An edentulous partial skeleton of a carnivorous mammal from the Uinta Formation (middle Eocene) of Utah is referred to the rare and enigmatic sabre-tooth clade Machaeroidinae primarily on the basis of alveolar patterns and cranial morphology. The newly recognized skeleton includes portions of both girdles, all long bones, and the first known tarsal and phalangeal material of a machaeroidine. The specimen permits a preliminary reconstruction of the locomotor habits of machaeroidines, which… 

Diegoaelurus, a new machaeroidine (Oxyaenidae) from the Santiago Formation (late Uintan) of southern California and the relationships of Machaeroidinae, the oldest group of sabertooth mammals

This work reports a new genus and species of machaeroidine, Diegoaelurus vanvalkenburghae, established on the basis of a nearly complete dentary with most of the dentition from the late Uintan (middle Eocene) portion of the Santiago Formation of southern California.

Eomakhaira molossus, A New Saber-Toothed Sparassodont (Metatheria: Thylacosmilinae) from the Early Oligocene (?Tinguirirican) Cachapoal Locality, Andean Main Range, Chile

The occurrence of Eomakhaira in strata of early Oligocene age from the Chilean Andes demonstrates that the stratigraphic range of thylacosmilines spanned almost 30 million years, far surpassing those of saber-toothed placental lineages.

Identification of a North American species of Propterodon and an Asian Apataelurus increases the similarity of North American Uintan and Asian Irdinmanhan faunas and suggests that there was substantial exchange of carnivorous fauna during the late middle Eocene.

Postcrania and paleobiology of Patriofelis ulta (Mammalia, Oxyaenodonta) of the Bridgerian (lower–middle Eocene) of North America

P. ulta is interpreted, one of the largest carnivores in its ecosystem, as an ambush predator capable of grappling prey with its flexible forearms.

REIDENTIFICATION OF LATE MIDDLE EOCENE “UINTACYON” FROM THE GALISTEO FORMATION (NEW MEXICO, U.S.A.) AS AN EARLY BEARDOG (MAMMALIA, CARNIVORA, AMPHICYONIDAE)

There is no longer a valid occurrence of Uintacyon postdating the Uintan North American Land Mammal Age, adding to the evidence for rapid replacement of ancient carnivoramorphan lineages by early crown-clade carnivorans in the late middle Eocene, across a period of severe climatic fluctuations 42–40 million years ago.

A Transitional Mammalian Carnivore Community from the Paleogene–Neogene Boundary in Northern Kenya

ABSTRACT The Paleogene–Neogene boundary is an important transitional time for the evolution of African fauna. Many taxa that evolved endemically in the Paleogene begin to wane in diversity, while new

The Postcranial Skeleton of Galecyon: Evidence for Morphological and Locomotor Diversity in Early Hyaenodontidae (Mammalia, Hyaenodontida)

Manipulation of the well-preserved bones forming the crurotarsal joint of Galecyon provides evidence that contradicts a previous proposal that Arfia, another Wasatchian hyaenodontid, was capable of hind foot reversal.

Alcidedorbignya inopinata, a basal pantodont (Placentalia, Mammalia) from the early Palaeocene of Bolivia: anatomy, phylogeny and palaeobiology

One of the major aims of this analysis is to test possible close phylogenetic relationships of Alcidedorbignya inopinata with the five orders of South American “ungulates”, and sheds light on the cranial anatomy of placentals from the earliest Paleocene.

Hyainailourine and teratodontine cranial material from the late Eocene of Egypt and the application of parsimony and Bayesian methods to the phylogeny and biogeography of Hyaenodonta (Placentalia, Mammalia)

It is found that Hyaenodonta most likely originated in Europe, rather than Afro-Arabia, and it is proposed that the superfamily Hyainailouroidea be used to describe this relationship.

Early African hyaenodontid mammals and their bearing on the origin of the Creodonta

The identification of Boualitomus and Tinerhodon as the most primitive and earliest known Hyaenodontidae, and the presence of cimolestids in the late Paleocene of Morocco, support an African origin of the family and its order.

New primitive carnivorans (Mammalia) from the Paleocene of western Canada, and their bearing on relationships of the order

It appears that carnivorans and creodonts share no uniquely derived character states of the dentition that might indicate they are sister-groups, and that carnivors are not sister- groups to other eutherian orders.

New postcrania of Deccanolestes from the Late Cretaceous of India and their bearing on the evolutionary and biogeographic history of euarchontan mammals

The tentative identification of Deccanolestes as a basal stem euarchontan suggests that (1) Placentalia began to diversify and Eu archonta originated before the Cretaceous–Tertiary boundary and (2) the Indian subcontinent, Eurasia, and Africa are more likely places of origin for EUarchonta than is North America.

New postcranial bones of the extinct mammalian family Nyctitheriidae (Paleogene, UK): Primitive euarchontans with scansorial locomotion

Functional analysis shows that nyctitheres had mobile shoulder and hip joints, could pronate and supinate the radius, partially invert the foot at the astragalocalcaneal and upper ankle joints using powerful flexor muscles, all indicative of a scansorial lifestyle and allowing headfirst descent on vertical surfaces.

Craniodental and Postcranial Morphology of Indohyaenodon raoi from the Early Eocene of India, and Its Implications for Ecology, Phylogeny, and Biogeography of Hyaenodontid Mammals

The most comprehensive phylogenetic analysis of Hyaenodontidae to date is presented, which corroborates this relationship but finds South Asian hyaenodonids to be the stem of a group that includes most African hyaENodontids.

Further evidence of the African antiquity of hyaenodontid (‘Creodonta’, Mammalia) evolution

The discovery of Lahimia provides direct evidence for the antiquity of the African evolution of the Hyaenodontidae and the Koholiinae, which is representative of an old African endemic lineage, as initially recognized, is characterized by synapomorphies of LahIMia and Boualitomus, and also by a shared original prevallum/postvallid shearing.

Phylogeny of the carnivora: Basal relationships among the carnivoramorphans, and assessment of the position of ‘miacoidea’ relative to carnivora

The results indicate that the split between the Feliformia and Caniformia appears to have taken place more recently than many earlier studies suggested, and basicranial characters are not significantly more useful than dental features and thus do not represent a ‘holy grail’ morphological character system for reconstructing carnivoramorphan phylogeny.
