Abstract Three major carnivoran dispersal waves of filter-bridge type between Eurasia and North America are recognized in the late Neogene. The first is around 20 Ma, probably from 21 Ma to 19–18 Ma, during which intermittent dispersals might have occurred. The carnivorans migrating from Eurasia to North America included Cynelos, Ysengrinia, Amphicyon, Cephalogale, Phoberocyon, Ursavus, some small-sized mustelids, Potamotherium, an ancestral form of Edaphocyon, and Proailurus. The second wave… 

A Skull of the Immigrant Eurasian Beardog Cynelos (Carnivora, Amphicyonidae) from the Early Miocene of Southern California

ABSTRACT At ∼23 Ma, large amphicyonid carnivorans participated in the initial Neogene mammal migration passing though the Bering filter en route to North America. Among the migrants were the

Neogene tectonics and climate forcing of carnivora dispersals between Asia and North America

Abstract. Exchange records of terrestrial mammals can be combined with available tectonic and climatic documents to evaluate major biological and environmental events. Previous studies identified

Ursidae (Mammalia, Carnivora) from the Late Oligocene of the “Phosphorites du Quercy” (France) and a reappraisal of the genus Cephalogale Geoffroy, 1862

This work reports on karstic fissure fillings from the Quercy (France) which give an exceptional open laboratory for the study of evolution of vertebrates and especially mammals from the Eocene to the Early Miocene, and yields the best sample ever found of a hemicyonine ursid.

A new species of Gulo from the Early Pliocene Gray Fossil Site (Eastern United States); rethinking the evolution of wolverines

Detailed comparison indicates Plesiogulo, which has often been suggested to be ancestral to Gulo, is not likely closely related to gulonines, and instead may represent convergence on a similar niche, which suggests wolverines may have become ‘cold-adapted’ relatively recently.

Amphicyon zhanxiangi, sp. nov., a new amphicyonid (Mammalia, Carnivora) from northern China

A maxillary fragment with P4–M2 and the M3 alveolus from the early middle Miocene Dingjia’ergou fauna, Tongxin, northern China is reported, showing the enlarged and anteroposteriorly elongated M2 with Amphicyon zhanxiangi and could be a descendant of the latter species.

ABSTRACT The occurrence of the Tribe Canini (subfamily Caninae) in the Hemphillian (Mio-Pliocene) of North America has been long known without finding contemporary relatives in the Old World.

The first Old World occurrence of the North American mustelid Sthenictis (Mammalia, Carnivora)

A new immigrant mustelid from the Tunggur Formation in Inner Mongolia is described, composed of two partial dentaries which represent the first occurrence of this genus outside North America and seems to represent that of a basal lineage with intermediate morphology.

A New Cursorial Hyena from Tibet, and Analysis of Biostratigraphy, Paleozoogeography, and Dental Morphology of Chasmaporthetes (Mammalia, Carnivora)

ABSTRACT Recent field work in the late Cenozoic Zanda Basin in southwestern Tibetan Plateau has provided new fossil evidence of vertebrate faunas spanning the late Miocene to Pleistocene, which

Middle Miocene carnivorans from the Monarch Mill Formation, Nevada

The lowest part of the Monarch Mill Formation in the Middlegate basin, west-central Nevada, has yielded a middle Miocene (Barstovian Land Mammal Age) vertebrate assemblage, the Eastgate local fauna.

Tertiary Procyoninae (Mammalia: Carnivora) of North America

Cladistic analysis demonstrates that Paranasua is the primitive sister taxon of Procyon and Nasua; that Arctonasua is probably most closely related to the late Tertiary Cyon asua group of South American procyonines; and that the primitive Sister group of the Procy oninae discussed in this paper includes Bassariscus and the European Agenian and Orleanian genus Broiliana.

Relationship of Pinnipeds to Other Carnivores (Mammalia)

The osteological evidence supports a specific sister-group relationship of the otariids with the ursids and of the phocids (including Potamotherium and its close relative Semantor) with the mustelids within the Arctoidea.
