Tannuella is a genus of helcionellids known from Lower Cambrian strata.
It has a high, septate shell similar to that of Knightoconus . These genera were once considered ancestral cephalopods, [1] but are more broadly assigned to the helcionellids (or putatively the tergomyans); i.e. "Cambrian monoplacophora". [2]
