“…It is interpreted as fodinichnia or equilibrichnia of deposit feeders (Kim et al 2002, Davies et al 2009Loughlin and Hillier 2010). Zonneveld et al (2012) proposed fish, worms, insects and anemones as the potential tracemakers of both Skolithos and Monocraterion. In non-marine settings Skolithos may be produced even by insects: midge larvae, tiger beetle, arachnids, ants or plants (Alpert 1974;Häntzschel 1975;Pemberton et al 1984;Bjerstedt 1988;Pemberton and Jones 1988;Gillette et al 2003;Schlirf and Uchman 2005;Morrisey et al 2006Morrisey et al , 2012Singh et al 2008;Knaust 2012).…”

The following trace fossils have been recognised in the Lower Muschelkalk of Raciborowice Gorne (North Sudetic Synclinorium, SW Poland): Archaeonassa fossulata, Balanoglossites triadicus, ?Gastrochaenolites isp., Lockeia isp., Palaeophycus tubularis, Palaeophycus isp., ?Planolites beverleyensis, P. montanus, Planolites isp., ?Protovirgularia isp., Rhizocorallium commune var. auriforme, R. commune var. irregulare, R. jenense, Skolithos linearis, Thalassinoides suevicus and Trypanites weisei. Coprolites and an unidentified trace fossil A are also described. The trace fossils allow the discrimination of five ichnoassociations in the Raciborowice Gorne section: (IA 1) Rhizocorallium- Pholeus, (IA 2) Rhizocorallium-Palaeophycus, (IA 3) Thalassinoides, (IA 4) Trypanites-Balanoglossites and (IA 5) Planolites-Palaeophycus. The Lower Muschelkalk succession was deposited on a shallow carbonate ramp affected by frequent storms. Deposition commenced with sedimentation in a restricted lagoon on the inner ramp with a short episode of sabkha formation. It continued on the middle and outer ramp and then on a skeletal shoal of the outer ramp and in an open basin. Ichnoassociation IA 5 is related to a maximum transgression that commenced with the deposition of the Spiriferina Bed and which probably marked the opening of the Silesian-Moravian Gate. The basin underwent two shallowing episodes, as evidenced by ichnoassociations IA 3-IA 4, resulting in the formation of hardgrounds. Bathymetric changes in the Raciborowice Gorne section correspond well with a general transgressive trend in the Germanic Basin.

“…The casts of the U-shaped spreiten burrows were carefully observed. The tube imprint shows the clear upward convex lunate back-fill menisci, which indicate the downward movement of the trace-maker in the substrate (Zonneveld et al, 2012). The D. parallelum in Bed 49 was about 82.0 mm in depth, and the limbs are 20.0 mm apart and 3.2 mm in diameter.…”

Trace fossils are known to be good indicators of sedimentary environments (Knaust and Bromley, 2012). The type, morphology, and diversity of trace fossils are now known to be a proxy to paleoenvironmental factors, including energy level, substrate stability, salinity variations, and oxygenation levels (Curran, 1985;Ekdale, 1988;Knaust and Bromley, 2012). The most significant advantage of trace fossils is that they are autochthonous indicators of paleoecological conditions (Bromley, 1996). In most cases, trace fossil data contribute to a better understanding of the sediments from the perspective of organism-substrate interactions (Uchman et al., 2004).The Lower Devonian sediments of the western Yangtze Plate are divided into the Pingyipu, Ganxi, Ertaizi, and Yangmaba formations, known for their well-exposed and complete stratigraphic record and long history of investigations (Hou et al., 1988). Several aspects of the sedimentology, paleontology, sequence stratigraphy, and isotope geochemistry of the mentioned formations in the Ganxi section (Figures 1a and 1b) were studied over the last fifty years (e.g., Xian et al., 1995;Zheng and Liu, 1997;Liao and Ma, 2007). Lower Devonian trace fossils of the region are poorly known. Lin et al. (1986) mentioned the presence of Diplocraterion and Thalassinoides in the Pingyipu Formation. Yang et al. (1988) listed some trace fossils from the studied units, including Arenicolites, Chondrites, Cruziana, Dimorphichnus, Helminthopsis, Phycodes, Planolites, Skolithos, Thalassinoides, and Zoophycos. Moreover, in recent years, a variety of wellpreserved trace fossils have been found and recorded in the Lower Devonian of the Ganxi section. The aim of the present paper is to provide a detailed ichnological and sedimentological analysis of the Ganxi section. Geological settingThe studied area is located in the northwestern part of the Upper Yangtze Plate and belongs to the Lower Paleozoic Longmenshan Basin (Figures 1c and 1d). The Devonian strata in this region were deposited on a continental margin Abstract: Abundant and diverse trace fossils occur in the littoral-neritic sediments recording an Early Devonian transgression in South China. The well-exposed Ganxi section is located in the Longmen Mountain 100 km northwest of Chendu, Sichuan. The Lower Devonian strata are dominated by sandstones, siltstones, muddy shales, limestones, bioclastic limestones, and muddy limestones. About thirteen ichnogenera were systematically described, including Arenicolites, ?Balanoglossites, Chondrites, Cylindrichnus, Diplocraterion, Planolites, Palaeophycus, Phycodes, Rhizocorallium, Rusophycus, Skolithos, Thalassinoides, and Zoophycos. Six trace fossil associations under different sedimentary environments have been recognized as follows: the Skolithos and Diplocraterion-Skolithos associations mainly consist of domichnia derived from a high-energy zone of the foreshore to upper shoreface; the Rusophycus-Phycodes association is characterized by fodinichnia and cubichnia generated in a lower-energy zone of...

“…We sampled and described the 165 m thick stratigraphic sequence of alluvial deposits in June and July, 2009. Additional samples were taken from a nearby exposure that contained 8 paleosols associated with bird tracks and other trace fossils discussed in Zonneveld et al (2011Zonneveld et al ( , 2012 and Zaim et al (2011Zaim et al ( , 2014.…”

“…Burial depths of sediments in the Ombilin Basin do not exceed 2200 m (Moss and Carter, 1996). This overburden was minimal and ichnofossils associated with the KBT section show no evidence of compaction (Zonneveld et al, 2011(Zonneveld et al, , 2012. Furthermore, applying the decompaction method of Sheldon and Retallack (2001) to these paleosols yielded very low compaction estimates (Supplementary Information Table S3).…”
