Mammals from the Age of Dinosaurs: Origins, Evolution, and Structure
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
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.
Dual origin of tribosphenic mammals
Phylogenetic and morphometric analyses including these newly discovered taxa suggest a different interpretation: that mammals with tribosphenic molars are not monophyletic.
Eutherian mammals from the Early Cretaceous of Mongolia
A collection of eutherian mammals consisting of 39 specimens (teeth and jaw fragments) from the ?Aptian or Albian Khoboor Beds in the Gobi Desert, Mongolia, is described. It contains 3 taxa:…
Phylogeny and Systematics of Multituberculate Mammals
It is concluded that microprismatic enamel made its appearance only once in the Cimolodonta and might have originated from unknown members of the Paracimexomys group with separated molar cusps and smooth enamel.

EVOLUTION OF DENTAL REPLACEMENT IN MAMMALS
Abstract We provide a review of dental replacement features in stem clades of mammals and an hypothetical outline for the evolution of replacement frequency, mode, and sequence in early mammalian…

The zalambdalestid skull is more specialized than those of Kennalestes and Asioryctes which occur in the same beds and shows a mosaic of primitive and advanced characters.
