Redescription of †Eobrasilia coutoi (Metatheria: Polydolopimorphia), a unique sclerocarpophagous metatherian from the Palaeogene of South America: Systematic affinities, and paleoecological and evolutionary implications

The Anatomical Record, EarlyView.
Abstract The ‘Palaeogene strata’ of the Itaboraí Basin (upper Paleocene‐lower Eocene), Southeastern Brazil, has preserved 29 genera and almost 50 species of metatherians (about 65% of its mammalian diversity). Among them, Eobrasilia coutoi Simpson, 1947 is the most enigmatic due to its quite fragmentary nature.

Supplementation with Commercial Corn Grain or a Mexican Hybrid Variety (Tlaoli Puma) in Sheep at the End of Gestation and Its Effect on Productive and Behavioral Parameters

Agriculture
Using alternative energy sources for animal feed, such as hybrid corn varieties rather than genetically modified ones, is important. Therefore, the objective of this work was to assess the effects of supplementation at the end of gestation with Mexican ...

Mapping the distribution of Meissner corpuscles throughout the human hand: Sex‐ and age‐dependent variations

The Anatomical Record, EarlyView.
Abstract Meissner corpuscles are rapidly adapting mechanoreceptors involved in tactile discrimination in human glabrous hand skin. Detailed information on their regional distribution and variation across age, sex, and hand side remains limited. This study mapped Meissner corpuscles in 17 phalangeal and palmar regions from 46 individuals (27 male and 19

Morphological plasticity in the dentition of the lungfish Gnathorhiza from the Permian of Brazil: A population‐level geometric morphometric analysis

The Anatomical Record, EarlyView.
Abstract Dental plates are pivotal in the lungfish paleontological record, constituting highly mineralized structures resilient to diagenetic processes. This study provides a detailed description and quantitative shape analysis of 95 newly discovered Gnathorhiza sp. dental plates from the Middle–Late Permian Corumbataí Formation, Brazil.

Bioerosion traces in bones reveal an increase in ethological diversity in the insect exploitation of carcasses in the late Triassic

The Anatomical Record, EarlyView.
Abstract This study presents the first detailed description of bioerosion traces produced by insects in bones from the Santa Cruz Sequence (early Carnian, Santa Maria Supersequence, Brazil). An array of traces is reported, consisting of notches, a tube, trails of grooves attributed to the ichnotaxon Osteocallis mandibulus and ornamented depressions ...

Morphological variation of the conus arteriosus in Chondrichthyes: Implications for ecology and evolution

The Anatomical Record, EarlyView.
Abstract Cartilaginous fish have diverse morphological traits that are essential for understanding their evolutionary history and ecological adaptations. However, the conus arteriosus and its valves, key components of the heart and blood circulation, have been underexplored in phylogenetic and ecomorphological contexts.

Distribution of doublecortin in the developing retina of birds: A comparative analysis

The Anatomical Record, EarlyView.
Abstract The avian retina presents an elegant and highly accessible model for investigating the spatial and temporal dynamics of neurogenesis within the central nervous system. In recent years, the microtubule cytoskeleton has emerged not merely as a structural scaffold, but as a dynamic regulator of the transition of a morphologically homogeneous pool

Multivariate Analysis of Hematological Stress Biomarkers and Welfare Domains in Organic and Intensive Pig Farming in Italy: A Pilot Study

Animal Research and One Health, EarlyView.
Intensive or organic farming systems may expose pigs to management or environmental challenges. Our preliminary results concluded that organic farming might enhance adaptive immune function, showing that improvements in welfare can translate into measurable immunological benefits, based on the correlation between welfare assessment and physiological ...
