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 somne of the polygonal networks of the trace fossil Paleodictyon. Such xenophyophores may be the makers of Paleodictyon, and the complex, regular geometry of Paleodictyon may be determined by the xenophyophore's anastomosing… 

Topics from this paper

Reticulammina antarctica nov. spec. (Xenophyophora, Protista) from the Weddell Sea, and aspects of the nutrition of xenophyophores
TLDR
The hypothesis is offered that nutritional nitrogen compounds adsorbed by clay minerals can be extracted by these deep-sea rhizopods.
Chapter 10 - Marine Invertebrate Neoichnology
TLDR
The burrows made by select genera in these six groups, and variations in the diversity and density of burrowing as a function of physical and chemical stresses, are presented as analogs for paleoichnological studies.
Pennsylvanian phylloid algae interpreted as shallow‐water xenophyophores
Xenophyophores, a group of agglutinated rhizopod protists, occur in nearly all the world's oceans at depths generally in excess of 1OOO m. In certain areas they dominate deep-sea, megafaunal
Paleodictyon nodosum: a living fossil on the deep-sea floor
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
Giant Paleodictyon in Eocene flysch
Abstract A giant Paleodictyon gomezi with a maximum mesh diameter of 13 cm and covering more than 0.5 m2 occurs in the lower Eocene flysch near Zumaya. The giant Paleodictyon occurs with flute casts
Quantitative ichnology of modern pelagic deposits in the abyssal Atlantic
Abstract Quantitative sedimentologic aspects of bioturbation were investigated in a series of deep-sea box cores, which were collected over a broad latitudinal range (35°N to 30°S) and bathymetric
Commentary: Paleoecology of graphoglyptids
TLDR
In terms of the Phanerozoic development of deepsea trace fossil assemblages, was the apparent enrichment of ichnotaxa (including graphoglyptid in the late Mesozoic linked to the appearance and proliferation of angiosperms; or, did changes in ocea...
Abundance and morphology of Paleodictyon nodosum, observed at the Clarion-Clipperton Zone
TLDR
In both size and morphology, the Paleodictyon traces reported were more similar to the Australian examples than to those from the Mid-Atlantic Ridge, which are better understood as reflecting the activity of an individual organism.
Palaeobiology and evolution of the earliest agglutinated Foraminifera: Platysolenites, Spirosolenites and related forms
Tubular agglutinated fossils of Platysolenites antiquissimus Eichwald, 1860, P. cooperi n.sp. and Spirosolenites spiralis Glaessner, 1979 are examined from selected lower Cambrian successions in
Giant, highly diverse protists in the abyssal Pacific: vulnerability to impacts from seabed mining and potential for recovery
TLDR
Xenophyophores, giant deep-sea agglutinated foraminifera, dominate the benthic megafauna in the eastern equatorial Pacific Clarion-Clipperton Zone and could be among the first large immobile organisms to reappear in mining-impacted areas.
