Piacenzian mixed carbonate‐siliciclastic succession (‘Macco’ unit) deposited on the passive margin of the Tyrrhenian back‐arc basin. Sedimentation was controlled by syn‐sedimentary tectonics, with NW–SE first‐order faults (3–4 km) creating accommodation space and NE–SW second‐order faults (~0.5 km) influencing facies distribution and growth structures.

Paleogene unconformity development from ~64 to 22 Ma for the Magallanes‐Austral retroarc foreland basin (MAB). Schematic shows (A) MAB foreland subsidence and basin infilling, (B) onset of cooling and basin inversion as subducting plate shallows, (C) continued foreland uplift, erosion and cooling as the oblique Farallon‐Phoenix ridge subducts beneath ...

During the Late Permian, the rise of the Gondwanides Belt trapped marine waters, giving birth to a vast megalake. This lake shifted between overfilled, balanced‐fill and underfilled stages that are recorded by high‐frequency accommodation changes, while meteorological seiches shaped the sedimentary dynamic and produced heterolithic beds.

The role of tetrapod trace fossils in continental ichnofacies models [PDF]
The ichnofacies model provides the main framework to understand the paleoenvironmental significance of trace fossils. Traditionally focused on invertebrate trace fossil, the ichnofacies model has only recently expanded to include tetrapod footprints. The

ABSTRACT In‐depth ichnological and sedimentological analyses of the Cenomanian–Turonian boundary Oceanic Anoxic Event (OAE2) from the Western Interior Seaway of west‐central Alberta reveal a persistent physico‐chemically stressed setting. The interval is characterised by a dominantly diminutive and diminished ichnological assemblage, with familiar ...

Expanding the Ichnofacies Model to Tidal Straits: Testing Predictions and Assessing Anomalies
ABSTRACT Trace fossils are instrumental in facies analysis, but some depositional environments remain underexplored. Cenozoic deposits in Italy have been studied to evaluate the ichnology of tidal straits. These comprise four zones: (1) strait centre, (2) dune‐bedded strait zone, (3) strait end and (4) strait margin.

ICNOLOGIA DE AMBIENTES CONTINENTALES: PROBLEMAS Y PERSPECTIVAS
A wide variety of biogenic structures mainly produced by insects, spiders, crustaceans, gastropods, bivalves, nematomorphs, nematodes and annelids has been reported from modern nonmarine environments.

ABSTRACT Complex stratigraphic arrangements may be generated through lateral facies transitions from the strata of aeolian depositional systems into bordering peritidal deposits. In such scenarios, sedimentary architectural complexity and associated facies heterogeneities are governed by the interplay between autogenic processes inherent to tidal ...
