Body mass and sex estimation from lower carnassial tooth morphometry in the endangered Iberian wolf (Canis lupus signatus): An ecomorphological analysis of sexual size dimorphism

open access: yesThe Anatomical Record, EarlyView.
Abstract The Iberian wolf (Canis lupus signatus) is an endangered subspecies characterized by highly fragmented populations and increasing human–carnivore conflict across the Iberian Peninsula. Although body mass strongly influences predator–prey dynamics and ecological performance, quantitative assessments of sexual size dimorphism (SSD) and body mass

Redescription of the cranial morphology of Amphisbaena braestrupi and Amphisbaena laurenti (Squamata: Amphisbaenidae) from the Pleistocene of Brazil using x‐ray computed tomography

open access: yesThe Anatomical Record, EarlyView.
Abstract Amphisbaenians (Squamata: Amphisbaenidae) are fossorial reptiles with highly specialized cranial morphology, yet their fossil record is frequently limited by fragmentary preservation. This study provides a detailed osteological redescription of the skulls of Amphisbaena braestrupi and Amphisbaena laurenti from the Pleistocene of Lagoa Santa ...

Assessment of intraspecific skull variation in the Campanian baenid turtle Plesiobaena antiqua

open access: yesThe Anatomical Record, EarlyView.
Abstract Baenids are freshwater paracryptodiran turtles with a fossil record ranging from the Early Cretaceous to the Eocene. The baenid Plesiobaena antiqua is the most common turtle in the Campanian (Late Cretaceous) Dinosaur Park Formation in Canada, but the apparent intraspecific variation remains poorly understood.

Regional variability in skull sexual dimorphism: Olive baboons, blue monkeys, and vervets confirm the posterior region of the skull and the snout as opposite extremes of sex differences in Old World monkeys

open access: yesThe Anatomical Record, EarlyView.
Abstract This study, alongside prior work on crab‐eating macaques with O'Higgins, investigates regional variation in skull sexual dimorphism across different species of Old World monkeys. Findings reveal consistent patterns: the posterior skull regions (mandibular vertical ramus, chondrocranium and, possibly, the cranial vault) exhibit lower dimorphism,
