A giant Paleodictyon gomezi with a maximum mesh diameter of 13 cm and covering more than 0.5 m 2 occurs in the lower Eocene flysch near Zumaya. The giant Paleodictyon occurs with flute casts and, therefore, must have been produced deeply in the sediment. The lengthening of mesh cells parallel and perpendicular to the flute casts implies ...Paleodictyon (Meneghini, 1850) DESCRIPTION: Thin tunnels and shafts forming a hexagonal- to polygonal-shaped honeycomb-like network of ridges or furrows. …The Paleodictyon pictures below show turbidite sandstone soles from the Buzău Valley; I haven't been there for a while but I hear that many of the outcrops are covered now. The first weird thing about graphoglyptids is that they developed high diversity in an environment with limited amounts of low-quality food (lack of sunlight, hence no ...

Description. Paleodictyon consist of thin tunnels or ridges that usually form hexagonal or polygonal-shaped honeycomb-like network. 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. carpathecum and P. nodosum which make it notable and widely studied. Additional material of Paleodictyon from the Guadalupian (Middle Permian) Mungadan Sandstone (Kennedy Group) of the Carnarvon Basin, Western Australia, is documented here. The Mungadan Sandstone was deposited in a nearshore depositional setting as evidenced by the lithofacies, ichnofacies and fossil assemblage.We report new in situ observations and laboratory studies of specimens of a small (diameter 2.4-7.5 cm) strikingly hexagonal form originally described from sedimented steps in a wall of the axial valley of the Mid-Atlantic Ridge (water depth 3430-3575 m) near 261N, 451W that appears to be identical to the iconic form Paleodictyon nodosum described as a trace fossil from Eocene flysch deposits ...Paleodictyon is an important trace fossilcharacterised by a regular hexagonal structure and typical of ancient deep-ocean habitats as far back as the Ordovician.

Paleodictyon is a typical graphoglyptid (Fuchs, 1895, Seilacher, 1977) that is common in thin- to medium-bedded turbiditic sediments (e.g., Uchman, 2007b, Uchman, 2007c). Paleodictyon strozzii Meneghini in Savi and Meneghini (1850) (Fig. 9 C, E) is a regular net composed of polygonal to hexagonal meshes 3-4 mm wide.A xenophyophore found just below the surface of a box core of modern deep-sea sediment from the Japan Trench has a threadlike plasma body that extends through horizontal, anastomosing networks of organically bound sediment tubes (the organism's test). The tubes resemble some of the polygonal networks of the trace fossil Paleodictyon. ….
