Thalassinoides.

Thalassinoides. A complex network of branching to interconnected burrows that extends both vertically and horizontally, with the burrow mass often defining a single bed. The burrow walls are lined, which indicates a dwelling burrow. Thalassinoides in some may cases may closely resemble Ophiomorpha, but differs in the absence of fecal pellets in ...Thalassinoides burrows, sparse bivalves and the presence of glauconite peloids demonstrate periodic marine incursions across the coastal plain which resulted in reworking of siliciclastics in the littoral zone during marine transgressions.

Diameter of tunnels variable, between 7 and …Thalassinoides burrow systems have been described many times in various types of marine depositional systems. They are usually interpreted as the work of deposit feeders or as domiciles in well-oxygenated sediments, and are attributed by most workers to endobenthic crustaceans (summarized in Bromley and Frey, 1974, Ekdale et al., 1984, …appearance of Thalassinoides in the latest Early Triassic represents a less-complex version than Permian Thalas-sinoides in the western United States.

Zonneveld, pers. comm.,The burrows attributed to Thalassinoides suevicus are predominantly horizontal systems, and visible at sedimentary interfaces preserved as convex hyporelief or providing a nodular fabric to bedding sections.The burrows are large and characterized by an irregular width that can exceed 110 mm, and their length can reach more than 1 m bending occasionally.

The most distinctive and sometimes superabundant shelf and deep-sea crustacean burrows are represented by the trace fossils (ichnotaxa) Spongeliomorpha Saporta, 1887, Ophiomorpha Lundgren, 1891 and Thalassinoides Ehrenberg, 1944.
