“…The site-selectivity of the reworked area, which is restricted to the upper part of older laminae makes autocoprophagy, as envisaged in the cache model for Zoophycos (Bromley, 1991), very unlikely in Euflabella. A similar feeding strategy, combining deposit feeding, surface detritus feeding, and bacterial gardening has postulated for Tasselia ordamensis De Heinzelin (Olivero and López Cabrera, 2010), which is commonly associated with E. sinuosa in Tierra del Fuego (Fig. 3) and with E. multiplex in Antarctica (Fig.…”

“…However, a striking feature is the distinctive representation, in cases with absolute dominance, of trace fossils which are unknown, or poorly known, elsewhere in the world. In previous papers, we have already described some of these, including the ichnogenera Paradictyodora (Olivero et al, 2004), Patagonichnus (Olivero and López Cabrera, 2005), and Tasselia (Olivero and López Cabrera, 2010). The main objective of this paper is to describe another new group of distinctive trace fossils, which are well represented in the~2400 m thick, Campanian-Maastrichtian shelfal mudstones and fine-grained sandstones of the Marambio Group, James Ross Basin, Antarctica and the~500 m shelf deposits of the Leticia Formation, Austral Basin, Tierra del Fuego.…”

Fine-grained sandstones and siltstones of Late Cretaceous to Eocene age in Antarctica and Tierra del Fuego yield an association of well-known shallow-marine trace fossils. Among them stick out complex spreite burrows, which are formally described asEuflabellan. igen. and subdivided into five ichnospecies with different burrowing programs and occurrences. As shown by concentrations of diatoms, radiolarians, foraminifers, and calcispheres in particular backfill lamellae, the unknown trace makers lived on fresh detritus from the surface as well as the burrowed sediment. In some ichnospecies, vertical sections show that the spreite is three-dimensionally meandering in upward direction and that upper laminae tend to rework the upper backfill of the folds underneath. This could mean a second harvest, after cultivated bacteria had time to ferment refractory sediment components, which the metazoan trace maker had been unable to digest before.

Geochemical composition of faecal pellets as an indicator of deposit-feeding strategies in the trace fossilPhymatoderma

Phymatoderma is a branching burrow system consisting of tunnels filled with faecal pellets, and it has been interpreted as a product of a surface deposit‐feeding animal. Elemental analyses of Phymatoderma were conducted to reveal the specific feeding mode of its tracemaker, using samples from the Lower Jurassic epicontinental shelf deposits in the Dotternhausen section, southern Germany and from the Upper Pliocene continental slope deposits in the Shioura section, central Japan. Elemental compositions of the pelletal infill of Phymatoderma and its overlying mudstone from the Dotternhausen section show no significant difference, suggesting that the tracemaker was a non‐selective deposit feeder. In contrast, elemental compositions of the tuffaceous pellets of Phymatoderma from the Shioura section and its overlying volcanic ash show a difference in trends: CaO is significantly concentrated in the pellets. Because microfossils such as foraminifera and coccoliths are occasionally found in the tuffaceous pellets, CaO accumulation in the pelletal infill indicates the Phymatoderma‐producer that lived in the Pliocene slope setting selectively ingested particles with higher biomass of such microorganisms (or ingested microorganisms themselves) when feeding the surface sediments. Although two types of feeding modes of the tracemaker were recognized in Phymatoderma between different bathymetrical settings, each feeding mode seems to be an effective strategy to intake nutrients from the surface sediments and to reflect an adaptation of the tracemaker to the food contents in the surrounding substrate. This study suggests that geochemical composition of faecal pellets of trace fossils can be a useful indicator of grain‐selective/non‐selective deposit‐feeding strategies of ancient animals.
