The Anatomical Record, EarlyView.Abstract Actinopterygii is a major extant vertebrate group, but limited data are available for its earliest members. Here we investigate the morphology of Devonian actinopterygians, focusing on the lower jaw. We use X‐ray computed tomography (XCT) to provide comprehensive descriptions of the mandibles of 19 species, which span the whole of the Devonian

The Anatomical Record, EarlyView.Abstract A subadult Moschognathus whaitsi from the Eastern Cape Province, South Africa, was scanned using synchrotron radiation X‐ray computed tomography (SRXCT). Its subadult state allowed the cranial bones and teeth to be identified and individually reconstructed in 3D.

The Anatomical Record, EarlyView.Abstract The Pleistocene is a key period for understanding the evolutionary history and palaeobiogeography of the European rabbit (Oryctolagus cuniculus). The species was first documented in southeastern Iberia at the beginning of the Middle Pleistocene and appears to have rapidly spread throughout Southwestern Europe, where it was found in numerous ...

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).

Dental crown morphological variation and heterodonty in carcharhiniform sharks
The Anatomical Record, EarlyView.Abstract Elasmobranch teeth are highly mineralized structures that constitute the majority of the fossil record for this group. Despite their taxonomic and evolutionary significance, detailed descriptions of dental morphology remain scarce. The order Carcharhiniformes, the most diverse among sharks, comprises 304 valid species that display remarkable ...

In situ biomimetic materials for dentin repair
BMEMat, EarlyView.This review primarily discusses the role and clinical application of key biomimetic materials for in situ dentin repair, providing a feasible foundation for future material and performance optimization in situ dentin regeneration. Abstract Dental defects, ranking among the most prevalent diseases globally, pose a serious threat to human health, with ...

Biological Reviews, EarlyView.ABSTRACT Human life history is derived compared to that of our closest living relatives, the great apes. It has been suggested that these derived traits are causally related to aspects of our ecology, social behaviour and cognitive abilities. However, resolving this requires that we know the evolutionary trajectory of our distinctive pattern of growth,

Enamel apatite crystallinity significantly contributes to mammalian dental adaptations
Scientific Reports, 2018 The monophyodont molar teeth, prismatic enamel and the complexity of enamel microarchitecture are regarded as essential dental apomorphies of mammals.
