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.

Silesaurid (Archosauria: Dinosauriformes) remains from the base of the Dockum Group (Late Triassic: Otischalkian) of Texas provide new insights to the North American record of dinosauriforms

The Anatomical Record, EarlyView.
Abstract Silesaurids (Archosauria: Dinosauriformes) are found in Middle to Upper Triassic deposits across Pangea, but few stratigraphic sections record the evolution of the group in one geographic area over millions of years. Here, we describe silesaurid remains from the oldest of the Upper Triassic stratigraphic sequence from the base of the Dockum ...

The lower jaw of Devonian ray‐finned fishes (Actinopterygii): Anatomy, relationships, and functional morphology

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

Estimation and rapid identification of later stages during embryonic development of the oviparous lizard Sceloporus aeneus (Squamata: Phrynosomatidae)

The Anatomical Record, EarlyView.
Abstract Stages of embryonic development for reptiles have been presented in tables that may include all or part of embryonic development. When oviposition occurs in some lizards, embryos are already in the later stages of development; likewise, the size of the eggs increases as incubation time progresses.
