,“Triconodonts”,tuse) triangle. This is not a natural group, but some of the smaller clades are, for example, Eutriconodonta and Amphilestheria. “Triconodonts” were abundant in Laurasian landmasses during the Jurassic and to a lesser degree during the Cretaceous. In contrast, the South American fossil record is sca

This exceptional material is crucial in shaping our knowledge of early stem therians and high-level mammalian phylogeny. . retains a relatively primitive braincase, similar to what is expected for the last common ancestor of all mammals, and a

Allotheria: Gondwanatherians and Multituberculates,construct their phylogenetic affiliation. They are generally perceived as sharing a closer ancestor with multituberculates than with therians in a variably conceived Allotheria. Two major groups are classically recognized among the South American Gondwanatheria: the brachyodont-toothed Ferugliotheri

The South American Mesozoic Record and Early Evolution of Mammals,which can be further extended to about 160 Ma, including the post-K/Pg evidence. We review here the distribution, predicted time of origin, and likely place of origin for the lineages covered in the preceding chapters during that span of time and against the evolving geological backdrop of continent

The Cretaceous diversity of meridiolestidans has been grossly overestimated, with taxa based on different dental positions of what was later determinied to be a single taxon.

The South American Mesozoic Record and Early Evolution of Mammals,ntological research in South America, early mammals, in particular, are highlighted. We recognize that we are still in the early stages of development and that much of what we know about Mesozoic South American mammals is likely to be drastically altered by finds in the continent or underrepresented
