The shell of ''Domatoceras'' is evolute, coiled with whorls touching but not overlapping, some growing to be moderately large. Whorl section subquadrate, higher than wide. Sides essentially straight to slightly bowed and slightly convergent on a broad slightly arched venter on the outer rim. Shoulder are narrow but rounded. Chambers are short but lengthen slightly before the mature living chamber, septa close spaced, sutures form broad shallow lateral and ventral lobes and sharp ventro-lateral saddles. The dorsum in slightly impressed (indented) where it rides over the previous whorl. The siphuncle The siphuncle is a strand of tissue passing longitudinally through the shell of a cephalopod mollusk.

Arthur K
Arthur is a common male given name of Brythonic origin. Its popularity derives from it being the name of the legendary hero King Arthur. The etymology is disputed. It may derive from the Celtic ''Artos'' meaning “Bear”. Another theory, more widely believed, is that the name is derived from the Roman clan '' Artorius'' who lived in Roman Britain for centuries. A common spelling variant used in many Slavic, Romance, and Germanic languages is Artur. In Spanish and Italian it is Arturo. Etymology The earliest datable attestation of the name Arthur is in the early 9th century Welsh-Latin text ''Historia Brittonum'', where it refers to a circa 5th to 6th-century Briton general who fought against the invading Saxons, and who later gave rise to the famous King Arthur of medieval legend and literature. A possible earlier mention of the same man is to be found in the epic Welsh poem ''Y Gododdin'' by Aneirin, which some scholars assign to the late 6th century, though this is still a mat ...
