Evidence for an African-Iberian mammal dispersal during the pre-evaporitic Messinian
The accurate timing of biogeographic dispersal can be determined by examining the age of fossiliferous strata on either side of a physical barrier. Here we show that African mammals migrated to…
Kretzoiarctos gen. nov., the Oldest Member of the Giant Panda Clade
A new ailuropodine genus is described, Kretzoiarctos gen. nov., based on remains from two Middle Miocene Spanish localities, which can be considered the oldest recorded member of the giant panda lineage, which has significant implications for understanding the origins of this clade from a paleobiogeographic viewpoint.
First Early Pliocene micromammal faunas from Venta del Moro (Cabriel Basin, Spain): new data on the Messinian dispersal of Debruijnimys
Based on the study of the micromammal assemblages from the localities of La Bullana 2B and La Bullana 3 (Valencia, E Spain) we propose an Early Pliocene age (MN14) for both sites. The presence of a…

A new elasmobranch assemblage is described from the rich fossil site of Montañita-Olón (Dos Bocas Formation, Santa Elena, Ecuador), where other vertebrates have already been described: for example, sea turtles and cetaceans.

ABSTRACT We describe cranial, mandibular, and dental remains of five individuals of the giant mustelid Eomellivora piveteaui Ozansoy, 1965, from the late Miocene (MN10) site of Cerro de los…
Anatomy of the “false thumb” of Tremarctos ornatus (Carnivora, Ursidae, Tremarctinae) : phylogenetic and functional implications
The radial sesamoid or “false thumb” of the spectacled bear (Tremarctos ornatus) is described, showing its great morphological similarities with that of the giant panda (Ailuropoda melanoleuca) and the differences with the rest of the Ursidae.
Una nueva especie de Agriarctos (Ailuropodinae, Ursidae, Carnivora) en la localidad de Nombrevilla 2 (Zaragoza, España)-A New species of Agriarctos (Ailuropodinae, Ursidae, Carnivora) in the…
The present study documents a new primitive ursid species, Agriarctos beatrix from the Spanish locality of Nombrevilla 2 (Calatayud-Daroca basin, province of Zaragoza). The new fossils of Nombrevilla…
Tracing the origin of the panda’s thumb
In the two extant pandas, the false thumb should not be interpreted as an anatomical convergence, but as an exaptive convergence regarding its use during the bamboo feeding, which changes the evolutionary view of this singular structure.
