Redescription of †Eobrasilia coutoi (Metatheria: Polydolopimorphia), a unique sclerocarpophagous metatherian from the Palaeogene of South America: Systematic affinities, and paleoecological and evolutionary implications

open access: yesThe Anatomical Record, EarlyView.
Abstract The ‘Palaeogene strata’ of the Itaboraí Basin (upper Paleocene‐lower Eocene), Southeastern Brazil, has preserved 29 genera and almost 50 species of metatherians (about 65% of its mammalian diversity). Among them, Eobrasilia coutoi Simpson, 1947 is the most enigmatic due to its quite fragmentary nature.

Hormonal control and signaling of the testis of the bat Molossus molossus during the processes of testicular maturation, regression, and recrudescence

open access: yesThe Anatomical Record, EarlyView.
Abstract Molossus molossus, a species of neotropical bat belonging to the Molossidae family, has an annual reproductive cycle that includes two peaks of spermatogenic activity, one in April and another in September, and a period of total testicular regression in December.

Morphological plasticity in the dentition of the lungfish Gnathorhiza from the Permian of Brazil: A population‐level geometric morphometric analysis

open access: yesThe Anatomical Record, EarlyView.
Abstract Dental plates are pivotal in the lungfish paleontological record, constituting highly mineralized structures resilient to diagenetic processes. This study provides a detailed description and quantitative shape analysis of 95 newly discovered Gnathorhiza sp. dental plates from the Middle–Late Permian Corumbataí Formation, Brazil.

Taxonomic and anatomical comments on “Traversodon(?) major” von Huene, 1936 (Cynodontia) from the Middle Triassic of Brazil

open access: yesThe Anatomical Record, EarlyView.
Abstract Traversodontids were diverse non‐mammaliaform cynodonts that occupied herbivorous and omnivorous niches during the Middle and Late Triassic. In Brazil, they are particularly well represented in the Santa Maria Supersequence, although the taxonomic status of some historically described taxa remains uncertain.

MiniSdd7‐Derived Cytosine Base Editor Promotes Efficient Multiplex Gene Knockout in Porcine Primary Fibroblasts

open access: yesAnimal Research and One Health, EarlyView.
The miniSdd7‐BE4max‐SpG system enables highly efficient multiplex C‐to‐T base editing of APN, CD163, and MSTN in porcine fibroblasts, providing a robust platform for future development of multiplex gene‐edited livestock. ABSTRACT Efficient multiplex genome editing is essential for improving complex traits in livestock that are governed by multiple ...
