The Late Miocene Rifian corridor as a natural laboratory to explore a case of ichnofacies distribution in ancient gateways [PDF]

Scientific Reports, 2021
Oceanic gateways have modulated ocean circulation and have influenced climatic variations throughout the Earth´s history. During the late Miocene (7.8–7.35 Ma), the Atlantic Ocean and the Mediterranean Sea were connected through the Rifian Corridor ...

Multiple exostoses and an osteochondroma in a Pliocene canid from Langebaanweg 'E' Quarry (South Africa). [PDF]

J Anat
Overview of XS of pathological radius. Using anatomical descriptions, CT scanning and bone histology, we investigate several skeletal overgrowths of bone (exostoses) in the skeleton of a jackal‐like canid from the world famous Langebaanweg, a Mio‐Pliocene locality in South Africa.

The puzzling influence of Ophiomorpha (trace fossil) on reservoir porosity: X-ray microtomography analysis

Frontiers in Earth Science, 2022
Bioturbation can influence petrophysical properties (e.g., porosity, permeability) of sedimentary rocks and, in consequence, reservoir quality. The impact can be positive, negative, or neutral, requiring detailed ichnological analysis.

Validating a Target-Enrichment Design for Capturing Uniparental Haplotypes in Ancient Domesticated Animals. [PDF]

Mol Ecol Resour
ABSTRACT In the last three decades, DNA sequencing of ancient animal osteological assemblages has become an important tool complementing standard archaeozoological approaches to reconstruct the history of animal domestication. However, osteological assemblages of key archaeological contexts are not always available or do not necessarily preserve enough

Lizards and amphisbaenians (Reptilia, Squamata) from the middle Eocene of Mazaterón (Soria, Spain). [PDF]

Anat Rec (Hoboken)
Abstract The assemblage of lizards and amphisbaenians (Reptilia, Squamata) from the middle Eocene locality of Mazaterón (Spain) is described. Considering the rather limited material available for the study, the assemblage shows a moderate diversity with eight taxa corresponding to five different families.
