Scares Ophiomorpha nodosa and Thalassinoides in these sandstones indicate a stressful condition such as sandy mobile substrate, turbidity and highly salinity fluctuation in the sedimentary ...Thalassinoides and Zoophycos — and, additionally, the increase in their individual size — can be interpreted as a sign of improved oxygenation (Bromley and Ekdale 1984 ;Thalassinoides isp. and Teichichnus rectus occur in the sandstone. Bioturbation intensity is low (BI = 0-1) in the sandstone, and high (BI = 5-6) in the mudstone, exhibiting a mottled texture, whereas sandstone beds exhibit sharp boundaries. FA3 is situated above lower offshore (FA2), and underneath offshore transition deposits (FA4 and FA5).Thalassinoides paradoxicus (Woodward, 1830) is a prevalent and frequently reported ichnotaxon, but given its early erection and subsequent revisions, it now is poorly understood and lumps together ...

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.Significance. Strained 1.7-billion-year-old metasedimentary rocks in southwestern Australia contain traces of burrowing animals, structures only known from the last half billion years of Earth history. As metamorphic events had made the sediment too hard for burrowing by ∼1.2 billion years ago, it has been suggested that the burrows were made ...Thalassinoides isp. and Teichichnus rectus occur in the sandstone. Bioturbation intensity is low (BI = 0-1) in the sandstone, and high (BI = 5-6) in the mudstone, exhibiting a mottled texture, whereas sandstone beds exhibit sharp boundaries. FA3 is situated above lower offshore (FA2), and underneath offshore transition deposits (FA4 and FA5).By way of comparison, the Cruziana Ichnofacies is typified by trace fossils such as Asterosoma, Scolicia, Planolites, Palaeophycus, Thalassinoides, and Teichichnus. All of these trace fossils have modern analogs that strongly support the interpretation of these biogenic structures as deposit-feeding traces in resource-rich sediments ( Dworschak ...In summary the Skolithos- Thalassinoides forms the part of fine grained sand units.

Thalassinoides-burrows are predominantly vertical and the burrow fill material may present tortuous and high permeability pathways through the low permeability mudstone matrix. Therefore, the ...The validity of Ophiomorpha nodosa as a marine indicator is reviewed in the light of its occurrence in the Wealden Marls of the Isle of Wight, where it is associated with sediments considered to be of marsh and levée facies marginal to a brackish lagoon. Recent research indicates that modern Ophiomorpha, Thalassinoides and possibly Spongeliomorpha type burrows occur in fresh, brackish and ...
