The Anatomical Record, EarlyView.Abstract Pterosaur dental biology remains poorly understood despite its importance for comprehending feeding strategies and flight adaptations. Here, we present the first comprehensive histological analysis of an ornithocheiriform pterosaur tooth from the Lower Cretaceous Crato Formation (Santana Group, Northeast Brazil).

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 ...

An osteohistological analysis of Triceratops (Ornithischia: Ceratopsidae) cranial ornamentation
The Anatomical Record, EarlyView.Abstract Ceratopsids are among the most distinctive and well known extinct Cretaceous vertebrates, yet many details regarding the growth and composition of their cranial features are still not fully anatomically described or understood. In particular, striking cranial adornments such as the postorbital horns and parietal‐squamosal frill of Triceratops ...

The Anatomical Record, EarlyView.Abstract An ultrastructural morphometric analysis of the postnatal development of the lung in the gray short‐tailed opossum (Monodelphis domestica) has been conducted to evaluate the morphofunctional status of this poorly developed marsupial lung immediately following parturition.

The Anatomical Record, EarlyView.Abstract Studies investigating paleopathologies in sauropods remain scarce despite their relative abundance in the fossil record. In this study we report new occurrence of paleopathological features, corresponding to a neoplasm found in a middle caudal vertebra (MCT.R.2120) of an advanced titanosaur from the Presidente Prudente Formation (Bauru Basin ...

The Anatomical Record, EarlyView.Abstract Prozostrodon brasiliensis, a probainognathian cynodont of the clade Prozostrodontia, is recognized as a key taxon for understanding the origin of Mammaliaformes and mammals. Despite detailed investigations of its cranial anatomy, the postcranial skeleton has received comparatively less attention.

The Anatomical Record, EarlyView.Abstract Hyperodapedontine rhynchosaurs possessed a unique oral apparatus, long interpreted as an adaptation for processing abrasive and resistant plant material. However, the microanatomical and histological evidence supporting this interpretation remains poorly documented.

The Anatomical Record, EarlyView.Abstract The organization and function of reptilian excurrent ducts remain poorly characterized, particularly in Neotropical snakes. We provide the first integrative morphological, histochemical, immunohistochemical, and ultrastructural analysis of the proximal post‐testicular ducts of Crotalus durissus across reproductive stages.

One‐Pot Synthesis of a Small Synthetic Ligand for Antibody Purification
Biotechnology and Bioengineering, EarlyView.One‐pot liquid‐phase synthesis of the synthetic ligand B1Al2A2 enables controllable ligand density and efficient capture of IgG and IgY with high recovery and purity, streamlining small‐ligand affinity purification workflows. ABSTRACT The development of synthetic affinity ligands offers a cost‐effective alternative to traditional biological ligands ...

BMEMat, EarlyView.Mitochondria‐endoplasmic reticulum contact sites (MERCS) are areas where the mitochondria and endoplasmic reticulum closely interact. In this study, we utilize synthetic organelle glues to artificially engineer MERCS for regulating cardiomyocyte development, through which the immature and chemo‐plasticity issues of undifferentiated cells are addressed.
