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 ...

ABSTRACT Filamentous, anastomosing spar‐filled networks in Phanerozoic carbonates have been interpreted as the mineralised remains of keratose (non‐spiculate) sponges, yet their recognition remains contested because fabrics of broadly similar appearance may arise from microbial, diagenetic or physical processes. This study combines direct fossil–modern

The Social Factors of Fossilization
The notion of fossilization has been one of the most controversial, yet enduring topics in second language acquisition (SLA) theory since its first appearance in Selinker’s 1972 seminal article “Interlanguage.” In the past, work regarding fossilization ...

Diet of bird‐like troodontid dinosaurs: synthesis of a contentious clade
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 ...

The Fossilization of Bone: Organic Components and Water [PDF]
In a recent paper (Cook, 1951) the fossilization of bone was consideredfrom the standpoint of the behavior of the principal components: calcium,phosphate, and carbonate.

Cultural geography of heat: Artistic experiments with heat’s animacies
A sustained, cultural geographical engagement with heat is long overdue. I advance this agenda by engaging with the work of contemporary artists. Artists are responding to uneven conditions of global heating by exploring heat’s animacies: how heat interweaves with the practices and textures of life.

THIS essay proposes a relation between contemporary painting and Manuel DeLanda’s Deleuzian inspired materialist ontology. However, my approach does not negotiate direct relations with contemporary painting, instead seeks to investigate structure-generating processes that are common to both non-human geological ...

Parasites play crucial roles in ecosystem balance yet remain largely excluded from conservation assessments. This paper introduces novel indices for quantifying parasite endemism, conservation status and taxonomic‐weighted diversity, alongside the ZISTA software for automated calculation.

Abstract A subadult Moschognathus whaitsi from the Eastern Cape Province, South Africa, was scanned using synchrotron radiation X‐ray computed tomography (SRXCT). Its subadult state allowed the cranial bones and teeth to be identified and individually reconstructed in 3D.
