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
Crocodylian diversity peak and extinction in the late Cenozoic of the northern Neotropics.
TLDR
A diversity peak in sympatric occurrence of at least seven species is shown, based on detailed stratigraphic sequence sampling and correlation, involving four geological formations from the middle Miocene to the Pliocene, and on the discovery of two new species and a new occurrence. Expand
Homeotic effects, somitogenesis and the evolution of vertebral numbers in recent and fossil amniotes
TLDR
It is shown that the mammalian (synapsid) and reptilian lineages show early in their evolutionary histories clear divergences in axial developmental plasticity, in terms of both regionalization and meristic change, with basal synapsids sharing the conserved axial configuration of crown mammals, and basal reptiles demonstrating the plasticity of extant taxa.

A comprehensive morphological analysis of talpid moles (Mammalia) phylogenetic relationships
TLDR
It is most parsimonious to infer one migration from Eurasia to North America and two back‐migrations to Eurasia, and it is ambiguous if Talpini and Scalopini evolved their full fossorial habits independently or not. 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.

Vestibular labyrinth diversity in diprotodontian marsupial mammals
TLDR
There has been a change both in size and in relative arrangement of the semicircular canals that for some aspects maps onto the ecological change from arboreality to terrestriality, and Dendrolagus shows features typical of terrestrial species in spite of its arboreal lifestyle. Expand
Neogene vertebrates from Urumaco, Falcón State, Venezuela: Diversity and significance
TLDR
Several freshwater species, including Serrasalminae fish, thorny catfishes, silver croaker, redtail catfishing, matamata turtle, river dolphin and probable sirenians, are consistent with the hypothesis that a tributary and/or delta of the Orinoco existed in this area of north‐western Venezuela during late Miocene times. Expand
Mammalian skull heterochrony reveals modular evolution and a link between cranial development and brain size
TLDR
It is argued that cranial heterochrony in mammals has occurred in concert with encephalization but within a conserved modular organization. Expand
Species inflation and taxonomic artefacts—A critical comment on recent trends in mammalian classification
TLDR
This work highlights several cases of splitting and argues that much of this taxonomic inflation is artificial due to shortcomings of the phylogenetic species concept and unjustified reliance on insufficient morphological and/or genetic data. Expand
