Trace fossils from Silurian and Devonian turbidites of the Chauvay area, southern Tien Shan, Kyrgyzstan. Annales Societatis Geologorum Poloniae, 79: 1-11. Abstract: The siliciclastic turbidite successions (Pul’gon and Dzhidala Formations) that crop out in the eastern part of the Chauvay River valley, are marked on geological maps as a belt of terrigenous deposits of Silurian- Devonian age. They resemble deposits of overbank areas and deposilional lobes of deep sea fans, and display common trace fos sils particularly on lower surfaces of sandstone beds. Sixleen ichnolaxa representing four morphological groups have been dislinguished. The trace fos sil as semblages suggest their affiliation to the Nereites ichnolacies. Various branched, prelurbidlte forms predominate in both examlned units, although the assemblages of individual units differ slightly in composition. In the Pulg’on Formation, small, densely distributed burrows commonly occur on lower surfaces of sandstone beds. Shallow burrowing depth together with relatively low diversity trace fossil assemblages indicate lowered oxygenation of the sea floor. Key words: Tien Shan; Kyrgyzstan; Silurian-Devonian; turbidites; trace fossils. Manuscript received 12 August 2008, accepted 26 February 2009 INTRODUCTION described from these deposits. -

[email protected] ISMAR DE SOUZA CARVALHO Departamento de Geologia, Instituto de Geociências, UFRJ, 21949-900, Cidade Universitária, Rio de Janeiro, RJ, Brazil. [email protected] ABSTRACT – The Bauru Group is a sequence at least 300 m in thickness, of Cretaceous age (Turonian- Maastrichtian), located in southeastern Brazil (Bauru Basin), and consists of three formations, namely Adamantina, Uberaba and Marília. Throughout the Upper Cretaceous, there was an alternation between severely hot dry and rainy seasons, and a diverse fauna and flora was established in the basin. The ichnofossils studied were found in the Adamantina Formation outcrops and were identified as Arenicolites isp., ?Macanopsis isp., Palaeophycus heberti and Taenidium barretti, which reveal the burrowing behavior of the endobenthic invertebrates. There are also other biogenic structures such as plant root traces, coprolites and vertebrate fossil egg nests. The Adamantina Formation (Turonian-Santonian) is a sequence of fine sandstones, mudstones, siltstones and muddy sandstones, whose sediments are interpreted as deposited in exposed channel-bars and floodplains associated areas of braided fluvial environments. Key words: Bauru Basin, ichnofossils, late Cretaceous, continental palaeoenvironments, Adamantina Formation. RESUMO – O Grupo Bauru é uma seqüência de pelo menos 300 m de espessura, de idade cretácica (Turoniano- Maastrichtiano), localizada no Sudeste do Brasil (bacia Bauru), e consiste das formações Adamantina, Uberaba e Marília. -

Continental Invertebrate and Plant Trace Fossils in Space and Time: State of the Art and Prospects
48 3RD INTERNATIONAL CONFERENCE OF CONTINENTAL ICHNOLOGY, ABSTRACT VOLUME & FIELD TRIP GUIDE Continental invertebrate and plant trace fossils in space and time: State of the art and prospects M. GABRIELA MANGANO1 *, LUIS A. BUATOIS1 1 Department of Geological Sciences, University of Saskatchewan, 114 Science Place, Saskatoon SK S7N 5E2, Canada * presenting author, [email protected] Continental invertebrate ichnology has experienced a substantial development during the last quarter of century. From being a field marginal to mainstream marine ichnology, represented by a handful of case studies, continental ichnology has grown to occupy a central position within the field of ani- mal-substrate interactions. This evolution is illustrated not only through the accumulation of ichnolog- ic information nurtured by neoichnologic observations and a detailed scrutiny of ancient continental successions, but also through the establishment of new concepts and methodologies. From an ichnofacies perspective, various recurrent associations were defined B( UATOIS & MÁNGANO 1995; GENISE et al. 2000, 2010, 2016; HUNT & LUCAS 2007; EKDALE et al. 2007; KRAPOVICKAS et al. 2016), a situation sharply contrasting with the sole recognition of the Scoyenia ichnofacies as the only valid one during the seventies and eighties (Table 1; Fig. 1). The ichnofacies model now includes not only freshwater ich- nofacies, but also terrestrial ones, most notably those reflecting the complex nature of paleosol trace fossils (GENISE 2017). Trace fossils are now being increasingly used to establish a chronology of the colonization of the land and to unravel the patterns and processes involved in the occupation of ecospace in continental set- tings (e.g. BUATOIS & MÁNGANO 1993; BUATOIS et al. -
Trace Fossils from Lower Palaeozoic Ocean-Floor Sediments of the Southern Uplands of Scotland M
Transactions of the Royal Society of Edinburgh: Earth Sciences, 73, 67-87, 1982 Trace fossils from Lower Palaeozoic ocean-floor sediments of the Southern Uplands of Scotland M. J. Benton ABSTRACT: The Ordovician and Silurian rocks of the Southern Uplands of Scotland have been interpreted as sediments deposited on the northern margin of the Iapetus Ocean. Trace fossils are abundant at many localities in ocean-floor turbidites and mudstones that usually lack all other evidence of life. Twelve ichnogenera are present, and they are mainly meandering locomotion and feeding trails and burrow networks: Dictyodora, Caridolites, Helminthoida, Neonereites, Nereites, Protovirgularia, Gordia, Megagrapton, Paleodictyon, Chondrites, Plano- lites and Skolithos. The trace fossils occur in at least five distinct assemblages and the composition of these was probably controlled by the frequency and nature of the turbidity currents, and possibly by the oxygen content of the mudstones. Where turbidity currents were weak, abundant Dictyodora, together with Caridolites, Neonereites, Nereites, Protovirgularia and Gordia occur in various combinations. Where currents were stronger, traces such as Gordia, Paleodictyon and Megagrapton may be exhumed and cast on turbidite soles, and the sand may contain Skolithos. The 'deep-sea' Nereites trace fossil facies is divisible into several assemblages, presumably environmentally controlled.

