Temporal range: Tremadocian
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 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.
