ichnofacies and its multifarious significance: A case study from the Miocene Boka Bil Formation of Manipur, India

Journal of the Palaeontological Society of India, 2023
Bioerosional structures are well preserved in the Miocene Boka Bil Formation, exposed in the Kaiphundai section, Thangjing Hill Range of Manipur, India. Eleven ichnospecies representing the Trypanites Ichnofacies, viz., Entobia cateniformis, E .

The Celliforma ichnofacies in calcareous paleosols: An example from the late Miocene Cerro Azul Formation, La Pampa, Argentina [PDF]

, 2016
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.

Depositional environment, ichnological features and oxygenation of Permian to earliest Triassic marine sediments in central Spitsbergen, Svalbard

Polar Research, 2016
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 ...

The ethological study of Glossifungites ichnofacies in the modern & Miocene Mahakam Delta, Indonesia

, 2018
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.

Middle Miocene Climate Transition as reflected by changes in ichnofacies and palaeosols from Patagonia, Argentina

, 2022
The ichnofacies and palaeosols from the La Pava and Collón Curá formations were studied to shed light on the evolution of terrestrial ecosystems from Patagonia (Argentina) during the Middle Miocene Climate Transition.

The Ordovician strata of the Ennedi Plateau, northeastern Chad (Erdi Basin)

Comptes Rendus. Géoscience, 2023
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.

Bryozoan‐Rich Carbonate Units of the Erfoud Area (SE Morocco) Record Latest Katian to Early Hirnantian Interglacial Intervals

Geological Journal, EarlyView.
In this study, we re‐examine the depositional architecture of the Erfoud limestone in Morocco. Introducing new biostratigraphic constraints from chitinozoan assemblages, we show that Katian to Hirnantian bryozoan‐pelmatozoan meadows reflect flooding events linked to a series of interglacial transgressions known to have occurred immediately prior to the

Ichnology of the Rhätsandstein in the Exter Formation (Triassic), Germany

Geological Journal, EarlyView.
Trace fossils from the Rhätsandstein of southern Germany record repeated colonization of high‐energy shallow‐marine substrates before the Triassic–Jurassic transition. The assemblage reflects environmental and preservational controls on ichnodiversity.

Contourite erosional and depositional features of the Maastrichtian chalk on Jasmund peninsula (Rügen island, NE Germany)

Sedimentology, EarlyView.
ABSTRACT Seismic‐scale features such as deeply incised submarine valleys and mounded drifts together with ichnological features indicative of discontinuous sedimentation and erosional episodes have recently been documented from the Upper Cretaceous chalk in the southern Baltic Sea area.

Alluvial ichnofacies from Upper Triassic red beds in India: Implications for palaeoenvironment and palaeoclimate

, 2022
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.
