gastropods. == Taxonomy == Knight et al. 1960, in the Treatise on Invertebrate Paleontology, Part I〔 includes the Bucanellidae in the Prosobranchia, recognizing them as true gastropods, but as the subfamily Bucanellinae within the family Sinuitidae. The current gastropod taxonomy, taxonomy of the Gastropoda by Bouchet & Rocroi, 2005〔Bouchet P. & Rocroi J.-P. (Ed.); Frýda J., Hausdorf B., Ponder W., Valdés Á. & Warén A. 2005.
