Sedimentology, EarlyView.ABSTRACT Previous studies have documented genetic divergence within the last few million years between northern and southern populations of terrestrial plants and animals along the Baja California peninsula, with many studies hypothesising that the divergence is due to an ancient seaway that crossed the central peninsula and created a physical barrier ...

The Anatomical Record, Volume 309, Issue 9, Page 2424-2441, September 2026.Abstract With the development of dental microwear texture analysis (DMTA), there has been an increasing application of DMTA for dietary estimation in extant and fossil reptiles, including dinosaurs. While numerous feeding experiments exist for herbivorous mammals, knowledge remains limited for carnivorous reptiles. This study aimed to qualitatively and

Diet of bird‐like troodontid dinosaurs: synthesis of a contentious clade
Biological Reviews, Volume 101, Issue 4, Page 1760-1778, August 2026.ABSTRACT Troodontidae is a clade of small‐to medium‐sized maniraptoran theropods that mainly lived in Laurasia (modern Asia, North America and Europe) during the Jurassic and Cretaceous periods and are believed to have had a variety of diets. The uniqueness of troodontid teeth suggests that they diverged from the typical flesh‐based diet of non‐avian ...

New Phytologist, Volume 251, Issue 4, Page 2266-2283, August 2026.Morphospace position and phylogenetic placements of Trimeriantha monopolyada. Summary Floral structure is a key aspect of angiosperm diversity. Recent research revealed that significant floral disparity was already present in the Cretaceous. However, our understanding of early floral diversity remains limited, as it is directly dependent on the fossil ...

Sedimentology, Volume 73, Issue 5, Page 1722-1749, August 2026.ABSTRACT Deciphering sediment provenance is essential to understand depositional patterns and dynamics. This question is particularly important in archaeological contexts to constrain the sedimentological history of unearthed material—an information critically needed, for example, to estimate the age of the deposits—or to apprehend sediment movement ...

International Journal of Osteoarchaeology, Volume 36, Issue 4, Page 908-924, July/August 2026.ABSTRACT A significant methodological difficulty in the interpretation of Pleistocene zooarchaeological assemblages is the identification of taphonomic agents that modify and break bones. Carnivores, in particular, have been a main focus, as competition with carnivores may have affected carcass acquisition opportunities for humans in the past.

Presence of vertebrate coprolites from the Alagoas Basin, Lower Cretaceous [PDF]
Boletim do Museu Paraense Emílio Goeldi. Ciências Naturais, 2010 Coprolites collected from sedimentary rocks of the Maceió Formation, Alagoas Basin are analyzed for the first time. The specimens consist of two complete coprolites of cylindrical morphology that are preserved in commonly fluidized medium- to coarse ...

Systematic Entomology, Volume 51, Issue 3, July‐September 2026.First formally described Archostemata beetles from the Lower Cretaceous Crato Formation are reported, representing the earliest records of the suborder from western Gondwana. Micro‐computed tomography enabled three‐dimensional reconstruction of partially exposed fossils, revealing previously hidden dorsal and ventral morphological characters relevant ...
