Paleodictyon also preserves vertically ascending tubules that have been likened to those of Occultammina. However, this relationship has been contested. The large size (up to 0.5 m (1 ft 8 in)) of some Paleodictyon is unknown in modern Occultammina; the regular hexagonal pattern of Paleodictyon is similarly not represented in Occultammina. The ...

Paleodictyon Meneghini, 1850 1 is a well-known trace fossil belonging to the graphoplyptid group, characterized as a “three-dimensional burrow system consisting of horizontal net composed of regular to irregular hexagonal meshes and vertical outlets. Preferentially the net is preserved” 2 (emended diagnosis by Uchman 3).Regular nets of …Two specimens, and a possible third, of the ichnotaxon Paleodictyon are documented from shallow-water marine strata of the Upper Ordovician Georgian Bay Formation of southern Ontario. Its occurrence indicates that previous suggestions of a post-Early Cambrian palaeoenvironmental retreat of Paleodictyon into deeper water require some modification.
