The Willwood Formation is a sedimentary sequence deposited during the late Paleocene to early Eocene, or Clarkforkian, Wasatchian and Bridgerian in the NALMA classification. [1] [2]Chattanooga Shale in TN and northern AL is the distal fringe of the black gas shales in the southwestern Appalachian basin. In central TN, where the unit ranges in thickness from a featheredge to more than 35 ft it is divided into the Dowelltown Member below and the Gassaway Member above.Planolites belongs to the most widespread and ubiquitous trace fossils, being frequently reported from floodplain and channel facies (Buatois and Mangano 1993). A variety of vermiform animals including insect larvae can be considered as tracemakers (Pemberton and Frey 1982 ; Buatois and Mangano 1993 ), and the presence of fluvial …Planolites is a facies-crossing form and can be found in most settings, from freshwater to deep marine (Rodríguez-Tovar and Uchman, 2004, Rodríguez-Tovar and Uchman, 2017; Rodríguez-Tovar et al., 2009). It is interpreted as a pascichnion, probably produced by numerous different organisms (Pemberton and Frey, 1982; Keighley and Pickerill, 1995).Resources. A plant pigment is any type of colored substance produced by a plant. In general, any chemical compound which absorbs visible radiation between about 380 nm (violet) and 760 nm (ruby-red) is considered a pigment. There are many different plant pigments, and they are found in different classes of organic compounds.Interbedded sandstones and mudstones contain Teichichnus, Planolites, Terebellina, Arenicolites, Bergaueria, Rosselia, Asterosoma, Cylindrichnus, Thalassinoides, and fugichnia. Burrowed incised valley conglomerates and pebbly sandstones mainly record channel fills of tidal inlets or flood-tidal deltas at wave-dominated estuary mouths.Ophiomorpha is the most abundant ichnogenus, and appears in the thick turbiditic sandstone beds; Thalassinoides is common, Planolites rare, and Zoophycos and Spirophyton is occasionally found.Planolites, Rosselia, root structure, Scolicia, Skolithos, Spirophyton, Teichicnus, Thalassinoides, and Zoophycos. Eight ichnofossils association can be determined from each well (Table 1 and 2). Each ichnogenera that are used as a basis for ichnofossils association are shown in Figure 3 (Well-1) and Figure 4 (Well-2).Seven ichnofossil assemblages, i.e., Cruziana-Rusophycus, Planolites-Palaeophycus, Cruziana problematica, Diplichnites, Cochlichnus anguineus, Bergaueria perata and Psammichnites gigas have been recognized in the Lower Quartzite to Arkosic Sandstone members of the Koti Dhaman Formation.
