Holocene lingulid brachiopods are well‐known burrowing organisms. Fossil lingulid burrows have been reported from rocks in Europe and North America that range from Ordovician and Devonian through Pennsylvanian. However, the latest authoritative compendium on trace fossils, The Treatise on Invertebrate Paleontology (1975). makes no mention of lingulid burrows. The obvious reason for this omission is that the burrows, although important paleontologically and ichnologically, have never been named formally thereby making it awkward to include them in faunal lists. The monotypic genus Lingulichnites is proposed to remedy this problem. The type specimens are from Upper Devonian rocks in northeastern Ohio.
