Commentary: The missing sabertooth baculum—At what point might the absence of evidence reasonably be considered evidence of absence?

open access: yesThe Anatomical Record, EarlyView.
Abstract Most carnivorans and all modern felids have ossified bacula; however, no machairodont baculum has ever been identified. This is true despite the many fairly complete skeletons found around the world of several sabertooth taxa. Although the bacula of modern felids are much smaller than those of canoids (even the least weasel's baculum is longer

The “Bear” Essentials: Actualistic Research on Ursus arctos arctos in the Spanish Pyrenees and Its Implications for Paleontology and Archaeology

open access: yesPLoS ONE, 2014
Neotaphonomic studies of large carnivores are used to create models in order to explain the formation of terrestrial vertebrate fossil faunas. The research reported here adds to the growing body of knowledge on the taphonomic consequences of large ...

China shares fossil treasures with the world

open access: yesThe 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 ...

A new genus and species of sabretooth, Oriensmilus liupanensis (Barbourofelinae, Nimravidae, Carnivora), from the middle Miocene of China suggests barbourofelines are nimravids, not felids [PDF]

open access: yes, 2020
Since the early 2000s, a revival of a felid relationship for barbourofeline sabretooths has become popular due to recent discoveries of fragmentary fossils from Africa.

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.
