The Trouble with Ichnofacies

open access: yesGeosciences
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 ichnofacies and ichnoassemblages in terrestrial deposits of China [PDF]

open access: yesJournal of Palaeogeography, 2014
Over the last 30 years, terrestrial ichnofossil research was mostly focused on three ichnofacies: the Scoyenia ichnofacies, characterizing transitional fluvio-lacustrine environments, the Mermia ichnofacies, characterizing fully lacustrine settings, and ...

Ichnofacies and Facies Interpretation

open access: yesPALAIOS, 1993
The use of archetypal ichnofacies in facies interpretation is criticized because it does not provide the resolution that can be obtained by using traditional methods of paleoecological analysis: analyzing the autecology and then moving to the synecology (including the ichnofabric) and ...

Integrated Ichnofacies models for deserts: Recurrent patterns and megatrends [PDF]

open access: yesEarth-Science Reviews, 2016
Abstract Although it is commonly assumed that the trace-fossil record of eolian dunes and associated environments is invariably poor, a systematic review of the available information indicates that this is not necessarily the case. A model involving five main phases of colonization of desert environments through the Phanerozoic is proposed in this ...

Ichnological discrimination of hemipelagic‐dominated slope versus basin‐floor mudstones: Insights from early Viséan successions of a distally steepened ramp, northern Iran

open access: yesThe Depositional Record
Integrating sedimentological and ichnological data from the uppermost unit of the Mobarak Formation (early Viséan, Northern Iran), deposited in a distally steepened ramp, provides insights into deep‐water muddy gravity flows in mud‐rich slope settings ...

Firmground ichnofacies recording high-frequency marine flooding events (Langhian transgression, Vallés-Penedés Basin, Spain) [PDF]

open access: yesGeologica Acta, 2005
The decapod burrow Spongeliomorpha sudolica occurs associated with transgressive firmgrounds in the transition between Aragonian continental red beds and Langhian marine units in some of the inner sectors of the Vallès-Penedès Basin.

Use of Lithofacies and Ichnofacies in Interpreting the Nise Formation

open access: yes, 2020
Niseformasjonen ble avsatt på den midt-norske kontinentalsokkelen fra Santon til Campan. Niseformasjonens avsetningsmiljø har lenge vært preget av ulike tolkninger, som har plassert formasjonen fra “åpen sjø” til dypere bassenggulv. Tolkningene varierer selv om de samme geologiske strukturene har blitt betraktet.

THE LATE CRETACEOUS VERTEBRATE ICHNOFACIES OF BOLIVIA - FACTS AND IMPLICATIONS

open access: yesPublicación Electrónica de la Asociación Paleontológica Argentina, 2015
Cretaceous dinosaur tracks are known in Central Bolivia since 1968. Recent work shows that tracksites are widespread and occur in multiple layers from the Campanian to the Late Maastrichtian.
