A new occurrence of tetrapod footprints from the Late Triassic of the Candelária Sequence, Brazil

open access: yesThe Anatomical Record, EarlyView.
Abstract The Hyperodapedon Assemblage Zone of the Candelária Sequence (Santa Maria Supersequence, Paraná Basin) preserves one of the most significant Late Triassic continental vertebrate assemblages in southern Brazil. Despite the relatively well‐documented body fossil record from this interval, ichnological records remain comparatively scarce.

Application of shallow seismic profiling to study riverbed architectural facies: a case study of the Tocantins river (Pará - Brazil)

open access: yesAnais da Academia Brasileira de Ciências, 2012
To date, the vast majority of river sedimentology study has relied on two main categories of observation: direct observation of shallow trenches, cut faces and cores or geophysical survey on dry and shallow regions of braid bars.

Testing the Dry Refuge Model: Paleoecological Insights From Late Pleistocene Gomphotheres in Ecuador

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
We present paleontological evidence that may prove the Dry Refuge Model in Ecuador during the Late Pleistocene. ABSTRACT Paleoenvironmental records indicate that Neotropical regions near the Equator experienced reduced rainfall during the Last Glacial Maximum (LGM). However, some records show conflicting environmental signals.

Predatory behaviour on Ostracoda: spatial analysis of drill‐hole distribution in relation to shell size and ornamentation

open access: yesPalaeontology, Volume 69, Issue 4, July/August 2026.
Abstract Palaeobiological evidence of predation on ostracods derives primarily from drill‐hole traces. However, this record is limited to sparse reports and rare quantitative analyses hinder understanding of influence of predator–prey interaction in the evolution of ostracods. Moreover, predation is rarely studied in deep‐water settings.

A Reserve of Light: Photography, Ethnography, and Lucid Memory in Contemporary Chile

open access: yesThe Journal of Latin American and Caribbean Anthropology, Volume 31, Issue 2, June 2026.
ABSTRACT This article takes shape as a shared inquiry between an ethnographer and a photographer, in continuity with the photographic archive of Luis Poirot. Through sustained encounters with his images and archival practices, the text does not position itself outside the archive that motivates it, but unfolds from within it.

Development of Holocene lacustrine microbialites on the Iberian Peninsula: Insights into environmental and depositional controls using X‐ray CT and petrography

open access: yesSedimentology, Volume 73, Issue 4, Page 1148-1184, June 2026.
ABSTRACT Microbial mats and microbialites are common in modern and ancient saline lacustrine environments and are highly responsive to biological and environmental factors. As such, they represent important sources of high‐resolution environmental data across a wide range of geological time. Nonetheless, interpretation of fossil mats is non‐trivial due

A Formação Serra Alta, Permiano, no centro-leste do Estado de São Paulo, Bacia do Paraná, Brasil

open access: yesBrazilian Journal of Geology
A individualização e o mapeamento da Formação Serra Alta no Estado de São Paulo sempre foi motivo de controvérsia na comunidade geológica. Apesar de apresentar extensão comparável à Formação Irati em subsuperfície, a unidade ainda carece de estudos mais ...
