Redescription of the Triassic cynodont Cistecynodon parvus and reassessment of its phylogeny

open access: yesThe Anatomical Record, EarlyView.
Abstract Cynodontia is an important subclade of Therapsida that first occurred in the late Permian. It includes extinct subclades which are the non‐mammaliaform cynodonts and Mammaliaformes, with the latter ultimately giving rise to crown mammals. The systematics of non‐mammaliaform cynodonts has been extensively studied and is relatively well‐resolved,

Evolutionary radiation of large‐bodied gorgonopsians from the lower Abrahamskraal formation of South Africa

open access: yesThe Anatomical Record, EarlyView.
Abstract The middle Permian represents a critical interval in therapsid evolution, when gorgonopsians emerged as some of the first specialized apex predators within terrestrial ecosystems. Despite their significance, the early diversification of Gorgonopsia in Gondwana remains poorly understood due to scarcity and fragmentary material.

Widespread distribution of large silesaurids evidenced by a new record from the Middle Triassic of southwest Gondwana

open access: yesThe Anatomical Record, EarlyView.
The largest silesaurid known from South America is described here, demonstrating that silesaurids reached large body sizes in southwestern Gondwana. This discovery further underscores the widespread geographic distribution and temporal persistence of large silesaurids across Pangea, despite faunal turnovers and environmental events such as the Carnian ...

Quantitative muscle architecture in large carnivorous marsupials (Marsupialia: Dasyuridae) and links to substrate use and prey processing

open access: yesThe Anatomical Record, EarlyView.
Abstract The Dasyurid species Sarcophilus harrisii, Dasyurus maculatus, and Dasyurus viverrinus, occupying diverse ecological niches and forming a guild structure in Tasmania, provide a basis for examining the roles of various forelimb muscle groups in prey capture and locomotion.

Systemic Hormonal Contraceptive Use Is Associated With Greater Odds of Rotator Cuff Tears, Shoulder Instability, Dislocation, and Other Shoulder Pathologies: A Propensity Matched Epidemiological Study

open access: yesArthroscopy, EarlyView.
Purpose To evaluate whether systemic estrogen‐only, progestin‐only, or combined hormonal contraceptives (HCs) are associated with increased risk of shoulder pathologies in reproductive‐age females. Methods A retrospective cohort study of female patients presenting to clinic from 2013 to 2020 and aged 13‐50 with 5 years of follow‐up was conducted using ...

Trends and Current Situation of China's Meat Sector

open access: yesAnimal Research and One Health, EarlyView.
ABSTRACT As the world's largest meat producer, consumer, and importer, China's meat sector has undergone profound transformation over the past decade, driven by biological crises (e.g., African Swine Fever), environmental policies, and global market integration. This study analyzes the sector's production restructuring, consumption diversification, and
