The intermediate tier (C) contains randomly distributed Thalassinoides and Alcyonidiopsis, cross-cut by Zoophycos and large and medium-sized Chondrites. The deepest tier (D) contains Zoophycos, cross-cut by medium- and mainly small-sized Chondrites. Two interpretations are proposed: (1) vertical partitioning of a singled multi-tiered community ...Many previous studies have documented carbonate hydrocarbon reservoirs and aquifers with Thalassinoides. Although the linkages among burrow intensity, burrow connectivity, and reservoir quality in these reservoirs have been evaluated recently, how burrow intensity of a complex network of Thalassinoides is reflected on their two-dimensional (2D) views is less constrained.Abstract—Burrows of Thalassinoides, which are attributed to the group of dwelling structures, occur in all the marine and coastal facies.

Thalassinoides constitutes the only recorded trace fossil of the lower part of the section, in both, the mixed massif and nodular limestone and the subunit 1 of the marlstone-bioturbated limestone, attributed to the lower to middle Berriasian. It co-occurs with Zoophycos in the upper part of the marlstone-bioturbated limestone, and with …
Feb 1, 2023 · Subsurface reservoirs with Thalassinoides are well known. Using a CT scan of an 18.5 cm-diameter core (top cross section, 267.21 cm 2; length, 26.5 cm) with Thalassinoides, this study demonstrates the scale dependence of sampling, and variables important in selecting representative sample dimensions for modeling these reservoirs. In the Lower Miocene successions, few occurrences of Thalassinoides have been reported in some rock units, including the Nukhul Formation in the Gulf of Suez (Mandic and Piller, 2001;Malpas et al ...Thalassinoides, who described it from Miocene sands of Austria, considered the latter as representing Decapoda burrows. Subsequently, Ehrenberg (1944) attributed them to the new ichnospecies Thalassinoides callianas sae based on the find of an Anomura chela in a single burrow cast. The last author noted that burrows ofHowever, as usual all over the world, the decapod producer and their burrows almost never are found preserved together, allowing identifi cation of the decapod modus vivendi. described an unit with burrow mazes of Thalassinoides suevicus with hundreds of Mecochirus rapax as an obrution lagerstätte, in the lower Barremian from the Lusitanian Basin.Thalassinoides , Schaubcylindrichnus and Trichichnus are common (the latter is a deep-tier trace fossil produced by filamentous sulfide-oxidizing bacteria with a high tolerance for dysoxia ...

The gross morphology of Ophiomorpha overlaps with that of such ichnogenera as Ardelia, Gyrolithes, Teichichnus, and Thalassinoides, yet these burrow forms should be retained as separate taxa.

Several crustaceans producing Thalassinoides-like burrows are known to follow variable nutrition modes, from suspension or filter to deposit feeding (e.g., Gingras et al., 2008; Pervesler and Uchman, 2009). The draught-fill and the sandy nature of fill of the tubular tidalites indicate that burrows were passively ventilated and hence, currents ...
This study focuses on the tectono-sedimentary evolution through stages 2-4, while the main oil-bearing sedimentary rocks were deposited in the Bohai Bay Basin. The depositional system exhibited retrogradation and then progradation during the rifting stage 2 (43-36.7 Ma), retrogradation in stage 3 (36.7-32.8 Ma), and upward coarsening and ...Common Thalassinoides and Ophiomorpha burrows indicate that crustaceans were an important part of the infauna. Pervasive bioturbation resulted in a post-depositional homogenization of the sediments while all body fossils are preserved as (composite) internal moulds.Thalassinoides typically forms boxwork systems and networks and has visible short vertical shafts on bedding surfaces, with specimens being smooth, lack-ing wall reinforcements and mainly consisting of horizontal-branched burrows (Fig. 4).
