Article
Sea turtles are characterized by a wide variety of invertebrate ectoparasites. Few of these ectoparasites leave a permanent indication of their presence on the skeletal remains of their host taxa and thus represent ecological information doomed to be lost in the paleontological record. Some barnacle taxa provide an exception to this, in that they c...

Article
Three ichnotaxa have been established for putative bite marks on fossil bone: Mandaodonites, Heterodontichnites and Nihilichnus. The first of these ichnotaxa was established for a sigmoidal trend of 17 shallow impressions on the dorsal surface and 16 deeper impressions on the ventral surface of a Middle Triassic kannemeyeriid dicynodont femur from...
Article
Low-level drone photogrammetry is a technique that allows for the construction of surface orthomosaics and elevation models. Despite being used for a wide range of geological applications, these types of datasets have not yet been explored from a neoichnological perspective. This study uses three examples of tidal flats from the Bay of Fundy to dem...
Article
The carapace and plastron bones of fossil turtles are often characterized by bone modification features such as pits, grooves, and holes. The significance, origin, and frequency of these features remains unclear because they have not been described from the bones of modern turtles. Taxon-specific description and analyses of defleshed turtle shell i...
Article
Hydrocarbon production from the Lower Triassic Montney Formation in northeastern British Columbia, occurs primarily from unconventional reservoirs consisting predominantly of fine-to coarse-grained siltstone beds. In this area, the lithostratigraphy of the formation is difficult to characterize due to the complexities associated with subtle grain-s...
Article
Phrases incorporating the modifier ‘mark’ (e.g., bite mark, tooth mark, gnaw mark, etc.) have recently come under attack. These phrases are wide-spread in their usage, and are, in fact, appropriate to the original definition of the word mark. Phrases such as bite mark and tooth mark are de rigueur as interpretive terms in the larger scientific comm...
Article
The Kambaniru River valley near the city of Waingapu preserves a thick succession of coarse-grained fluvial-deltaic sediment deposited during the Late Pleistocene. This succession incises through a thick uplifted coral reef terrace succession and records intervals of highly episodic flow events during the last glacial interval. The occurrence of in...

Borings and bite marks on fossil turtle carapaces and plastra from the Miocene Moghra Formation, northern Egypt, are herein described. All fossil turtle material from Moghra exhibits ichnofossils. The positions of invertebrate borings on external surfaces of tortoise and turtle shell material at Moghra are consistent with the activities of ectopara...
Article
The reservoir quality of the Lower Triassic (Induan-Olenekian) Montney Formation of the Puskwaskau Field is assessed from two cored intervals. Four lithofacies are identified in the present study mainly based on detailed sedimentological characteristics. Lithofacies 1 (L-1) is composed of interlaminated bituminous very fine- to medium-grained silts...

Homo erectus is the founding early hominin species of Island Southeast Asia, and reached Java (Indonesia) more than 1.5 million years ago1,2. Twelve H. erectus calvaria (skull caps) and two tibiae (lower leg bones) were discovered from a bone bed located about 20 m above the Solo River at Ngandong (Central Java) between 1931 and 19333,4, and are of...

The end-Triassic mass extinction (ETE) is associated with a rise in CO2 due to eruptions of the Central Atlantic Magmatic Province (CAMP), and had a particularly dramatic effect on the Modern Fauna, so an understanding of the conditions that led to the ETE has relevance to current rising CO2 levels. Here, we report multiple phosphorite deposits in...
Article
The validity of the monotypic ichnogenus Thatchtelithichnus has been called into question due to an inference that it is a bioclaustration. Close analysis of the Thatchtelithichnus holmani holotype reveals that no part of this ichnotaxon involves a bioclaustration, and thus it remains a valid ichnotaxon. Thatchtelithichnus holmani has been observed...
Article
This study focuses on the Lower-Middle Triassic Montney, Sunset Prairie, Doig, and, Halfway formations from the foreland basin of the Canadian Cordillera (Alberta and British Columbia). Based on core and outcrop descriptions, correlation of 400 wells, and, on mineralogical analyses, this study interprets the basin-scale, 3D-stratigraphic architectu...
Article
Biologically mediated fabrics are disturbed sediment by organisms that resemble primary physical structures. In this aquaria-based study, the sand-sifting goby, Valenciennea puellaris, produced biogenic sedimentary structures resembling planar lamina and ripple cross lamina with grain sizes ranging from fine sand to gravel. Valenciennea puellaris m...

