  journal={Journal of Morphology},
Functional analysis of the limb bones of the erethizontid Steiromys duplicatus, one of the most abundant Miocene porcupines from Patagonia, provides evidence to infer their locomotor behavior. Remains of the giant Neosteiromys pattoni (Late Miocene of Northeast Argentina) are also analyzed. Osteological and myological features of extant porcupines were evaluated and used as a model to interpret the functional significance of Miocene species' limbs. Several features in erethizontids are… 
Postcranial Morphology of the Extinct Rodent Neoepiblema (Rodentia: Chinchilloidea): Insights Into the Paleobiology of Neoepiblemids
The analyzed postcranial features of Neoepiblema are consistent with the limb morphology of ambulatory rodents, but with faculty to dig or swim.
Paleobiology of Argyrolagus (Marsupialia, Argyrolagidae): an astonishing case of bipedalism among South American mammals
It is concluded that Argyrolagus had bipedal jumping locomotion as well as good capacity to dig, constituting an astonishing case of convergence with the small bipedAL rodents and small Australian macropodids.
The tarsal‐metatarsal complex of caviomorph rodents: Anatomy and functional‐adaptive analysis
The morphological disparity recognized in this study seems to result from specific locomotor adaptations to climb, dig, run, jump and swim, as well as phylogenetic effects within and among the groups studies.
Muscular Reconstruction and Functional Morphology of the Forelimb of Early Miocene Sloths (Xenarthra, Folivora) of Patagonia
The reconstructed forelimb musculature was very well developed and resembles that of extant Pilosa (especially anteaters), although retaining the basic muscular configuration of generalized mammals, and provide support for proposed Santacrucian sloths as good climbing mammals, possibly arboreal or semiarboreal, being also capable diggers.
Postcranial Skeleton of the Miocene Marsupial Palaeothentes (Paucituberculata, Palaeothentidae): Paleobiology and Phylogeny
The results indicate that Palaeothentes would have been an agile cursorial dweller, with leaping ability, similar to the extant paucituberculatan Caenolestes fuliginosus and the didelphid Metachirus nudicaudatus.
Postcranial Skeleton of Glironia venusta (Didelphimorphia, Didelphidae, Caluromyinae): Description and Functional Morphology
The skeletal morphology of G. venusta and the high variation existent in further neotropical marsupials with a variety of body sizes, reveal a diverse combination of features associated to specialized capacities of movements, indicating a diversity of locomotory modes and postures in didelphids.
Anatomy of the hindlimb musculature in the cursorial caviomorph Dasyprocta azarae Lichtenstein, 1823 (Rodentia, Dasyproctidae): functional and evolutionary significance
The musculature of the hindlimb of the cursorial caviomorph Dasyprocta azarae is described and functionally evaluated, together with osteological associated traits, and several features are indicative of emphasized parasagittal movements and stabilized joints.
Muscular reconstruction and functional morphology of the hind limb of santacrucian (Early Miocene) sloths (Xenarthra, Folivora) of Patagonia
Functional features of the hind limb of Santacrucian sloths are supported, together with those of the forelimb, that are congruent with climbing behavior, and support the hypothesis that Santac Trucilian sloths were good but slow climbing mammals.
Functional Anatomy of the Forelimb of Plesiotypotherium achirense (Mammalia, Notoungulata, Mesotheriidae) and Evolutionary Insights at the Family Level
Muscular reconstruction and functional properties of the forelimb of Plesiotypotherium achirense are infer and there are only slight differences among the comparison sample, except for Mesotherium cristatum, which reflect significant osteological modifications, likely to help increasing the moment arm while scratch-digging.
Postnatal ontogeny of limb proportions and functional indices in the subterranean rodent Ctenomys talarum (Rodentia: Ctenomyidae)
It is found that in C. talarum some scratch‐digging adaptations are already present during early postnatal ontogeny, which suggests that they are prenatally shaped, and other traits develop progressively.


Functional‐adaptive anatomy of the forelimb in the didelphidae, and the paleobiology of the paleocene marsupials Mayulestes ferox and Pucadelphys andinus
An attempt to determine the locomotor activities of Mayulestes ferox and Pucadelphys andinus from the early Paleocene site of Tiupampa (Bolivia) is presented and features of the postcranial skeleton, indicative of arboreal adaptations, are found in the extinct marsupials.
The functional anatomy of the forelimb of some african viverridae (Carnivora)
The functional morphology of the forelimbs of the following African Viverridae was studied and the osteology of all the species and the myology of three species is described.

The Tiupampa fossils were therefore more agile than most living didelphids and resembled the condition observed in living dasyurids more, complementing a previous study performed on the forelimb of these fossils.
Limb proportions and adaptations in caviomorph rodents (Rodentia: Caviomorpha)
Morphometric and biomechanical studies were performed to test the relationship between adaptation and morphology of the bones of the proximal and middle limb segments in terrestrial caviomorph rodents and found a functional sequence which seems to reflect an increase in force and muscular development in middle segments of the fore limb.
Functional morphology of the forelimb of Tupaiids (Mammalia, Scandentia) and its phylogenetic implications
Compared to the forelimb character states of tupaiines, those of Ptilocercus are more similar to those of other archontans and it is proposed that the attributes of theForelimb of PtILocERCus are primitive for the Tupaiidae.
Hip structure and locomotion in ambulatory and cursorial carnivores
Cineradiographic analysis of the posture and movements of the femur and pelvis in representatives of three carnivore families reveals discrete locomotor patterns during walking and the habits of certain fossil carnivores are interpreted on the basis of these patterns.
Functional morphology and palaeobiology of the pliocene rodent Actenomys (Caviomorpha: Octodontidae): the evolution to a subterranean mode of life
Based upon the stratigraphic and sedimentological analysis of the palaeosoils containing its fossil remains, it is suggested that Actenomys lived in an environment of moderate to hig primary productivity, which has relevant implications for burrowing cost.

Major stages in the structural and functional evolution of the mammalian humero-ulnar joint are described on the basis of paleontological and cineradiograhic evidence to demonstrate the relationship of diverse types of mammalian humerus joints to limb posture and excursion characteristics.
Model-based analysis of postcranial osteology of marsupials from the Palaeocene of Itaboraí (Brazil) and the phylogenetics and biogeography of Metatheria
Over 130 specimens of metatherian bones from the Palaeocene Itaborai fissures of Brazil are described and analyzed from a functional-adaptive perspective, in order to understand the adaptations of species they represent, obtain taxonomic properties of the species taxa they represent; and estimate their phylogeny within the Metatheria.
