Modelling marsupial mastication: The biomechanical bite model of the Linnaeus's mouse opossum Marmosa murina (Marsupialia, Didelphidae)

Journal of Anatomy, Volume 247, Issue 6, Page 1187-1203, December 2025.
The marsupial masticatory apparatus has rarely been studied until recently, mainly in Australasian species. We therefore reconstructed the maximum bite forces of the South American Linnaeus's mouse opossum Marmosa murina using in vivo bites, specimen dissections, and 3D static equilibrium of the jaw muscles.

How is the third jaw joint in whales different? Diverse modes of articulation between the jaws of whales

Journal of Anatomy, Volume 247, Issue 6, Page 1224-1240, December 2025.
This study conducts the first comprehensive morphological investigation of the mandibular symphysis in whales. Using gross anatomical observation and CT cross‐sectional data, we describe diverse joint morphologies across 74 extant and fossil cetacean taxa. Toothed whales exhibit unfused, partially fused, or fully fused symphyses.

Who was the real sabertooth predator: Thylacosmilus or Thylacoleo?

The Anatomical Record, Volume 308, Issue 11, Page 2896-2912, November 2025.
Abstract Sabertoothed mammalian predators, all now extinct, were almost exclusively feloid carnivorans (Eutheria, Placentalia): here a couple of extinct metatherian predators are considered in comparison with the placental sabertooths. Thylacosmilus (the “marsupial sabertooth”) and Thylacoleo (the “marsupial lion”) were both relatively large (puma ...

Hypercanines: Not just for sabertooths

The Anatomical Record, Volume 308, Issue 11, Page 2831-2842, November 2025.
Abstract Hypercanines are here defined as hypertrophied caniniform teeth, that is, canine teeth that are elongated to serve specific functions in different clades of mammals and their synapsid ancestors. This article presents an overview of the occurrence of hypercanines, their growth, and their function across a broad range of clades.

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 ...