The mechanisms underpinning the deposition of fine-grained, organic-rich sediments are still largely debated. Specifically, the impact of the interaction of clay particles with reactive, planktonic cyanobacterial cells to the sedimentary record is under studied. This interaction is a potentially major contributor to shale depositional models. Withi...

Deposition of the Lower Triassic Sulphur Mountain Formation of Western Canada was the product of a dynamic interaction of sedimentary processes and tectonism, resulting in highly heterogeneous successions. The Sulphur Mountain Formation, age equivalent to the subsurface Montney Formation, outcrops in South Central Rocky Mountains, Alberta, Canada a...
Article
The Montney Formation is dominated by fine-grained lithologies, primarily siltstone and very fine-grained sandstone. Regionally pervasive hydrocarbon saturation and a lithological framework that is both relatively easy to drill horizontally, as well as sufficiently brittle to respond satisfactorily to hydraulic fracture programs have rendered this...
Article
Revised lithostratigraphic correlations reveal that the current stratigraphic nomenclature for the Middle Triassic within the subsurface of the Western Canada Sedimentary Basin needs modification. This paper introduces a new formation, the Sunset Prairie Formation, for an interval of interbedded light grey, pervasively bioturbated sandstone and dar...
Article
Deposited immediately following the Montney lowstand turbidites, the moderate porosity and low permeability siltstones of the Montney D1 and D2 horizons are important exploration targets. Eight lithofacies are identified, based on detailed sedimentological and ichnological observations. Deposition took place in the distal offshore to offshore-trans...
Article
Between the Lower Triassic Montney Formation and the Middle Triassic Doig Formation, there is an unconformity-bound interval recently identified as the Sunset Prairie Formation which occurs on a regional scale within eastern British Columbia. The interval is Middle Triassic in age and is characterized by interbedded light grey, pervasively bioturba...
Article
This study presents the first published subsidence analysis during the deposition of the Montney Formation. It was deposited during the Early Triassic (ca. 252.2–245 Ma) in the Western Canadian Sedimentary Basin (WCSB) located along the western margin of the North American craton. Subsidence analyses of six representative wells and two outcrop sect...
Article
The subsurface Montney Formation records deposition through the Lower Triassic interval on the northwestern margin of the North American craton. Various evidence, including stratigraphic architecture, the presence of late Paleozoic and Mesozoic zircons and sediment geochemistry support the contention that the Montney is a product of deposition in a...

Stratigraphic correlation of fine-grained successions is not always straightforward. Complicating factors such as unconformities, structural complexity, subsidence, and especially minimal grain-size variation, make the application of traditional correlation methods to fine-grained successions problematic. Alternatively, the analysis of detailed geo...

Fine-grained sediment deposition is often conceived to happen in still water conditions and to represent slow sedimentation rates. However, it has been increasingly noted that mud sedimentation commonly occurs under high-energy conditions. The macrotidal Petitcodiac River estuary is used as an example to investigate the significance of flocculation...
Article
In this paper we examine quantitative ichnological data of silty-mudstone beds from inclined heterolithic stratification (IHS) in order to understand the spatial and temporal controls affecting bioturbation in IHS. Data collected for this study include bed-scale averaged bioturbation intensity, size-diversity index, and ichnogenera abundances. Thes...
Article
Collecting and analyzing semi-quantitative ichnological parameters such as size-diversity index and bioturbation intensity, can increase the resolution of paleoenvironmental analyses. Specialized software, PyCHNO, was designed to ease, improve, and standardize current ichnological data collection techniques. With PyCHNO, ichnological data derived f...
