Mammals from the Age of Dinosaurs: Origins, Evolution, and Structure
TLDR
The Mesozoic Mammals in Space and Time and the Interrelationships of Mesozoics Mammals are studied to understand the distribution and relationships of these animals.
In quest for a phylogeny of Mesozoic mammals
TLDR
A phylogeny of all major groups of Mesozoic mammals based on phylogenetic analyses of 46 taxa and 275 osteological and dental characters, using parsimony methods is proposed, suggesting that the “obtuse−angle symmetrodonts” are paraphyletic, and that they lack reliable and unambiguous synapomorphies.
The Phylogeny of the Native South American Ungulates
Dual origin of tribosphenic mammals
TLDR
Phylogenetic and morphometric analyses including these newly discovered taxa suggest a different interpretation: that mammals with tribosphenic molars are not monophyletic.

Eutherian tarsals from the late Paleocene of Brazil. American Museum novitates ; no. 2761
Disassociated eutherian proximal tarsals (astragalus, calcaneum) from Riochican (late Paleocene) fissure fills near Sao Jose de Itaborai, Rio de Janeiro, Brazil, are described and, where feasible,…
High-precision 40Ar/39Ar geochronology and the advent of North America's Late Cretaceous terrestrial fauna.
A densely sampled, diverse new fauna from the uppermost Cedar Mountain Formation, Utah, indicates that the basic pattern of faunal composition for the Late Cretaceous of North America was already…
The Campanian Terlingua local fauna, with a summary of other vertebrates from the Aguja Formation, Trans-Pecos Texas
ABSTRACT The Terlingua local fauna is a rich assemblage of predominantly terrestrial micro vertebrates from the Upper Cretaceous Aguja Formation of Trans-Pecos Texas. Marine invertebrates (which…
Magnetic Polarity Stratigraphy and Mammalian Fauna of the Deseadan (Late Oligocene-Early Miocene) Salla Beds of Northern Bolivia
The Salla Beds contain a rich assemblage of Deseadan mammals that traditionally has been considered of early Oligocene age. These deposits, located 90-100 km SE of La Paz, Bolivia, consist of more…
