ABSTRACT We report the discovery of the earliest European carnivoraforms, based on two new taxa from the latest Paleocene of France and Romania. A new species of Vassacyon, V. prieuri, from the locality of Rivecourt (MP6b; Oise, France) (MP = Mammalian Paleogene reference levels) is described based on a dentary fragment and isolated teeth. This species displays several primitive features compared with species of Vassacyon known from the early Eocene of North America and Europe. A second… 
Whence the beardogs? Reappraisal of the Middle to Late Eocene ‘Miacis’ from Texas, USA, and the origin of Amphicyonidae (Mammalia, Carnivora)
Re-examination of previously described specimens and their inclusion in a cladistic analysis revealed the two peculiar carnivoraforms from the Chambers Tuff of Trans-Pecos, Texas to be diminutive basal amphicyonids; as such, they are assigned to new genera Gustafsonia and Angelarctocyon, respectively.
The oldest Cenozoic mammal fauna of Europe: implication of the Hainin reference fauna for mammalian evolution and dispersals during the Paleocene
The mammal fauna of Hainin is particularly interesting as the oldest in the Cenozoic of Europe, and the earliest reference level of the mammalian biochronological scale for the European Palaeogene, and an analysis of the fauna as a whole (relative abundance and species richness) is presented.
The European Mesonychid Mammals: Phylogeny, Ecology, Biogeography, and Biochronology
It seems that the mesonychids went through two radiative events: the first during the Paleocene, the second mostly during the early Eocene, while the latter resulted in the appearance of the most specialized mesONYchids, such as Pachyaena and Mesonyx.
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.
Evolution of plesiadapid mammals (Eutheria, Euarchonta, Plesiadapiformes) in Europe across the Paleocene/Eocene boundary: implications for phylogeny, biochronology and scenarios of dispersal
Comparisons between plesiadapids from Europe and North America indicate a separation from at least the terminal Tiffanian, suggesting correlation of the European reference level MP6 with the North American biozones Ti-5b and Ti-6.
The first potential fossil record of a dibamid reptile (Squamata: Dibamidae): a new taxon from the early Oligocene of Central Mongolia

The dentary of Hoeckosaurus exhibits some characters of the two extant dibamid taxa, however, the open Meckel’s groove, together with other characters, show that this group was morphologically much more diverse in the past.
Digital endocasts from two late Eocene carnivores shed light on the evolution of the brain at the origin of Carnivora
X‐ray computed tomography is used to create digital endocasts of two early carnivores, Quercygale angustidens and Gustafsonia cognita, to better understand the processes driving the evolution of the brain in this group.
Evolutionary history of Carnivora (Mammalia, Laurasiatheria) inferred from mitochondrial genomes
The complete mitochondrial genomes were analysed to reconstruct the phylogenetic relationships and to estimate divergence times among species of Carnivora, leading to a robust resolution of suprafamilial and intrafamilial relationships.
Molecular identification of the trematode P. ichunensis stat. n. from lungs of siberian tigers justified reappraisal of Paragonimus westermani species complex
A partial reappraisal of Paragonimus westermani species complex is performed, confirming the taxonomic status as valid species for P. ichunensis stat.


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 carnivoraforms from the early Eocene of Europe and their bearing on the evolution of the Carnivoraformes
The discovery of a new species of Quercygale, which is generally considered as the closest carnivoraform to the crown‐group Carnivora, shows that the genus had already lost the M3 by the early Eocene and supports an important, but very poorly known, radiation of the carnivoraforms at least during the earliestEarly Eocene.
A New Basal Caniform (Mammalia: Carnivora) from the Middle Eocene of North America and Remarks on the Phylogeny of Early Carnivorans
Lycophocyon hutchisoni illuminates the morphological evolution of early caniforms leading to the origin of crown-group canoids and suggests that loss of the upper third molars and development of well-ossified entotympanics that are firmly fused to the basicranium are not associated with theorigin of the Carnivora as traditionally thought, but instead occurred independently in the Caniformia and the Feliformia.
New proviverrines (Hyaenodontida) from the early Eocene of Europe; phylogeny and ecological evolution of the Proviverrinae
It is indicated that the Proviverrinae diversified greatly during the Early Eocene Climatic Optimum and show a general trend towards specialization throughout the Eocene.
Early Eocene Leptictida, Pantolesta, Creodonta, Carnivora, and Mesonychidae (Mammalia) from the Eureka Sound Group, Ellesmere Island, Nunavut
We describe the leptictid Prodiacodon; the pantolestids Palaeosinopa sp.nov., cf. Palaeosinopa, and Pantolestidae, gen. et sp. indet.; the creodonts Palaeonictis and Prolimnocyon; the carnivorans
New mammals from south-central Pyrenees (Tremp Formation, Spain) and their bearing on late Paleocene marine-continental correlations
Ten mammalian taxa have been recovered from four localities in the upper part of the Tremp Formation (south-central Pyrenees). Its stratigraphic position allows the localities to be correlated with
Re-interpretation of the genus Parabunodon (Ypresian, Turkey): implications for the evolution and distribution of pleuraspidotheriid mammals
The reassessment of dental features of this genus as well as of its phylogenetic relationships led us to reconsider the taxonomic assignment of this still enigmatic form, and cladistic analysis supports the relationships of Parabunodon with other pleuraspidotheriids.
New data on the Oxyaenidae from the Early Eocene of Europe; biostratigraphic, paleobiogeographic and paleoecologic implications.
The locality of Le Quesnoy (France; MP7) has yielded a diversified mammal fauna including especially large mammals. Oxyaenidae are well documented with two species identified: Oxyaena woutersi and
Mammals from the Paleocene—Eocene transition in Belgium (Tienen Formation, MP7): Palaeobiogeographical and biostratigraphical implications
Mammal faunas from five outcrop sections in the Tienen Formation (Dormaal, Orp-le-Grand, Hoegaarden, Erqueiinnes, and Levai), representing the Paleocene-Eocene transition in Belgium, have been
