From alluvial fans to lacustrine systems: trace fossils applied to paleoenvironmental analysis in the Taubaté Basin (Brazil) [PDF]
Brazilian Journal of GeologyStudies integrating ichnology and sedimentology in paleoenvironmental interpretations are rare in Brazilian rift successions. This study applies an integrated ichno-sedimentological analysis to a well core from the Resende and Tremembé Formations ...

Journal of Anatomy, EarlyView.A three‐dimensional biomechanical model of the musculoskeletal system is used to analyse the potential locomotor functions of the small (~1 kg) Late Triassic archosaurian reptile Gracilisuchus stipanicicorum. The study finds that, potentially like the ancestral archosaur, this taxon was probably quadrupedal, plantigrade and neither strongly sprawling ...

Sedimentology, EarlyView.ABSTRACT This research examines the spatial and geochemical interactions between mat‐forming microorganisms and thalassinid shrimp in an intertidal flat situated on the shores of Willapa Bay, Washington, USA. The study serves as a contemporary analog for the relationships between mats and burrowing organisms in deep time.

Basin Research, Volume 38, Issue 3, May–June 2026.2D seismic and well data reveal multi‐phase basin filling in the Whatcom Sub‐Basin shaped by syn‐depositional tectonism. An Eocene transition from forearc basin to forearc depression corresponds to decreasing normal‐fault density and throw, both upsection and eastward. Paleogene–Neogene strata are the best CO2 storage targets.
