Thalassinoides.

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. Thalassinoides and Ophiomorpha, therefore, are Ammonitico); D) Miocene slope to basin plain systems typical cross-facies trace fossils (Frey et al., 1978), which with deep water turbidite deposits, northern Apennines usually spread in every environments during the Phan- (Macigno and Marnoso Arenacea flysch deposits). erozoic and occur from ...The burrows are invariably associated with Thalassinoides and show similar diameters, supporting a crustacean trace-maker. The aim of this paper is threefold: ( ...Introduction. Thalassinoides is one of the best-known trace fossils among ichnopaleontologists. It was first described by Woodward (1830), as a fossil fucoid (seaweed), and gave it a generic name Thalassinoides.Subsequently, Ehrenberg (1944; p. 358) introduced this genus as an invertebrate trace fossil using specimens from the Burdigalian Stage of the …

They usually occur in dense associations. The dimensions of the burrows may reflect the environmental energy level.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 Ehrenberg, 1944 DESCRIPTION: Three-dimensional boxwork of branched cylindrical burrows interconnected by vertical shafts. BEHAVIOR (S): Deposit-feeding and dwelling. ENVIRONMENTAL SETTINGS: Shallow marine and deep marine turbidites. POSSIBLE TRACEMAKERS: Crustaceans GEOLOGIC RANGE: Cambrian-recent Remarks: Preserved as sand-filled epirelief burrows in thin silty shale and fine-grained sandstone beds. The specimen is very similar to Thalassinoides Ehrenberg, 1944, except for the sinuosity of the horizontal elements and therefore are considered to have been produced by deposit feeder crustaceans, probably decapods (de Gibert and Martinell ...

Based on cross-cutting relationships and differences in morphology, diameter, and burrow-filling sediments, numerous ichnospecies of Thalassinoides are discernable throughout the Austin. Variations in preservation quality exhibited by successive generations of ichnofossils record progressive changes in substrate consistency.
