Such burrows are made by a number of organisms, including the sea anemone Cerianthus, Balanoglossus and fishes, but are most closely associated with decapod crustaceans of the (former) infraorder Thalassinidea.(a) Thalassinoides with long scratches on burrow floor (scale 5 cm).

The completeness of ...Thalassinoides An ichnoguild of branched, horizontal to slightly inclined burrows or a burrow system, formed by suspension feeders just below water, at the sediment interface. They usually occur in dense associations. The dimensions of the burrows may reflect the environmental energy level. Thalassinoides burrows are typical of clastics and detrital …This work describes the occurrence of numerous, nearly intact Mecochirus rapax populations within Thalassinoides suevicus burrows in the Lower Cretaceous Boca do Chapim Formation.

Jan 1, 2011 · Brackish-water trace-fossil suites generally comprise low-diversity, comparably diminutive trace fossils including forms such as Cylindrichnus, Planolites, Thalassinoides, Teichichnus, Arenicolites, Skolithos and cryptobioturbation. A problem with this method is that tidal currents and brackish-water do not always accompany one another. With the exception of Thalassinoides type IV, all The following interpretation of the trophism of the the studied Thalassinoides both in the Calcari Grigi and trace makers and of the ecological significance of the in the Sácaras Formation have a sub-circular cross section different Thalassinoides forms are based on the model or narrowing, thus ... ….

Fossiliferous calcareous nodules and Thalassinoides burrows lined with pyrite (Loc. 1504) are common in the sandy mudstone. At Loc. 1407, alternated beds composed of gravelly sandstone and sandy dark gray mudstone are characterized by lenticular to flaser bedding with bimodal current ripple laminations.Thalassinoides burrows dominated firmground in Maastrichtian to late Thanetian phosphatic succession of Iraq. Discover the world's research. 25+ million members; 160+ million publication pages;Some Thalassinoides are large with diameters up to 10 cm. The Ophiomorpha do not branch and have relatively small diameters. Most Ophiomorpha, Cylindrichnus, Skolithos, Chondrites and Diplocraterion were observed in silty units. Muddy tidal flats can be characterized by relatively high ichnofabric indices and diversity with abundant Thalassinoides.
