Description of large, well‐preserved Enchodus specimens from the Bearpaw Formation of Alberta, Canada

The Anatomical Record, EarlyView.
Abstract Fishes of the genus Enchodus were abundant and cosmopolitan in the Late Cretaceous, but are primarily known from isolated remains in Canada. Four well‐preserved fish skulls were recovered in recent years from ammolite mines sampling the Bearpaw Formation of Southern Alberta, and are here referred to Enchodus petrosus Cope, 1874.

Anatomy and variation in the paraphyletic Mosasaurus lemonnieri assemblage from the Craie phosphatée de ciply, Belgium

The Anatomical Record, EarlyView.
Abstract Nineteenth century excavations of the Ciply‐Malogne Phosphatic Chalk Formation in Hainaut, Belgium, yielded over 50 partial mosasaur skeletons, the majority of which were referred to the species Mosasaurus lemonnieri Dollo, 1889. In the years since, this taxon has experienced a complicated taxonomic history, and its exceptional hypodigm has ...

Histological Characterization and Comparative Transcriptomic Analysis of Gonads During Early Sex Differentiation in the Northern Snakehead (Channa argus)

Animal Research and One Health, EarlyView.
This study delineates the early sex differentiation timeline in the northern snakehead (Channa argus). These findings provide a foundation for future sex‐control breeding in this economically important species. ABSTRACT The northern snakehead (Channa argus) is an economically important aquaculture species in China.

Cornwall open pit mine

, 2022
This photo, taken about 1880, indicates the simple pick-and-shovel mining methods employed to extract iron ore from the Cornwall open pit mine at that time. In the 1880s, the mine was operated by the Cornwall Ore Banks [sic] Company.

Deciphering the Palimpsest: Chronological Uncertainty and the Interpretation of Mining Landscapes at Písečný vrch (Czech Republic)

Archaeological Prospection, EarlyView.
ABSTRACT We investigated the Písečný vrch (Czech Republic), a site exploited for quartz mining in both prehistoric times and the 20th century. Due to their morphological similarity across all mining periods, the differentiation between pits with archaeological potential and recent ones is challenging.

Dual Effects of β‐TrCP2 Deletion in Bone Homeostasis: Suppression of Osteoclastogenesis and Enhancement of Osteoblast Activity

Arthritis &Rheumatology, Accepted Article.
Objectives To elucidate role of beta‐transducin repeat‐containing protein 2 (β‐TrCP2) in bone homeostasis for its potential as a therapeutic target for osteoporosis. Methods The role of β‐TrCP2 in bone phenotypes was investigated using systemic β‐TrCP1KO and β‐TrCP2KO mice, along with myeloid‐specific conditional β‐TrCP2KO (β‐TrCP2ΔM) mice.
