Molecular and morphological baraminology of Xenarthra

open access: yes, 2023
There are 31 xenarthran species living today, made up of armadillos, anteaters, and sloths. These animals are characterized by a narrow, elongated skull and a unique vertebral process in the posterior trunk. Xenarthra represents an apobaramin within which several holobaramins may be discerned, using both mitochondrial DNA and morphological data.

Turbinal bones are still one of the last frontiers of the tetrapod skull: hypotheses, challenges and perspectives

open access: yesBiological Reviews, Volume 99, Issue 6, Page 2304-2337, December 2024.
ABSTRACT Turbinals are bony or cartilaginous structures that are present in the nasal cavity of most tetrapods. They are involved in key functions such as olfaction, heat, and moisture conservation, as well as protection of the respiratory tract. Despite recent studies that challenged long‐standing hypotheses about their physiological and genomic ...

The gross reproductive morphology of the male Temminck's pangolin Smutsia temminckii (Smuts, 1832)

open access: yesAnatomia, Histologia, Embryologia, Volume 53, Issue 4, July 2024.
Abstract The Temminck's pangolin (Smutsia temminckii) is one of eight pangolin species worldwide and the only pangolin present in southern Africa. Historically, pangolins have not been able to reproduce successfully in captivity and this may be in part due to the lack of knowledge and understanding with regards to the pangolin reproductive system ...

Morphological disparity of mammalian limb bones throughout the Cenozoic: the role of biotic and abiotic factors

open access: yesPalaeontology, Volume 67, Issue 4, July/August 2024.
Abstract Mammals exhibit ecology‐related diversity in long bone morphology, revealing an ample spectrum of adaptations both within and between clades. Their occupation of unique ecological niches in postcranial morphology is thought to have occurred at different chronological phases in relation to abiotic factors such as climate and biotic interactions

slc26a12—A novel member of the slc26 family, is located in tandem with slc26a2 in coelacanths, amphibians, reptiles, and birds

open access: yesPhysiological Reports, Volume 12, Issue 11, June 2024.
Abstract Solute carrier family 26 (Slc26) is a family of anion exchangers with 11 members in mammals (named Slc26a1‐a11). Here, we identified a novel member of the slc26 family, slc26a12, located in tandem with slc26a2 in the genomes of several vertebrate lineages.

The virtual brain endocast of Incamys bolivianus: insight from the neurosensory system into the adaptive radiation of South American rodents

open access: yesPapers in Palaeontology, Volume 10, Issue 3, May/June 2024.
Abstract Caviomorph rodents are endemic to South America and are one of the most adaptively diverse radiations of rodents today. Although their origin and diversification have been intensively studied, questions still remain about many of the details of where, when and how the group radiated.