Manuscript received November 23, 2007; revised manuscript accepted March 7, 2008. Abstract whether Agadirichnus from the Late Cretaceous of Morocco (foot length 10–12 cm) is pterosaurian. Most Cretaceous sites At least 50 pterosaur track sites have been reported from Late represent lacustrine, not marginal marine, habitats. Both Juras- Jurassic through Late Cretaceous localities in North America, sic and Cretaceous assemblages often contain very high track Europe, East Asia and South America, plus one possible site densities and a range of track sizes associated with invertebrate from north Africa. Tracks from these sites have been assigned traces. This suggests that diverse pterosaurian fl ocks may have to 11 ichnospecies in four ichnogenera. Of these, Pteraichnus congregated in large numbers to feed. Some assemblages reveal is by far the most prevalent, well-preserved, and represented swim tracks that suggest pterosaurs fl oated in shallow water, by multiple (presently eight) ichnospecies. The majority of touching the submerged substrate with only their hind feet. Pteraichnus tracksites are Late Jurassic or earliest Cretaceous These swim track assemblages also contain possible beak traces (Berriasian) in age. -
Late Carboniferous Tropical Dryland Ecosystem, Joggins, Nova Scotia1
Report of Activities 2002 181 Late Carboniferous Tropical Dryland Ecosystem, 1 Joggins, Nova Scotia H. J. Falcon-Lang and J. H. Calder Museum dioramas usually depict the Late Carboniferous tropical zone as being covered by humid rainforests composed of densely spaced tree-sized lycopsids. However, new evidence from the Langsettian fossil cliffs of Joggins, Nova Scotia suggests that this may only be half the story. At this classic site, grey coal-bearing units deposited in humid wetland coastal plain environments and containing 'normal' lycopsid-dominated rainforest vegetation are interbedded with red bed units. The red bed units, which are the focus of this paper, were deposited in seasonal dryland alluvial environment and contain an unusual floral and faunal assemblage. Depauperate floral remains in the deposits of anastomosing river channels, crevasse splays, and overbank muds are dominated by cordaite gymnosperms (Cordaites leaves, Artisia pith casts, and woody Dadoxylon trunks and branches; >80% of specimens). Present in subordinate numbers are pteridosperms (Eusphenopteris), sphenopsids (Calamites) and lycopsids (Sigillaria). A high proportion of this plant material has been charred in wildfires. Faunal remains associated with waterhole deposits in seasonally dry channels include land snails (Dendropupa), giant freshwater clams (Asterodonta) and the pelvic girdle and jaw of loxomatid reptiles. These data indicate that Late Carboniferous dryland tropical environments supported low diversity, fire-prone gymnospermous vegetation consisting mostly of shrubs or small trees inhabited by a unique fauna. At Joggins, gymnospermous dryland ecosystems repeatedly alternated with lycopsid wetland ecosystems, perhaps in response to glacial-interglacial climate rhythms. 16th European Palaeobotany and Palynology Conference, Athens, Greece; in Abstracts with Programs, p. -

The Earliest Bioturbators As Ecosystem Engineers

T. CALLOW1,3 & DUNCAN MCILROY1 1Department of Earth Sciences, Memorial University of Newfoundland, Prince Philip Drive, St John’s, NL, A1B 3X5, Canada 2Geology, School of Environmental Sciences, University of Hull, Cottingham Road, Hull HU6 7RX, UK 3Statoil ASA, Stavanger 4035, Norway *Correspondence: [email protected] Abstract: By applying modern biological criteria to trace fossil types and assessing burrow mor- phology, complexity, depth, potential burrow function and the likelihood of bioirrigation, we assign ecosystem engineering impact (EEI) values to the key ichnotaxa in the lowermost Cambrian (Fortunian). Surface traces such as Monomorphichnus have minimal impact on sediment properties and have very low EEI values; quasi-infaunal traces of organisms that were surficial modifiers or biodiffusors, such as Planolites, have moderate EEI values; and deeper infaunal, gallery biodiffu- sive or upward-conveying/downward-conveying traces, such as Teichichnus and Gyrolithes, have the highest EEI values. The key Cambrian ichnotaxon Treptichnus pedum has a moderate to high EEI value, depending on its functional interpretation. Most of the major functional groups of mod- ern bioturbators are found to have evolved during the earliest Cambrian, including burrow types that are highly likely to have been bioirrigated. In fine-grained (or microbially bound) sedimentary environments, trace-makers of bioirrigated burrows would have had a particularly significant impact, generating advective fluid flow within the sediment for the first time, in marked contrast with the otherwise diffusive porewater systems of the Proterozoic. -
