Huaiheceras

Huaiheceras is a genus of ellesmerocerd from China, and type for the Heuhiceratidae that lived during the Late Cambrian. The shell is small, tubular, gently expanding and with a slight curvature. The siphuncle, which is proportionally narrow, is on the outer, concave curvature of the shell, suggesting it is exogastric. Septa are close spaced.
