Paleodictyon is a fossil found in sedimentary rocks that once formed the deep seabed. It consists of a network of tunnels or tubes that would have sat a few millimetres underground, with vertical shafts leading up to surface. Palaeontologists traditionally interpret it as a burrow system, dug by an unknown maker. ...These conditions are probably linked to distal depositional areas, characterized by the record of the Paleodictyon ichnosubfacies in interbedded sandstones-mudstones, with a common occurrence of Tab/Tabc Bouma intervals.

Modern Paleodictyon traces resembling these were first photographed on the seabed at the Mid-AtlanticRidge(MAR)byRonaandMerrill(1978)andhave been assigned to the Eocene species Paleodictyon nodosum (Seilacher 1977;Ekdale1980;Ronaetal.2009).Boththefossil and modern forms are known only from deep-sea sediments, Paleodictyon is a pattern, usually interpreted to be a burrow, which appears in the geologic record beginning in the Cambrian and in modern ocean environments. [1] [2] [3] Both irregular and regular nets are known throughout the stratigraphic range of Paleodictyon , but it is the striking regular honeycomb pattern of some forms such as P ... It's not Paleodictyon as it is a body fossil, not a trace fossil. It's also likely not a scleractinian coral as the septa in the habit appear to have bilateral symmetry (dominated by a single set) instead of radial symmetry. So I would say this is a colonial rugose coral. Steve_Hufnagel • 5 mo. ago. Thank you!

Paleodictyon nodosum is a living creature thought to produce a certain form of burrow nearly identical to Paleodictyon fossils.
