Functional anatomy, jaw mechanisms, and feeding behavior of Dunkleosteus terrelli (Placodermi, Arthrodira)

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 coelurosaur theropods of the Romualdo formation, early Cretaceous (Aptian) of Brazil: Santanaraptor placidus meets Mirischia asymmetrica

The Anatomical Record, EarlyView.
Abstract The upper carbonate concretion levels of the Romualdo Formation (Aptian, Brazil) have yielded several theropod dinosaur remains, including spinosaurids and the coelurosaurs Santanaraptor placidus and Mirischia asymmetrica, the phylogenetic affinities of which are controversial.

Multi‐method analysis for the three‐dimensional reconstruction of muscle fascicles from DiceCT datasets

The Anatomical Record, EarlyView.
Abstract Muscle architecture is a major determinant of muscle performance and, in mammalian lineages, has been correlated with both feeding ecology and locomotor behaviors. Over the past decade, contrast‐enhanced micro‐CT (DiceCT) has emerged as an alternative to traditional dissection‐based measurement.

Gonadal development in scorpion mud‐turtles, Kinosternon scorpioides, in a controlled environment

The Anatomical Record, EarlyView.
Stage 20 was identified as the critical point for gonadal differentiation in Kinosternon scorpioides, providing key insights into sex determination. These findings enhance conservation strategies by supporting reproductive management and population viability in both in situ and ex situ programs. Abstract Research on gonadal development including sexual

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 ...

Nasal soft‐tissue anatomy of Triceratops and other horned dinosaurs

The Anatomical Record, EarlyView.
Abstract Although ceratopsid dinosaurs possess a characteristically hypertrophied narial region, soft‐tissue anatomy associated with such a skeletal structure and their biological significance remain poorly understood. The present study provides the first comprehensive hypothesis on the soft‐tissue anatomy in the ceratopsid rostrum based on the Extant ...
