''Conostrichoceras'' is a genus belonging to the [[Nothoceratidae]] (Oncocerida) from the Middle and Upper Devonian. The shell is a moderately depressed, rapidly expanding exogastric cyrtocone. Septa are straight and close-spaced. Lateral profiles are moderately convex, producing a slightly bulged appearance. The siphuncle is ventral, composed of adapically expanded and adorally narrowed segments.

''Conostrichoceras'' differs from ''[[Blakeoceras]]'' from which it is apparently derived by its convex lateral profile, and from the also closely related ''[[Turnoceras]]'' in having a less strongly curved phragmocone, and from both by the details of the siphuncle.
