Morphological variation in atlas and axis of Neotropical spiny rats (Rodentia, Echimyidae)

The Anatomical Record, EarlyView.
Abstract The unique morphologies of the first two cervical vertebrae, the atlas and axis, represent a significant innovation in mammalian evolution. These structures support the weight of the head and enable intricate movements of the head and neck.

Unravelling the phylogeny of armadillos and their kin (Mammalia, Xenarthra, Cingulata) combining morphological, molecular, and stratigraphic data

Cladistics, EarlyView.
Abstract Cingulata, a major lineage of Xenarthra, comprises extinct and extant armoured placental mammals that diversified throughout the Cenozoic. Despite extensive study, phylogenetic hypotheses based on morphological and molecular data remain incongruent, and no total evidence analysis has been conducted. Here, we integrate the largest morphological

Early history of mammals is elucidated with the ENCODE multiple species sequencing data. [PDF]

PLoS Genetics, 2007
Understanding the early evolution of placental mammals is one of the most challenging issues in mammalian phylogeny. Here, we addressed this question by using the sequence data of the ENCODE consortium, which include 1% of mammalian genomes in 18 species

Hoffmann's two‐toed sloth II: Muscle architectural properties in the thoracic limb of Choloepus (Pilosa: Xenarthra)

Journal of Anatomy, EarlyView.
Two‐toed sloths use their thoracic limbs for more frequent and greater suspensory support than three‐toed sloths and have muscle architectural properties consistent with stability of the pectoral girdle, enhanced flexor force/torque applied at the shoulder and elbow joints, and grip on the support as indicated by their myology. Abstract Two‐toed sloths
