Palaeogeography, Palaeoclimatology, Palaeoecology, 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.

ABSTRACTSeilacherian Ichnofacies have been established, to date, for characterizing relatively stable depositional settings. Environments characterized by temporally and spatially varying physico-chemical stresses, however, have languished and been described ichnologically in the context of their “departures” from the archetypal expressions of ...

Environmental factors affecting the development of the Zoophycos ichnofacies in the Lower Cretaceous Río Mayer Formation (Austral Basin, Patagonia) [PDF]
Palaeogeography, Palaeoclimatology, Palaeoecology, 2015 The Río Mayer Formation (Berriasian-Albian) is part of the basal infill of the Austral Basin, southwestern Gondwana. In the Los Glaciares National Park (Santa Cruz Province) seven sections were sedimentologically studied in detail.

Departures from the archetypal deltaic ichnofacies
Geological Society, London, Special Publications, 2022Abstract Recent work has focused on erecting new Seilacherian ichnofacies for depositional environments subject to recurring temporal and spatial variations in physico-chemical stress. In marine deltaic settings, these correspond to the Phycosiphon Ichnofacies for mudstone-dominated prodeltaic deposits and

Abstract Three fundamental terms in ichnology are: (1) assemblage, which is equivalent to an assemblage of body fossils; (2) ichnocoenosis, which is a trace fossil assemblage produced by a biological community

Abstract The ichnofacies paradigm has evolved over a six-decade period since its original inception by Dolf Seilacher. It is a multidimensional framework underpinned by recurring, facies-controlled groupings of biogenic structures that reflect animal responses to paleoenvironmental conditions.

Ichnofacies: a mixture of taphofacies and biofacies
Lethaia, 1991The environmental significance of individual ichnofacies has become a point of debate, and the Scoyenia ichnofacies is not clearly defined. Removal of the marine/non-marine boundary from ichnofacies definitions, as well as the bathymetry control, would render the Scoyenia ichnofacies unnecessary and would consolidate the definitions of the remaining ...

Ichnofacies and bathymetry: a passive relationship
Journal of Paleontology, 1990Ichnofacies stand today as one of the more elegant but widely misunderstood concepts in ichnology, especially where paleobathymetry is concerned. Marine ichnofacies arenotintended to be paleobathometers, as some workers continue to imply (e.g., Lockley et al., 1987; Ekdale, 1988); rather, they are archetypical facies models based upon recurring ...

The Paleoenvironmental Significance of the Nearshore Curvolithus Ichnofacies
PALAIOS, 1987Newly discovered Curvolithus-rich trace-fossil assemblages in fan-delta deposits of the Pennsylvanian Minturn Formation of Colorado are remarkably similar to several other Carboniferous deltaic ichnofaunas, as well as those from Jurassic fan-delta environments and other marginal-marine deposits with freshwater influence.
