The pattern looked to Seilacher like surface features he had modeled for an ancient creature known only by its tunneling trace fossil: Paleodictyon nodosum. That s pecies left a meshwork of tunnels in the deep-sea turbidities of the Eocene and is part of a group of similar trace fossils that date back to shallow, marine deposits from the Cambrian.Morphological analysis of Paleodictyon was based first on visual observation in order to differentiate morphotypes with an inner hexagonal pattern (Paleodictyon Morphotype 1; PM1) from those with ...

Scattered records of the trace fossil from shallower, lower-shelf-to-upper-slope environments, particularly since the mid-Mesozoic, have been substantially augmented by new data from Upper ...Ejemplar: Paleodictyon isp Descripción: Túneles que forman redes hexagonales regulares tipo panal, generalmente registrados en ambientes de poca energía y grandes profundidades. Aparecen desde el Precámbrico hasta el Eoceno aunque fueron localizadas estructuras actuales en 1976 en el fondo del Atlántico. Conservadas en areniscas de grano grueso como epirrelieve convexo.
