Abstract In this study I provide a phylogenetic hypothesis for didelphid Marsupials including a suite of 114 postcranial characters. The postcranial evidence was cladistically analyzed separately and concatenated with a nonmolecular data set previously published (71 cranio-dental-external characters). A combined analysis was done including published IRBP (interphotoreceptor retinoid binding protein, 1158 bp), DMP-1 (dentin matrix protein 1, 1176 bp), and RAG-1 (recombinase-activating gene, 2790… Expand
Phylogenetic Relationships and Classification of Didelphid Marsupials, an Extant Radiation of New World Metatherian Mammals
TLDR
A decade of morphological and molecular research on the phylogenetic relationships of didelphid marsupials (opossums) is summarized, with a completely resolved ingroup phylogeny with high support statistics at most nodes. Expand
Postcranial Skeleton of Glironia venusta (Didelphimorphia, Didelphidae, Caluromyinae): Description and Functional Morphology
TLDR
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.

First phylogenetic analysis of the tribe Phyllotini (Rodentia: Sigmodontinae) combining morphological and molecular data
  • L. Carrizo, S. Catalano
  • Medicine, Biology
  • Cladistics : the international journal of the Willi Hennig Society
  • 2015
TLDR
This is the first combined phylogenetic analysis (morphological and molecular) of phyllotines, which includes the widest taxon and character sampling to date, and retrieved Phyllotini as a monophyletic clade with a composition that matches that obtained in most other recent analyses. Expand
Interplay between postcranial morphology and locomotor types in Neotropical sigmodontine rodents
TLDR
The data suggest that Sigmodontine rats retain an all‐purpose morphology that allows them to use a variety of habitats, particularly important when considering the lack of specialization of sigmodontines for a specific locomotor mode. Expand
Phylogeny and evolution of body mass in didelphid marsupials (Marsupialia: Didelphimorphia: Didelphidae)
TLDR
A fully resolved, highly robust phylogeny of didelphids is recovered that tested and confirmed most previously reported groupings, providing a simultaneous depiction of phylogenetic relationships for 81 % of currently recognized species and all relevant supra-specific clades. Expand
Postcranial anatomy of Riograndia guaibensis (Cynodontia: Ictidosauria)
TLDR
Results confirm that the forelimb posture of non-mammaliaform probainognathians was still similar to that of basal synapsids and differed from the more erect posture and parasagittal function of therians. Expand
Postcranial Skeleton of the Miocene Marsupial Palaeothentes (Paucituberculata, Palaeothentidae): Paleobiology and Phylogeny
TLDR
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. Expand
Postcranial skeleton of Spalacopus cyanus (Rodentia: Octodontidae): description and functional aspects
TLDR

A Nearly Complete Juvenile Skull of the Marsupial Sparassocynus derivatus from the Pliocene of Argentina, the Affinities of “Sparassocynids”, and the Diversification of Opossums (Marsupialia; Didelphimorphia; Didelphidae)
TLDR
It is agreed that the appearance of carnivorously-adapted didelphids in South America during the late Miocene, including sparassocynins, is likely related to a decline in diversity of the sparassodonts at this time, and that the disappearance of these carnivorous- adaptations at the end of the Pliocene may have been due to the arrival of placental carnivorans from North America. Expand
Cranial ontogeny of Caluromys philander (Didelphidae: Caluromyinae): a qualitative and quantitative approach
TLDR
Allometric scaling showed that braincase is relatively small in adulthood, whereas other neurocranial components, particularly the orbit, grew isometrically along its length, suggesting a high degree of conservatism in the skull development of Caluromys and other marsupials. Expand

Model-based analysis of postcranial osteology of marsupials from the Palaeocene of Itaboraí (Brazil) and the phylogenetics and biogeography of Metatheria
TLDR
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. Expand
A morphological analysis of marsupial mammal higher-level phylogenetic relationships
TLDR
Twenty-one marsupial terminal taxa representing all the major radiations of marsupials and 10 outgroups, most of which are exceptionally well-preserved fossils such as Vincelestes, Ukhaatherium, and a few basal metatherian taxa, were investigated, resulting in one most parsimonious tree. Expand
PHYLOGENETIC STUDIES ON DIDELPHID MARSUPIALS II. NONMOLECULAR DATA AND NEW IRBP SEQUENCES: SEPARATE AND COMBINED ANALYSES OF DIDELPHINE RELATIONSHIPS WITH DENSER TAXON SAMPLING
TLDR
A combined (simultaneous) maximum-parsimony analysis of both datasets (nonmolecular + IRBP) produced a consensus topology that closely resembled the results of analyzing IRBP separately, and a new genus is described for “Marmosa” canescens. Expand
Phylogenetic Relationships of Oryzomine Rodents (Muroidea: Sigmodontinae): Separate and Combined Analyses of Morphological and Molecular Data
TLDR
A phylogenetic hypothesis for the tribe Oryzomyini is provided that can be used to understand the diversification and evolution of this group of rodents and to revise the current generic-level classification. Expand

First combined cladistic analysis of marsupial mammal interrelationships.
TLDR
Optimal analyses using direct optimization and those based on the static alignment support the basal positions of peramelians (bandicoots) and Dromiciops ('monito del monte') within Australidelphia, and in all but one case these analyses support a monophyletic Eometatheria, a group consisting of all australidelphians excluding peramelian.

CLADISTIC ANALYSIS OF DASYUROMORPHIAN (MARSUPIALIA) PHYLOGENY USING CRANIAL AND DENTAL CHARACTERS
TLDR
For some groups, notably Dasyuridae and a dasyurid clade inclusive of all modern subfamilies, the synapomorphic nature of some derived features appears to be robust, even where they also are present in some outgroup taxa. Expand

TLDR
Two Santacrucian borhyaenoids, Borhyaena tuberata and Prothylacinus patagonicus, are analyzed from a functional-adaptive perspective, and the analysis shows that the forelimb of Prothyllacinus is modified to provide strength and flexibility for controlled climbing. Expand

TLDR
Two terrestrial clades, vombatiforms and macropodids, differ from the arboreal possums in similar aspects, indicating that carpal diversity might be related to function. Expand
