Tetrapod Ichnofacies: A New Paradigm

Ichnos, 2007
We recognize three fundamental terms in ichnology: (1) ichnoassemblage, which is an assemblage of ichnofossils conceptually equivalent to an assemblage of body fossils; (2) ichnocoenosis, which is a trace fossil assemblage produced by a biological community that can be characterized by morphological criteria; and (3) ichnofacies, which refers to ...

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.

The Ichnofacies Paradigm

Developments in Sedimentology, 2012
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.

The Phycosiphon Ichnofacies and the Rosselia Ichnofacies: Two new ichnofacies for marine deltaic environments

Journal of Sedimentary Research, 2020
ABSTRACT Seilacherian 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 ...

The Case for Archetypal Vertebrate Ichnofacies

Ichnos, 2016
ABSTRACTVertebrate and invertebrate ichnology have different traditions—the ethological and the biotaxonomic—resulting in corresponding ethoichnofacies and biotaxonichnofacies. Archetypal vertebrate ichnofacies are Chelichnus, Grallator, Brontopodus, Batrachichnus, and Characichnos. Ichnofacies are discernable in nonmarine environments.
