Linoproductoidea is an extinct superfamily of brachiopods which lived from the Devonian to Permian periods.

Their fossils have been found in marine formations dating to those periods on all continents.

[1][2] Linoproductoids commonly had long but simple trails, and fine, regular ribbing across the entire shell.

Thick and symmetrical ventral spines were present on the hinge and diverse across the remainder of the valve, while the dorsal valve lacked spines (except in grandaurispinins and certain gigantoproductins).

[2] Initially, the surface of the ventral valves of linoproductoids had posterior and anterior spines of around the same thickness.
