Osteology Supports a Stem-Galliform Affinity for the Giant Extinct Flightless Bird Sylviornis neocaledoniae (Sylviornithidae, Galloanseres)

open access: yesPLoS ONE, 2016
The giant flightless bird Sylviornis neocaledoniae (Aves: Sylviornithidae) existed on La Grande Terre and Ile des Pins, New Caledonia, until the late Holocene when it went extinct shortly after human arrival on these islands.

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

open access: yesThe 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 ...

The evolution of an “owl‐like” auditory system in harriers: Anatomical evidence

open access: yesJournal of Anatomy, Volume 247, Issue 5, Page 970-980, November 2025.
Harriers hunt relying on sound, with an accuracy to localize sound sources comparable with owls. To assess whether they have owl‐like auditory specializations, we analyzed brain and skull structures using histology and microCT scans. Harriers possess an enlarged external acoustic meatus and significantly expanded auditory brainstem nuclei, up to 12 ...

The Role of GPR39 in Regulating Osteoblast Function, Bone Matrix Quality, and Gender‐Specific Bone Homeostasis

open access: yesJournal of Cellular Physiology, Volume 240, Issue 10, October 2025.
ABSTRACT GPR39, a zinc‐sensing receptor, is essential for bone homeostasis in male mice through regulation of osteoblast function and matrix composition. This study examined the effects of GPR39 deficiency in female mice using both global and osteoblast lineage‐specific GPR39 knockout models (Gpr39Ob−/Ob−).
