New Early Cretaceous Geosites with Palaeogeographical Value from the Northwestern Caucasus

Heritage, 2022
Field investigations in the northwestern segment of the Greater Caucasus, a Late Cenozoic orogen, have permitted the establishment of two new geosites, namely the Ubin and Bezeps geosites.

Facies and trace fossils of the Upper Cretaceous Sillakudi Formation (Cauvery Basin, S. India) and their palaeoenvironmental significance

Journal of the Palaeontological Society of India, 2023
The Sillakudi Formation is a sandstone-dominated succession bounded by unconformities. It represents the oldest unit of the Ariyalur Group deposited during the Campanian under fully established passive margin depositional conditions. The present study is

Middle Jurassic Zoophycos and Chondrites from the Mélah Formation of Saharan Atlas, Algeria [PDF]

Estonian Journal of Earth Sciences, 2019
The ichnogenera Zoophycos and Chondrites are described for the first time from the Middle Jurassic of Algeria. The trace fossil assemblage recovered from the Mélah Formation contains seven ichnospecies (Chondrites targionii, C.

Anomuran and brachyuran trackways and resting trace from the Pliocene of Valduggia (Piedmont, NW Italy): environmental, behavioural, and taphonomic implications

Natural History Sciences, 2016
We report a rich ichnofacies including trackways and a resting trace made by indeterminate anomuran and brachyuran crabs, and other organic sedimentary structures produced by invertebrates.

Stratigraphic and sedimentological aspects of ichnofabric analysis

Известия высших учебных заведений: Геология и разведка, 2015
Trace fossils are one of the paleontological groups that could be used for solving complex geological problems. Trace fossils represent the sedimentological structures, produced by living organisms in the mass of sediment.

Sabellid tubes from the deep shelf off Liguria (Italy): A modern analogue for distal Skolithos Ichnofacies?

, 2023
Dense associations of vertical trace fossils are typically used as a proxy for nearshore palaeoenvironments. Here we challenge this assumption by reporting dense associations of vertical tubes occupying vast areas of the deep shelf off Liguria (Italy) at

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 .
