Extinct genus of molluscs
Paradakeoceras is a genus of early Ordovician cephalopods belonging to the nautiloid order Ellesmerocerida.
Morphology.
The shell of "Paradakeoceras" is an expanding endogastric cyrtocone with the siphuncle situated near the shell's concave margin. 
A raised ring exists at the base of the body chamber, which is often preserved as a mould.
"Paradakeoceras" was named by Flower, 1964, for species previously included in "Dakeoceras" in which the cross section is broadened with consequent loss of lateral lobes in the suture.
"Paradakeoceras" shows a flattening of the venter which distinguishes it from "Quebecoceras" and has a reduction in the rate of expansion similar to that of "Dakeoceras".
