NETWORK THEORY IN ICHNOLOGY: FROM BEHAVIOURAL TOPOLOGY TO THE DEPOSITIONAL ENVIRONMENT
This study aims to (1) develop quantitative approaches for the study of ichnological systems; (2) model, for the first time, ichnosites as networks; (3) analyze the response of ichnological systems to global dynamics, with particular regard to Late Paleozoic fluvial-influenced settings. In this …

The Cambrian: Sedimentary controls on marine ichnology and stratigraphic time at outcrop
The Cambrian Period represents a pivotal chapter in Earth’s history, marked by the expansion of vast epeiric seas and major evolutionary innovations associated with the Cambrian Explosion. Evolutionary reconstructions can be influenced by sedimentary processes, which were heterogeneous across …

Sedimentology, ichnology and sequence stratigraphy of the Lower Cambrian Gog Group, southern Rocky Mountains, Canada
… focuses on the stratigraphy, sedimentology and ichnology in the Bow Valley region, specifically the sector from Mount Assiniboine northwest to the North Saskatchewan River. The objectives of this project were several-fold: (1) revise the existing stratigraphic nomenclature; (2) document the …

Sedimentology, ichnology, and stratigraphic architecture of the upper Devonian-lower Mississippian Bakken Formation, west-central Saskatchewan
The Upper Devonian-Lower Mississippian Bakken Formation has recently become a prolific producer of light gravity oil in southeastern Saskatchewan since the advent of horizontal drilling and multi-stage hydraulic fracture technologies, which has resulted in an increase in geological studies within …

SEDIMENTOLOGY, ICHNOLOGY, AND SEQUENCE STRATIGRAPHY OF THE MIOCENE OFICINA FORMATION, ORINOCO OIL BELT, EASTERN VENEZUELA BASIN
The Lower Miocene Oficina Formation is widely distributed in the subsurface of the Orinoco Oil Belt of eastern Venezuela. Despite its economic importance as one of the most important hydrocarbon reservoirs worldwide, little is known about its sedimentologic, ichnologic and sequence-stratigraphic …

Stratigraphy, Sedimentology, and Ichnology of the Middle Cambrian to Lower Ordovician Deposits in Subsurface Western Canada
During the past decade, the economic importance of the preserved Cambrian-Ordovician succession in subsurface Alberta and Saskatchewan has increased considerably, mainly due to the development of geothermal, carbon sequestration, and helium exploration and extraction projects. Despite this, the …

Ichnology and sedimentology of large tetrapod burrows in the latest Early Triassic Katberg Formation, south-eastern main Karoo Basin, South Africa
… (animal behaviour) processes are important in ichnology and paleoenvironmental reconstruction. The analyses have therefore been undertaken through a multidisciplinary approach based on ichnological, sedimentological, petrographical, stratigraphic and paleontological evidence, gathered both in …

Depositional environments, ichnology and diagenesis of the upper Frobisher-Alida beds of the Elkhorn Ranch and Roughrider fields of western North Dakota
<p> The upper Frobisher-Alida interval of western North Dakota was studied in order to determine the depositional envirornnents, bioturbation features, and the diagenetic history of these carbonate and evaporite rocks. </p><p> Detailed examination resulted in the identification of six distinct …

Understanding the theatre of terrestrialization: Silurian-Devonian sedimentary landscapes and continental ecosystems
… new field data comparing the sedimentology and ichnology of these Australian sections with other original data from successions in Europe and North America, to present a more global perspective to the global questions surrounding the terrestrialization process. Alongside original observations …

Faunal, sedimentological and geochemical indicators of dysoxia in Cretaceous marine sediments
… include: - sedimentological proxies, including ichnology, sedimentology, taphonomy and pyrite framboid size distribution; - faunal proxies including macrofaunal properties, and biofacies models; - geochemical proxies, including trace-element abundances [Mo, V, Ni, Mn], element ratios and …

Process Sedimentology and Three-Dimensional Facies Architecture of a Fluvially Dominated, Tidally Influenced Point Bar: Middle McMurray Formation, Lower Steepbank River Area, Northeastern Alberta, Canada
… dominated sand deposition and brackish-water ichnology of the mud beds represents the annual migration in position of the tidal and salinity nodes caused by fluctuations in fluvial discharge. Recognition of metre-scale cycles (MSCs) of alternating sandier and muddier intervals within the IHS …

The Middle to Late Cretaceous microbiostratigraphy (foraminifera) and lithostratigraphy of the Cauvery Basin, Southeast India
… study demonstrates how palaeontology (including ichnology) in conjunction with sedimentology and stratigraphy is used to apply sequence stratigraphy concepts to the late Turonian-Coniacian succession in the Basin. A comprehensive study of Teredolites-infested fossil wood documents the …

Bioturbation in Supratidal Carbonates: Georadar Characterization of the Patterns and Structure of Decapod Burrows
Bioturbation in supratidal carbonate substrates has only recently received attention from ichnologists, relying primarily on traditional ground-based techniques. This study is the first high-resolution geophysical investigation of three decapod species inhabiting adjacent coastal biotopes on San …

Ichnotaxonomic assessment of Mazon Creek area trace fossils, Illinois, USA
The Francis Creek Shale Member (FCSM) of the Mid-Pennsylvanian Carbondale Formation along Mazon Creek in northern Illinois is known for soft-bodied organisms preserved within siderite concretions. Trace fossils, though less well known, also occur in concretions. Several hundred trace-fossil-bearing …

THE ICHNOLOGICAL AND DEPOSITIONAL CONTEXT OF BIOERODED TRICERATOPS BONES FROM THE MAASTRICTHIAN FRENCHMAN FORMATION OF SOUTHERN SASKATCHEWAN, CANADA
Previous studies on osteic bioerosion trace fossils on dinosaur bones have contributed to our understanding of Mesozoic terrestrial paleoecology and depositional environments. In many cases, body fossils of the inferred tracemaker are either exceedingly rare or absent from the fossil record due to …

NEOICHNOLOGY OF BATS: MORPHOLOGICAL, ECOLOGICAL, AND PHYLOGENETIC INFLUENCES ON TERRESTRIAL BEHAVIOR AND TRACKMAKING ABILITY WITHIN THE CHIROPTERA
Among living mammals, bats (Chiroptera) are second only to rodents in total number of species with over 1100 currently known. Extant bat species occupy many trophic niches and feeding habits, including frugivores (fruit eaters), insectivores (insect eaters), nectarivores (nectar and pollen-eaters), …
