Late Early Permian–lowermost Triassic carbonate, siliceous (spiculites) and clastic marine sediments in the Marmierfjellet area (Isfjorden, central Spitsbergen) contain a relatively diverse and abundant trace fossil assemblage providing important ...

For about 60 years, the ichnofacies model has been used to identify trace fossil assemblages associated with sedimentary environments. However, the ichnofacies model faces many problems, including: (1) how ichnofacies are defined; (2) non-environmental ...

The ethological study of Glossifungites ichnofacies in the modern & Miocene Mahakam Delta, Indonesia
The presence of Glossifungites ichnofacies indicate cohesive or more lithified substrate environment. Therefore, the presence of Glossfungites ichnofacies surface does not always related to sequence boundary, but more reasonable as event surface.

Trace fossils are highly sensitive to the hydrodynamic conditions of depositional systems, substrate, and climate and hence yield information about spatio-temporal changes in palaeoenvironment and palaeoclimate.

The Ordovician strata of the Ennedi Plateau, northeastern Chad (Erdi Basin)
In the Ennedi Plateau, northeastern Chad, Cambrian(?)–Ordovician to Carboniferous strata represent one of the most proximal succession of the north-facing Gondwana platform. This study presents preliminary results related to the c.

ABSTRACT Early marine carbonate cements generally form in CaCO3‐supersaturated seawater at the seabed or shallow burial depths, resulting in syn‐sedimentary cemented firmgrounds and hardgrounds. The processes controlling early marine diagenesis are complex, particularly in coastal environments where geochemistry is influenced by different water sources

Unusual occurrence of Cochlichnus in aeolian sandstones: evidence for a stiletto fly larval origin
Abstract Cochlichnus anguineus is an ichnotaxon recognized for its distinctive regular wavy morphology. It is a characteristic trace fossil typically associated with aquatic and marginal aquatic environments. However, in this study we examine its unusual occurrence in the aeolian sandstones of the Botucatu Formation (Lower Cretaceous, Paraná Basin ...

Parasitic gastropod bioerosion trace fossil on Cenomanian oysters from Le Mans, France and its ichnologic and taphonomic context [PDF]
We describe and name Loxolenichnus stellatocinctus Breton and Wisshak igen. et isp. nov., a bioerosion trace fossil on an Upper Cenomanian oyster from Le Mans (France). This trace is attributed here to a parasitic gastropod.

The Variable Impact of Heinrich Events on the Benthic Environment of the Porcupine Abyssal Plain
Abstract Heinrich events (HEs) are Pleistocene climate disturbances caused by massive freshwater discharges from the Laurentide Ice Sheet via the Hudson Strait. They appear in marine sediments as layers of ice‐rafted detritus (IRD) and significantly impact the benthic environment.

The Celliforma ichnofacies in calcareous paleosols: An example from the late Miocene Cerro Azul Formation, La Pampa, Argentina [PDF]
Invertebrate trace fossils from the late Miocene Cerro Azul Formation (La Pampa, Argentina) are described and compared with known paleosol ichnofacies. The formation is a loess succession punctuated by numerous calcareous paleosols.
