Unfused transverse foramen of the atlas vertebra in the Neandertal lineage fossils
The Anatomical Record, EarlyView.Abstract In anatomically modern humans, the atlas can display an unfused transverse foramen (UTF) but currently the presence of UTF in the Neandertal lineage is uncertain due to a scarcity of prevalence studies and no exhaustive record of its presence throughout the entire hominin fossil record.

Internal framework and geochemistry of the Carboniferous Huaco granite pluton, Sierra de Velasco, NW Argentina [PDF]
, 2018 The A-type Huaco granite pluton of the Velasco range (Sierras Pampeanas of northwest Argentina) is formed by three coeval granitic facies and contains subordinate coeval-to-late facies, as well as enclaves, dikes and stocks that show different temporal ...

Patterns of spinal motion, kinematic spaces and the land‐to‐sea transition in carnivorans
The Anatomical Record, EarlyView.Using 3D reconstructions, we quantify intervertebral joint mobility to investigate how cervical, thoracic, and lumbar vertebral regions evolved distinct kinematic roles in pinnipeds. The findings reveal lineage‐specific adaptations for swimming and highlight the functional significance of vertebral joint flexibility in ecological transitions.

Evidence of Quaternary tectonics along Río Grande valley, southern Malargüe fold and thrust belt, Mendoza, Argentina [PDF]
, 2019 The Malargüe fold and thrust belt is developed in the Argentinian Andes between 34° and 37° S, through the tectonic inversion of Upper Triassic and Lower Jurassic depocenters of the Neuquén Basin, with an uplift history since the Cretaceous.

The Anatomical Record, EarlyView.Osteohistological sampling on different bones of theropod dinosaur documents discrepant age record, growth, and metabolism. This could result unprecise paleobiological inferences if samplings are based on single bones. However, multi‐bone sampling can attenuate these discrepancies, helping to infer growth dynamics and physiology of these extinct ...

The Anatomical Record, EarlyView.Abstract The Upper Cretaceous São José do Rio Preto Formation (Bauru Group, southeastern Brazil) has yielded a fragmentary but taxonomically diverse record of titanosaur sauropods, although elements from cervical series remain scarce. Here, we describe a nearly complete sauropod axis from the Vila Ventura Paleontological Area, representing an uncommon ...
