The stem placental mammal Prokennalestes from the Early Cretaceous of Mongolia
TLDR
Two Prokennalestes species are regarded as different species rather than sexual morphs of the same species based on rigorous phylogenetic analysis including a large set of known stem therian and stem placental taxa. Expand
Early Cretaceous polar biotas of Victoria, southeastern Australia—an overview of research to date
Poropat, S.F., Martin, S.K., Tosolini, A.-M.P., Wagstaff, B.E, Bean, L.B., Kear, B.P., Vickers-Rich, P. & Rich, T.H., May 2018. Early Cretaceous polar biotas of Victoria, southeastern Australia—anExpand
Origin of the Lateral Wall of the Mammalian Skull: Fossils, Monotremes and Therians Revisited
TLDR
To interpret the fundamental differences in the structure and origin of the braincase sidewalls of monotremes, multituberculates, and therians, MicroCT scans of a mammaliaform, Morganucodon, and two non-mammalian cynodonts and Probainognathus were examined. Expand
Multiple hypotheses about two mammalian upper dentitions from the Early Cretaceous of Australia
TLDR
Two enigmatic, poorly preserved specimens of mammalian upper molars have been recovered from the Eric the Red West locality in Victoria, Australia, and one is likely to be a tribosphenic mammal, the other may have a distant relationship to the monotreme or haramyid Kollikodon. Expand
The bone microstructure of polar “hypsilophodontid” dinosaurs from Victoria, Australia
TLDR
In the present study, eighteen tibiae and femora were utilized in the first multi-specimen ontogenetic histological analysis of Australian polar hypsilophodontids, and bone microstructure alone could not distinguish genera within the Flat Rocks sample, or across the two geologically separate localities. Expand
Comparative cranial morphology in living and extinct platypuses: Feeding behavior, electroreception, and loss of teeth
TLDR
It is hypothesize that Ornithorhynchus and the Miocene taxon Obdurodon have different sensory capacities, which may have resulted from differences in foraging behavior or an adaptation to foraging in cloudy water. Expand
The platypus: evolutionary history, biology, and an uncertain future
TLDR
The evolutionary history, genetics, biology, and ecology of this extraordinary mammal is reviewed, and prevailing threats are highlighted to highlight prevailing threats. Expand
Cretaceous fossil reveals a new pattern in mammalian middle ear evolution
TLDR
The findings suggest that the co-evolution of the primary and secondary jaw joints in allotherians was an evolutionary adaptation allowing feeding with unique palinal (longitudinal and backwards) chewing, and the evolution of the allotherian auditory apparatus was probably triggered by the functional requirements of the feeding apparatus. Expand
The evolutionary origin of jaw yaw in mammals
TLDR
It is hypothesized that cladotherian molar morphologies and musculoskeletal jaw anatomies evolved concurrently with increased yaw rotation of the jaw during chewing cycles, which may have been a crucial evolutionary prerequisite for the functionally versatile tribosphenic molar morphology, which underlies the molars of all therians and is retained by many extant clades. Expand
Jaw shape and mechanical advantage are indicative of diet in Mesozoic mammals
TLDR
It is found that these metrics can be used to distinguish dietary groups for most extant mammals, and to infer diet in Mesozoic taxa, and set the basis for future ecomorphological studies. Expand

TLDR
A PAUP 4.0 analysis based on 277 cranial and postcranial characters has corroborated the position of Asfaltomylos as the most basal member of the Australosphenida, and suggests that australosphenidans are independent from boreospenidans. Expand

Comment on "Independent Origins of Middle Ear Bones in Monotremes and Therians" (II)
TLDR
The malleus has been independently freed from the dentary in monotremes and in therians and acknowledge that BEa^ssertions of fundamental differences in development and morphology between monotreme and therian ears are no longer supported and fossils like Teinolophos are the only potential sources of conflict. Expand
The lower jaw of Morganucodon
TLDR
The genus Morganucodon is found in Yunnan, China, in normal (non-karstic) sedimentary deposits of probable Rhaetian age; and in Wales in karstic deposits in the Carboniferous Limestone, which cannot be younger than Sinnemurian or older than Rhaetic. Expand
The evolution of tribospheny and the antiquity of mammalian clades.
TLDR
Cl cladistic evidence is presented for a single origin of tribosphenic molars and Ambondro may be a stem eutherian, making the split between marsupials and placentals at least 167 m.y. old. Expand
A New Species of Docodon (Mammaliaformes: Docodonta) from the Upper Jurassic Morrison Formation and a Reassessment of Selected Craniodental Characters in Basal Mammaliaforms
TLDR
A new species of the basal mammaliaform Docodon is described, represented by three nearly complete dentaries from the Upper Jurassic Morrison Formation of central Colorado, which unambiguously preserve a complete and undistorted angular process that differs conspicuously from the classical interpretation of the holotype of Docodon victor. Expand
Monotremes as Pretribosphenic Mammals
TLDR
An abundance of evidence points to the conclusion that monotremes are phyletically allied with pretribosphenic, rather than with tribosphenia, mammals, and that they appear to be modern representatives of a Mesozoic radiation of pretrib Hospitable mammals centered largely in Gondwana. Expand
Independent Origins of Middle Ear Bones in Monotremes and Therians
TLDR
Evidence that the angular and articular and prearticular bones retained attachment to the lower jaw in a basal monotreme indicates that the definitive mammalian middle ear evolved independently in living monotremes and therians. Expand
New basal eutherian mammal from the Early Cretaceous Jehol biota, Liaoning, China
TLDR
The morphological differences between Acristatherium and Eomaia indicate that eutherians already had a significant degree of generic diversification ca 125 Ma, and place A. yanensis as the most basal eutherian in the selected group. Expand
