Lower shoreface deposits are heavily bioturbated by Scolicia, Asterosoma, Thalassinoides, Teichichnus, Palaeophycus and other elements of the Cruziana Ichnofacies whereas middle shoreface sandstone beds contain sand-filled burrows of the Skolithos Ichnofacies. Deltaic deposits record coarsening-upward successions with evidence of …Calcareous muddy contourites with Thalassinoides and Chondrites from Cyprus. Samples with Thalassinoides reworked by Chondrites were selected from the contouritic calcareous mud of Cyprus (Fig. 4A, B). The infilling material of Thalassinoides, reworked by Chondrites burrows, mainly consists of the same muddy material as the host sediment.SELLWOOD, B. W. 1971.

Trace fossils Thalassinoides horizontalis, Thalassinoides callianassa and Planolites developed in the Longwangmiao Formation, and the sharp edges of mottled dolomite are similar to these trace fossils. The beds are intensely bioturbated.This work describes the occurrence of numerous, nearly intact Mecochirus rapax populations within Thalassinoides suevicus burrows in the Lower Cretaceous Boca do Chapim Formation.

Under more ...Mar 1, 2003 · Thalassinoides has been attributed to various tracemakers, according to the occurrence of associated body fossils and/ or faecal pellets, or to a comparison with modern analogues, but decapod ... Common Thalassinoides and Ophiomorpha burrows indicate that crustaceans were an important part of the infauna, associated by irregular echinoids and polychaetes. Pervasive bioturbation resulted in a post-depositional homogenization of the sediments. All body fossils are preserved as internal moulds due to early diagenetic carbonate dissolution.Thalassinoides were produced by a deep burrowing or- ganism, probably a thalassinid crustacean. Both are attributed to the activities of a single organism ...Seven ichnofabrics including Thalassinoides (Th), Zoophycos‒Phycosiphon (Zo-Ph), Skolithos‒Thalassinoides (Sk-Th), Zoophycos‒Diplocraterion (Zo-Di), Thalassinoides‒Rhizocorallium (Th-Rh), Zoophycos‒Arenicolites (Zo-Ar) and Chondrites‒Phycosiphon (Ch-Ph) have been identified in the studied succession.Thalassinoides is a type of unlined, open, branching, three-dimensional burrow system that serves as both a dwelling and foraging structure. It has a long ...and Thalassinoides (Carmona et al., 2013). Some burrowers penetrated several tens of centimetres deep when producing Asterosoma, Scalichnus, Siphonichnus, Thalassinoides and Ophiomor-pha. Furthermore, composite trace fossils occur as the fill of Thalassinoides was reworked by producers of Chondrites and Taenidium-like traces.Aug 31, 2007 · rows of Thalassinoides isp. and other spiral burrows. are characteristically present on bedding planes (Fig-ure 5D, E).
