Netto, R.G. 2018: An integrative ichnological and taphonomic approach in a transgressive-regressive cycle: a case study from Devonian of Paran a Basin, Brazil. Lethaia, Vol. 51, pp. 15-34.The palaeoenvironmental context of a section of the Devonian Ponta Grossa Formation (Paran a Basin) was examined using an integrated ichnological and taphonomic approach. Three taphofacies (T-A, T-B and T-C) and six ichnofabrics are recognized. T-A is mainly composed of disarticulated organisms and is associated with Chondrites, Planolites-Palaeophycus, Asterosoma-Zoophycos and Asterosoma-Chondrites ichnofabrics, representing the Cruziana ichnofacies. The upward increase in diversity and abundance of body fossils for Taphofacies A can be explained by changes in sedimentation rates during aggradational to progradational phases. T-B beds, represented by articulated brachiopods, occur in distal tempestites associated with the Skolithos ichnofabric (Skolithos ichnofacies) and represent higher hydrodynamic energy and oxygenation than in T-A. Taphofacies C, characterized by a mix of articulated and disarticulated organisms, generally lacks bioturbation except for Chondrites ichnofabrics occurring only at the bed tops, suggesting low substrate oxygenation and low-energy conditions. T-C indicates the maximum transgression in the T-R cycle, characterizing it as a good indicator of maximum flooding surfaces. The composite Asterosoma-Teichichnus ichnofabric (bioturbation degree 5) occurs in layers without body fossils and represents suites of the Cruziana ichnofacies. This likely reflects intense intrastratal activity at all substrate levels, which facilitated the oxygenation of the substrate disallowing the preservation of organism remains. This observation indicates that the bioturbation is an important factor controlling the loss of taphonomic information within the TAZ, mainly when associated with detritus-feeding trace fossils. □ Devonian shales, Gondwana, ichnofacies, marine siliciclastic deposits, palaeoenvironmental analysis, taphofacies.Daniel Sedorko ✉ [sedorko@edu.unisinos.br], and Renata G.

“…The new ichnospecies belongs to the genus Palaxius because of the crescentic, internal canals. To our knowledge, seven Palaxius ichnospecies with ten internal canals have been described (Elliot, 1962; Palik, 1965; Kennedy et al, 1969; Senowbari-Daryan, 1979; Kuss and Senowbari-Daryan, 1992; Senowbari-Daryan and Kuss, 1992; Blau et al, 1993; Blau and Grün, 2000; Becker and Chamberlain, 2006; Peckmann et al, 2007; Kietzmann and Palma, 2010, 2014; Kietzmann et al, 2010). From the size and arrangement of crescentic canals, the south Florida specimens resemble the Oligocene P .…”

Palaxius floridanus n. isp., a new structured callianassid crustacean microcoprolite from the Pleistocene of south Florida

The crustacean microcoprolite Palaxius floridanus n. isp. is described from shallow-water carbonate platform deposits of Pleistocene limestones of south Florida. Palaxius floridanus n. isp. occurs in moderate-energy packstones and grainstones of the oolite facies of the Miami Limestone, and in skeletal packstones of the Key Largo Limestone, ranging in age from marine isotope stage (MIS) 11 to MIS 5a (ca. 400–80 kyr BP). The new ichnospecies resembles P. decemlunulatus, which has been described previously from Oligocene deposits. Late Jurassic and Late Cretaceous forms described as P. decemlunulatus belong to a new ichnogenus and new ichnospecies, respectively, yet to be described.

“…Kietzmann & Palma () regarded Fundalutum dakhalense as ‘a poorly preserved specimen of Palaxius caucaensis in which narrower parts of the canals are not preserved’. In that case, P. caucaensis Blau et al ., would become a junior synonym of F. dakhalense , the latter which then should be included in the ichnogenus Palaxius as a new combination.…”
