The Jurassic period is an important stage in early mammalian evolution, as it saw the first diversification of this group, leading to the stem lineages of monotremes and modern therian mammals. However, the fossil record of Jurassic mammals is extremely poor, particularly in the southern continents. Jurassic mammals from Gondwanaland are so far only known from Tanzania and Madagascar, and from trackway evidence from Argentina. Here we report a Jurassic mammal represented by a dentary, which is… Expand

Ancient Mammals of Gondwanan South America
This is a synopsis of what is known of South American mammals from the Mesozoic Era, which begins (according to present information) in the Early Jurassic around 183–174 Ma when a triconodont tooth… Expand
JURASSIC FISHES OF GONDWANA
The Jurassic is an important period for understanding the origin of modern fish faunas, since it saw the first radiation - and in some cases the origin - of most modern groups. In chondrichthyans,… Expand

A Middle Jurassic heterodontosaurid dinosaur from Patagonia and the evolution of heterodontosaurids
TLDR
A new ornithischian dinosaur from the Middle Jurassic Cañadón Asfalto Formation in central Patagonia, Argentina is reported, and derived features of its anatomy indicate that Manidens belongs to Heterodontosauridae, as the sister taxon of HeterODontosaurus and other South African heterodontsaurids.

The tectonic setting of the Caribbean region and the K/T turnover of the South American land-mammal fauna
According to the fossil record, a biotic interchange of land vertebrates ( e.g. booid snakes, dinosaurs and mammals) occurred between the Americas during the Late Cretaceous-Early Palaeocene. The… Expand
Mammals from the Allen Formation, Late Cretaceous, Argentina
Abstract A mammalian fauna from the Late Cretaceous locality of “Cerro Tortuga,” Allen Formation, Rio Negro Province, Argentina, is described here based on a sample, represented by 7 isolated teeth… Expand
The Gondwanan and South American Episodes: Two Major and Unrelated Moments in the History of the South American Mammals
The first steps in the history of South American mammals took place ca. 130 Ma., when the South American plate, still connected to the Antarctic Peninsula, began to drift away from the African-Indian… Expand

Cosmopolitanism among Gondwanan Late Cretaceous mammals
TLDR
The occurrence of a highly specialized and distinctive group of extinct mammals, the Sudamericidae (Gondwanatheria), in the Late Cretaceous of Madagascar and India is reported, which is the first evidence of gondwanatheres outside South America and the first indication of cosmopolitanism among Late CRETaceous Gondwanan mammals.

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.

TLDR
Phylogenetic and morphometric analyses including these newly discovered taxa suggest a different interpretation: that mammals with tribosphenic molars are not monophyletic. Expand
