Formation and preservation of vertebrate tracks in semi‐liquid sediments: Insights from tidal flats and laboratory experiments

open access: yesSedimentology, Volume 72, Issue 1, Page 5-33, January 2025.
ABSTRACT Despite the valuable palaeoecological and palaeoenvironmental information provided by vertebrate tracks, those made in semi‐liquid sediments have been largely overlooked because they are assumed to be preserved as a mass of disrupted sediment and to have a low preservation potential.

Estratigrafía de Sr y evolución sedimentaria de los depósitos marinos del Mioceno temprano en el antepaís del norte de la Cuenca Austral (o Magallanes), Argentina [PDF]

open access: yes, 2015
Early Miocene shallow marine deposits in the region of Lago Posadas-Meseta Belgrano (Argentina) represent part of the “Patagoniense” transgression, an Atlantic marine incursion that flooded large part of Patagonia, including the Austral (foreland) Basin (

Rhodolith Beds in a Shifting World: A Palaeontological Perspective

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 34, Issue 11, November 2024.
ABSTRACT The occurrence of rhodolith beds in the stratigraphic record from the Cretaceous to the Pleistocene was analysed from published papers. Most data refer to low–mid latitude records of rhodolith beds described in the Tethyan–Paratethyan–Mediterranean domain. The first putative rhodolith beds are from Albian (uppermost Lower Cretaceous) deposits.

Environmental and climatic proxies for the Cañadón Asfalto and Neuquén basins (Patagonia, Argentina): review of middle to upper jurassic continental and near coastal sequences [PDF]

open access: yes, 2015
In this review, we include several proxies (sedimentology, palynology, invertebrates) from the Cañadón Asfalto and Neuquén basins, to infer the environments and regional climatic context during the Middle to Late Jurassic of Patagonia.

Cryptic Diversity of Mediterranean Neogoniolithon (Corallinales, Corallinophycidae, Rhodophyta)

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 34, Issue 10, October 2024.
ABSTRACT Neogoniolithon is a widespread genus of non‐geniculate coralline algae in the Mediterranean Sea. Three vaguely differentiated species have been reported in the region. This study examined the diversity of Neogoniolithon in the Mediterranean by inferring phylogenies using psbA and COI‐5P markers, applying delimitation algorithms and comparing ...
