Unusual occurrence of Cochlichnus in aeolian sandstones: evidence for a stiletto fly larval origin
Abstract Cochlichnus anguineus is an ichnotaxon recognized for its distinctive regular wavy morphology. It is a characteristic trace fossil typically associated with aquatic and marginal aquatic environments. However, in this study we examine its unusual occurrence in the aeolian sandstones of the Botucatu Formation (Lower Cretaceous, Paraná Basin ...

Abstract Planktonic foraminifera are instrumental in reconstructing paleoceanographic and paleoclimatic conditions. However, preferential dissolution can significantly bias both assemblages and chemical analyses, leading to biased interpretations. Bioerosional drill holes are commonly found in foraminiferal tests; however, it remains unknown if these ...

The ecological distribution of some species of Foraminifera living in estuaries can be used in the interpretation of former coastal lines. There is a close relationship between tide level and the distribution of particular benthic foraminifer species.

Biome Specialisation in Squirrels: Phylogenetic and Geographic Patterns
ABSTRACT Aim Habitat breadth shapes species' responses to environmental change and influences large‐scale biodiversity patterns. According to Vrba's resource‐use hypothesis, biome specialists (inhabiting a single biome) exhibit higher speciation rates than generalists due to increased population isolation during habitat fragmentation, generally ...

Descripcion de Eoglobigerina Ferreri, un nuevo foraminifero planctonico del Paleoceno
Se describe una nueva especie de foraminífero planctónico del Paleoceno medio, encontrada en diferentes lugares de la Cuenca Vasco-Cantábrica, aunque su distribución geográfica en aquel tiempo fue mucho más amplia, como lo atestigua el hecho de que ...

“Like We're Meeting the Ancestors”: Toward an Lˈnucentric Archaeology in Miˈkmaˈki
ABSTRACT We explore the possibilities for an archaeology that is relevant to, and empowering of, Indigenous futures by reflecting on four seasons of archaeological fieldwork, our encounters with Lˈnu (or Miˈkmaw) material culture, our experiences returning to ancestral Lˈnu places, and our engagements with sociocultural and archaeological ...
