The Anatomical Record, EarlyView.Abstract A recent debate has emerged between Caspar et al. (2024) and Herculano‐Houzel (2023) on inferring extinct dinosaur cognition by estimating brain neuron counts. While thought‐provoking, the discussion largely overlooks the function of cognition, as well as partly neglects the difficulties involved in estimating neuron numbers, which according ...

Human adaptation and population differentiation in the light of ancient genomes
Nature Communications, 2016 Detecting the targets of positive selection in the human genome is challenging. Here, the authors combine modern and ancient genomes to show that alleles strongly differentiated between Africans and Europeans mediated local adaptation in European ...

The Anatomical Record, EarlyView.A new musculoskeletal reconstruction and revision of the cranio‐mandibular anatomy of the Devonian arthrodire placoderm Dunkleosteus terrelli from a comparative and functional anatomical perspective. Dunkleosteus is a specialized arthrodire with many specializations for feeding on large vertebrates, and many of its features are part of broader ...

The Anatomical Record, EarlyView.Abstract The study of morphological evolution is fundamentally tied to ontogeny, yet studies of these heterochronic processes in the fossil record are rare. Fossils belonging to an ontogenetic series are difficult to assign to an ontogenetic stage due to inconsistent proxies for skeletal ages, challenging to taxonomically assign due to morphological ...

Skeletal pathologies in extant crocodilians as a window into the paleopathology of fossil archosaurs
The Anatomical Record, EarlyView.Abstract Crocodilians, together with birds, are the only extant relatives to many extinct archosaur groups, making them highly important for interpreting paleopathological conditions in a phylogenetic disease bracketing model. Despite this, comprehensive data on osteopathologies in crocodilians remain scarce.

The Anatomical Record, EarlyView.Abstract As habitat salinity markedly differs between the endangered, freshwater‐dwelling Saimaa ringed seal (Pusa saimensis Nordquist, 1899) and the brackish water‐inhabiting Baltic ringed seal (Pusa hispida botnica Gmelin, 1788), we investigated whether this difference has resulted in morphological changes to their kidneys.

The Anatomical Record, EarlyView.Abstract Tyrannosaurus is viewed as a model organism in vertebrate paleontology, with numerous studies analyzing its feeding biomechanics. Nonetheless, the evolution of this feeding performance has been under‐addressed in Tyrannosauroidea, especially in basal tyrannosauroids. Here we used muscle‐force reconstruction and finite element analysis (FEA) to

The Anatomical Record, EarlyView.Abstract Differences in skull and tooth morphology, stomach contents, and estimated bite force between medium‐to‐large sized (≥100 kg) predatory theropod dinosaurs have long been suspected to correlate with differences in their diets and dietary guilds (e.g., hypercarnivory, piscivory).
