'''Nothoceratidae''' conprise Silurian - Upper Devonian [[Oncocerida|oncocerids]] of various form, mostly all with contracted or visored apertures and venrtral siphuncles with concave segments that contain actinosiphonate depostis..  Shells include endogastric and exogasric brevicones, planispiral nautilicones, and trochoidal torticones. Derivation is from the [[Oncoceratidae]], probably from ''[[Oonoceras]]'' through ''[[Perimecoceras]]''. No descendant group is known.
