ABSTRACT Dinomyidae is a South American caviomorph family that was a very diverse group starting in the Miocene, but is now represented by a single species, Dinomys branickii Peters, 1873. An exclusive feature of dinomyids, not recorded in other mammals, is the presence of accessory articular structures lateral to the occipital condyles, termed paracondyles. In a 1916 study of †Tetrastylus intermedius Rovereto, 1914, an extinct dinomyid from northwestern Argentina, Carlos Ameghino suggested… 

Tracing the Paleobiology of Paedotherium and Tremacyllus (Pachyrukhinae, Notoungulata), the Latest Sciuromorph South American Native Ungulates – Part II: Orbital, Auditory, and Occipito-Cervical Regions

The integrative analysis proposed here and in the accompanying contribution aims to shed light on convergences with extant models, paleobiology, niche partitioning, and external appearance of the latest rodent-like ungulates.

A reassessment of the cranial morphology of Neoepiblema acreensis (Rodentia: Chinchilloidea), a Miocene rodent from South America

The cranial anatomy of this extinct rodent Neoepiblema acreensis is reviewed and shows the presence of fossae on the posterior region of the frontal and parietal bones, and a “W‐shaped” fronto‐parietal suture, which are not present in other analyzed chinchilloids.

Resizing the largest known extinct rodents (Caviomorpha: Dinomyidae, Neoepiblemidae) using occipital condyle width

This work estimates body mass in large, extinct rodents using occipital condyle width (OCW), a strong predictor of body size in mammals, using a dataset that circumvents many of the issues faced by previous studies of species.

Occipital condyle width (OCW) is a highly accurate predictor of body mass in therian mammals

Background Body mass estimation is of paramount importance for paleobiological studies, as body size influences numerous other biological parameters. In mammals, body mass has been traditionally

New genus of giant Dinomyidae (Rodentia: Hystricognathi: Caviomorpha) from the late Miocene of Uruguay

The fossil remains of a new genus and species of a giant rodent, Arazamys castiglionii (Mammalia, Rodentia, Dinomyidae), from Arazatí beach in San José Department, southern Uruguay are described and 2 morphologies for the subfamily Eumegamyinae are described.

Making a giant rodent: cranial anatomy and ontogenetic development in the genus Isostylomys (Mammalia, Hystricognathi, Dinomyidae)

The dental ontogeny of large-sized rodents casts doubt on the validity of the subfamily Gyriabrinae, which may be composed of juveniles of different taxa within other subfamilies of Dinomyidae.

Craniodental Ontogeny of the Pacarana Dinomys branickii Peters 1873 (Rodentia, Hystricognathi, Caviomorpha, Dinomyidae)

Results of the analyses indicate fast growth in the rostrum and palatal length but isometric growth in nasal width, rostral height, and length of the upper diastema and some observed that craniomandibular trends in the ontogeny of D. branickii are reflected in the size of Ctenohystrica taxa.

Estudios sobre la familia Dinomyidae, II. Aportes para una osteología comparada de Dinomys branickii Peters, 1873 (Mammalia: Rodentia)

This is the first description of the postcranial skeleton of D. branickii and it is compared with eight other South American caviomorph rodents belonging to eight different families.

Functional anatomy of the limbs of erethizontidae (Rodentia, Caviomorpha): Indicators of locomotor behavior in Miocene porcupines

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.

Myology of the Head, Neck, and Thoracic Region of the Lesser Grison (Galictis cuja) in Comparison with the Red Panda (Ailurus fulgens) and Other Carnivorans: Phylogenetic and Functional Implications

Key associations between axial myological and osteological features that will prove useful for future studies of carnivorans are revealed, including muscle descriptions, weights, and optimizations.

A preliminary qualitative analysis of the axial skeleton of tupaiids (Mammalia, Scandentia): functional morphology and phylogenetic implications

It is proposed here that the attributes of the thorax of Ptilocercus are primitive for the Tupaiidae, that the ancestral tupaiid was arboreal, that a stable thorax was first evolved in anArboreal ancestral archontan, and that the ancestor of the t upaiine condition is derived.

Notes on the Behaviour and Breeding of Pacaranas (Dinomys branickii) in Captivity

Although several zoos have maintained this species, its breeding in captivity has been recorded only recently and the first gravid female died before parturition, but the most recently-mated female was still alive on 10 January 1971.

Large caviomorph rodent footprints of the Late Oligocene Vinchina Formation, Argentina

Footprints and trackways provide valuable information about trackmaker behaviour, locomotion, spatial and temporal distribution, among others. Here we describe tetradactyl mammalian footprints and
