Exposed weapons: A revised reconstruction of the facial anatomy and life appearance of the saber‐toothed cat Megantereon (Felidae, Machairodontinae)

The Anatomical Record, Volume 308, Issue 11, Page 2924-2943, November 2025.
Abstract Megantereon was a widespread saber‐toothed felid from the Pliocene and Pleistocene of the Old World and North America, but its rarity in the fossil record makes it complicated to restore its life appearance. Lack of complete specimens makes it necessary to combine information from fossils of different individuals to reconstruct their facial ...

Diversity of Anaplasma and Ehrlichia/Neoehrlichia Agents in Terrestrial Wild Carnivores Worldwide: Implications for Human and Domestic Animal Health and Wildlife Conservation

Frontiers in Veterinary Science, 2018
Recently, the incidence and awareness of tick-borne diseases in humans and animals have increased due to several factors, which in association favor the chances of contact among wild animals and their ectoparasites, domestic animals and humans.

Covariation in the Craniocervical Junction of Carnivora

Journal of Morphology, Volume 285, Issue 11, November 2024.
The craniocervical junction in mammals is a biomechanically unique region that involves the occiput and two specialized vertebrae: the ring‐shaped atlas (CV1) and the axis (CV2) with its peculiar odontoid process (Dens). In Carnivora, the present study indicates that quantitative variation in CV1 morphology reflects a functional signal, while CV2 ...

The primitive giant panda Kretzoiarctos beatrix (Carnivora, Ursidae) from the hominid locality of Hammerschmiede: dietary implications

Papers in Palaeontology, Volume 10, Issue 5, September/October 2024.
Abstract Extant giant pandas are among the most herbivorous forms of the order Carnivora, feeding mainly on hard plant material. The first steps of their evolutionary lineage are of particular interest for our understanding of the factors that led to this specialized niche.

Mutation pressure mediates a pattern of substitution rates with latitude and climate in carnivores

Ecology and Evolution, Volume 14, Issue 8, August 2024.
This study revealed a robust correlation between substitution rates and latitudinal gradients, rather than adaptation‐related parameters. And the results suggest that nonadaptive forces (mutation pressure) have a more widespread impact on mitochondrial genes compared to adaptive forces. Abstract The evolutionary patterns of the mitochondrial genome are

Morphological disparity of mammalian limb bones throughout the Cenozoic: the role of biotic and abiotic factors

Palaeontology, Volume 67, Issue 4, July/August 2024.
Abstract Mammals exhibit ecology‐related diversity in long bone morphology, revealing an ample spectrum of adaptations both within and between clades. Their occupation of unique ecological niches in postcranial morphology is thought to have occurred at different chronological phases in relation to abiotic factors such as climate and biotic interactions

Updates to the caniform fauna (Carnivora, Caniformia) of the John Day Formation, Oregon, USA

Journal of Paleontology
Abstract The John Day Formation of central Oregon preserves a diversity of Oligo-Miocene caniform carnivorans, many of which were first described from the formation. However, many historically important specimens lack detailed locality or stratigraphic information, complicating any analysis of faunal change ...

The evolutionary and ecological convergence of the raccoon and raccoon dog: A perfect storm of invasive species in Europe 浣熊与貉的进化与生态趋同:欧洲入侵物种的完美风暴

Wildlife Letters, Volume 2, Issue 2, Page 67-72, June 2024.
A novel examination of the evolutionary convergence of body shape in the raccoon (Procyon lotor) and raccoon dog (Nyctereutes procyonoides) is provided. Their ecological convergence as invasive species in Europe is reviewed. Problems that have arisen from these introductions are described, and prospects for their management are considered.

Reinterpretation of tuberculate cervical vertebrae of Eocene birds as an exceptional anti‐predator adaptation against the mammalian craniocervical killing bite

Journal of Anatomy, Volume 244, Issue 3, Page 402-410, March 2024.
We report avian cervical vertebrae from the late Eocene Phosphorites du Quercy in France that are densely covered with tubercles. Micro‐computed tomography shows these fossils to have a remarkably thick cortex and dense interior. We hypothesize that this unique vertebral morphology served to strengthen the cervical column in the upper part of the neck ...
