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.Thalassinoides ichnofabric reveals colonization of firmgrounds during prolonged times between erosion and deposition related to transgressive surfaces.

THALASSINOIDES EHRENBERG, 1944 Thalassinoides is an infaunal dwelling or feeding burrow. The inhabitant kept the bur-row open with self-induced water currents. In Cretaceous to Recent examples Thalas-sinoides traces were made by burrowing crus-taceans. Ehrenberg, 1944. Thalassinoides is an ichnogenus of trace fossil used to refer to "dichotomously or T-branched boxworks, mazes and shafts, unlined and unornamented".

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). The diameter of Thalassinoides varies little, commonly being in the range of 3-10mm, with some reaching ...Thalassinoides Ehrenberg, 1944: Overview; Taxon description. Yanin & Baraboshkin, 2013.

Abstract. Many horizons in the Marnoso-arenacea Formation contain rare to abundant trace fossils at numerous localities. Slope, fan, and basin-plain deposits have trace fossils dominated by the Nereites ichnofacies but include taxa from the Zoophycos ichnofacies plus Ohphiomorpha and Thalassinoides.Silicified boxwork of the ichnogenus Thalassinoides in the Silurian (Wenlockian) Racine Formation, Milwaukee, Wisconsin (USA) represents open-burrow systems that extended decimeters below the sediment surface in offshore carbonate muds of an intracratonic basin. The most completely-silicified burrows contain a core of organic-rich, spiculitic chert, a surrounding zone of chert, and an outer ...

The well preserved Thalassinoides specimens are attributed to the ichnospecies T. suevicus.Thalassinoides, widely distributed in the Mesozoic and Cenozoic, occurs also in shallow-water sediments in the Paleozoic (e.g., Palmer, 1978;Archer and Maples, 1984; ... wichita state shocker mascot 199 of 564. Trace fossils are fossils that preserve animal tracks or evidence of animal behaviors from the past. These trace fossils record trilobite behavior in the Cambrian of the Paleozoic.
