An overview of the postcranial osteology of caecilians (Gymnophiona, Lissamphibia)

open access: yesThe Anatomical Record, EarlyView.
Abstract Caecilians comprise a relatively small (~220 species) group (Gymnophiona) of snake‐like or worm‐like, mostly tropical amphibians. Most adult caecilians are fossorial, although some species may live in aquatic or semi‐aquatic environments, either as larvae or adults.

Several occurrences of osteomyelitis in dinosaurs from a site in the Bauru Group, Cretaceous of Southeast Brazil

open access: yesThe Anatomical Record, EarlyView.
Abstract This study investigates the occurrence of osteomyelitis in non‐avian dinosaurs, focusing on the Ibirá locality, a site with a high incidence of this pathological condition. We analyzed six new osteopathic sauropod specimens from the Upper Cretaceous of Brazil.

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

open access: yesThe 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

Histovariability and fossil diagenesis of Pissarrachampsa (Pseudosuchia, Notosuchia, Baurusuchidae) from the Upper Cretaceous of Southeast Brazil

open access: yesThe Anatomical Record, EarlyView.
Abstract Notosuchians were key components of western Gondwanan Cretaceous ecosystems in terrestrial predator niches and exhibited remarkable taxonomic and ecological diversity. Previous research has explored their physiology, metabolism, and histology, revealing varied growth patterns and life history strategies.

Tooth row allometry in domestic rabbits and nondomestic lagomorphs: Evidence for a decoupling of body and tooth row size changes in evolutionary time

open access: yesThe Anatomical Record, EarlyView.
Domestic rabbits of different body sizes differ disproportionately in the length of their tooth row or the length of their diastema. Abstract In various domestic mammals, smaller breeds tend to have proportionally larger teeth, whereas this is not a universal trend across mammals.

Markiana nigripinnis (Perugia, 1891) as a putative member of the subfamily Stevardiinae (Characiformes: Characidae): spermatic evidence

open access: yesNeotropical Ichthyology, 2011
The genus Markiana was until recently recognized as incertae sedis in the family Characidae, even though alternative placements for this genus have been advanced since its original description. More recently, it was hypothesized that Markiana nigripinnis
