Topological and variational modularity: A case study using the pectoral girdle across the Chrosomus eos‐neogaeus hybridization complex

The Anatomical Record, EarlyView.
Abstract Modularity and integration are key developmental properties and have remained central in evo‐devo research because of how they relate to evolvability. While modularity and integration have commonly been assessed with landmark‐based geometric morphometrics (GMM), other methods such as anatomical network analysis (AnNA) are increasingly being ...

Variation in parrot jaw musculature

The Anatomical Record, EarlyView.
Interspecific morphological differences in some superficial jaw muscles of parrots. Abstract Psittaciformes, the order encompassing parrots and their relatives, are highly diverse and generally known for having a strong beaks used for multiple behaviors. The muscles related to the masticatory apparatus should reflect this functional complexity; however,

Inside the head of Crotalus durissus LINNAEUS, 1758 (Serpentes, Viperidae, Crotalinae): Macroscopic description of the brain with ontogenetic insights

The Anatomical Record, EarlyView.
Abstract Neuroanatomy studies in vertebrates have garnered significant attention in recent years, particularly driven by advancements in computerized tomography imaging techniques. Nonetheless, these advancements remain largely constrained to specific vertebrate groups, notably mammals, birds, and fish, leaving studies in reptiles at an incipient stage.

China shares fossil treasures with the world

The Anatomical Record, EarlyView.
Abstract China has been a rich source of fossils for nearly a century, beginning with the discovery of so‐called Peking man (Sinanthropus pekinensis), known today as Homo erectus pekinensis in the mid 1920s. The first Chinese dinosaurs were described in 1929, the sauropod Helopus (now Euhelopus) and the ornithopod Tanius, described by the Swedish ...
