The enigmatic mammal Necrolestes patagonensis from the Miocene of Patagonia possesses a highly apomorphic osteological form that has confounded phylogenetic interpretation for over a century. In this time it has been affiliated with both eutherians and metatherians; however, a recent study by Rougier et al. (Proc Natl Acad Sci USA 109:19871–19872, 2012) raises the intriguing possibility that Necrolestes is a relictual member of a clade of South American non-therian dryolestoids, the… Expand

New cladotherian mammal from southern Chile and the evolution of mesungulatid meridiolestidans at the dusk of the Mesozoic era
A new meridiolestidan mammal is described from the Late Cretaceous of southern Chile, based on a partial jaw with five cheek teeth in locis and an isolated upper premolar, and Phylogenetic analysis places Orretherium as the earliest divergence within Mesungulatidae. Expand
Craniomandibular Anatomy of the Subterranean Meridiolestidan Necrolestes patagonensis Ameghino, 1891 (Mammalia, Cladotheria) from the Early Miocene of Patagonia
The most novel discoveries concern specializations of the snout that help identify Necrolestes as a head-lift digger, as are the extant African golden moles and Australian marsupial moles. Expand
Tribosphenic Mammals from the Lower Cretaceous Cloverly Formation of Montana and Wyoming
ABSTRACT We report a diverse assemblage of tribosphenidan mammals from several localities in the Cloverly Formation (Lower Cretaceous, Albian) of Montana and Wyoming. This unit is of historicalExpand
Digging adaptation in insectivorous subterranean eutherians. The enigma of Mesoscalops montanensis unveiled by geometric morphometrics and finite element analysis
Evolutionary convergence analyses reveal that the shape of Mesoscalops montanensis represents a unique morphology in the context of fossorial mammals and that its functional performance, albeit superficially similar to that of extant Chrysochloridae, still represents a nonconvergent optimum for adaptation to digging. Expand
Australohyaena antiqua (Mammalia, Metatheria, Sparassodonta), a large predator from the Late Oligocene of Patagonia
The genus Australohyaena gen. nov is proposed based on a phylogenetic reconstruction that demonstrates that A. antiqua is a Borhyaenidae (Mammalia, Sparassodonta), grouped with Arctodictis and Borhyaena, but not with Pharsophorus lacerans, the genus to which antiqua was formerly assigned. Expand
The Skull of Epidolops ameghinoi from the Early Eocene Itaboraí Fauna, Southeastern Brazil, and the Affinities of the Extinct Marsupialiform Order Polydolopimorphia

It is proposed that Polydolopimorphia as currently recognised is polyphyletic, and that argyrolagids (and possibly other taxa currently included in Argyrolagoidea, such as groeberiids and patagoniids) are members of Paucituberculata. Expand
The evolutionary origin of jaw yaw in mammals
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.

Evolution of the Vertebrate Ear
This chapter introduces some major concepts from the world of paleontology, starting with some of the techniques used to investigate fossils and a basic description of the embryonic origin of skull and braincase anatomy. Expand
Inner ear labyrinth anatomy of monotremes and implications for mammalian inner ear evolution
The inner ear anatomy of two extant monotremes is examined, hypothesizing that the ancestral inner ear of stem mammaliaforms is characterized by a straight or slightly curved osseous cochlear canal, a lagenar macula, lagenAR nerve fibers separated from a larger bundle of cochlea nerve fibers, the presence of an organ of Corti and an intra‐otic co chlear ganglion suspended by membranous connective tissue.

Evolution of the Middle and Inner Ears of Mammaliaforms: The Approach to Mammals
The homoplasies of ear structures in early mammalian evolution, although seemingly complex, are consistent with the new understanding of a labile morphogenesis of mammalian ears under a complex developmental genetic network. Expand


The Miocene mammal Necrolestes demonstrates the survival of a Mesozoic nontherian lineage into the late Cenozoic of South America
It is concluded that Necrolestes is a remnant of the highly endemic Mesozoic fauna of nontribosphenic mammals in SA and is a late-surviving member of the recently recognized nontherian clade Meridiolestida, which is currently known only from SA. Expand
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.

The Osteology and Systematics of the Enigmatic Australian Oligo-Miocene Metatherian Yalkaparidon (Yalkaparidontidae; Yalkaparidontia; ?Australidelphia; Marsupialia)
It is concluded that the ordinal status of Yalkaparidon remains justified based on current evidence, and the two currently recognized species, Y. coheni and Y. jonesi, are maintained, and a revised diagnosis for YalkAParidontia is presented. Expand
Was the Oligo‐Miocene Australian metatherian Yalkaparidon a ‘mammalian woodpecker’?
A qualitative analysis of characters of the skull and dentition of the enigmatic Oligo-Miocene Australian metatherian Yalkaparidon supports the hypothesis that it is probably a fourth ‘mammalian woodpecker’, and discovery of the (as yet unknown) manus of YalkAParidon will test this hypothesis by revealing whether any of its digits are elongate. Expand
The Phylogenetic Affinities of the Enigmatic Mammalian Clade Gondwanatheria
It is hypothesized that the anterior molariforms of sudamericid gondwanatherians evolved from blade-like precursors similar to the p4 of Ferugliotherium, possibly in response to the appearance of grasses in Gondwana during the Cretaceous. Expand
The Pwerte Marnte Marnte Local Fauna: a new vertebrate assemblage of presumed Oligocene age from the Northern Territory of Australia
A newly discovered vertebrate fossil locality near Pwerte Marnte Marnte, southern Northern Territory of Australia, contains representatives of Agamidae (Lacertilia), Crocodylia, Dromornithidae (Aves)Expand
Australia's first fossil marsupial mole (Notoryctemorphia) resolves controversies about their evolution and palaeoenvironmental origins
It is now clear that archaic burrowing marsupial moles were adapted to and probably originated in wet forest palaeoenvironments, preadapting them to movement through drier soils in the xeric environments of Australia that developed during the Neogene. Expand
Neither a Rodent nor a Platypus: a Reexamination of Necrolestes patagonensis Ameghino
On biogeographic and some anatomical grounds, identification of Necrolestes as a metatherian remains a compelling option, however, pending a combined-data phylogenetic analysis encompassing Theria and accounting for the anatomical diversity of Necrology, possible membership in Eutheria should not be ruled out. Expand
A new phylogeny for basal Trechnotheria and Cladotheria and affinities of South American endemic Late Cretaceous mammals
The endemic South American mammals Meridiolestida are found to be non-cladotherian trechnotherians related to spalacotheriid symmetrodontans based on a parsimony analysis of 137 morphological characters among 44 taxa. Expand
