a new hypercarnivorous Mustelid mammalia carnivora Mustelidae from batallones late miocene mn10 torrejon de velasco madrid spain
Geodiversitas, 2020Co-Authors: Alberto Valenciano, Juan Abella, Alejandro Perezramos, Jorge MoralesAbstract:We describe dentognathic remains of four individuals of the poorly known Mustelid CircamustelaPetter, 1967 from the late Miocene sites of Batallones-3 and 5 (MN10, Torrejon de Velasco, Madrid, Spain). These new fossils allow us to describe Circamustela peignei n. sp., a more primitive species than Circamustela dechaseauxiPetter, 1967 from Can Llobateres (MN9, Valles Penedes Basin, Spain). Circamustela peignei n. sp. shows, among other features, an M1 with a more developed metacone, a smaller metastylar area, a mesially located protocone, and a more developed m1 metaconid compared to that of C. dechaseauxi. The new taxon differs from most Euroasian Miocene marten-like Mustelids, such as the middle Miocene martens “Martes” sansaniensis (Lartet, 1851), and “Martes” filholiDeperet, 1887, the vallesian Martes melibullaPetter, 1963 and the Turolian/Ventian Martes woodwardiPilgrim, 1931, Martes ginsburgi Montoya, Morales & Abella, 2011, Pekania palaeosinensis (Zdansky, 1924), and Paramartes pocockiKretzoi, 1952, in smaller size, a reduced lingual platform of the M1 and a more reduced m1 talonid and m2. However, C. peignei n. sp. is closer to the Chinese and Greek hypercarnivorous Sinictis dolichognathusZdansky, 1924. Circamustela spp., and SinictisZdansky, 1924 can be interpreted as adapted to a more carnivorous diet than those of the more generalist martens, such as Martes spp., ParamartesKretzoi, 1952 and Pekania spp.

new early miocene material of iberictis the oldest member of the wolverine lineage carnivora Mustelidae guloninae
Journal of Mammalian Evolution, 2020Co-Authors: Alberto Valenciano, Juan Abella, Maria Angeles Alvarezsierra, David M Alba, Josep M Robles, Jorge MoralesAbstract:We describe new dental remains of the genus Iberictis (Carnivora: Mustelidae) from the late early Miocene of the Iberian Peninsula. The new fossils of Iberictis azanzae from Artesilla (16.5–16.3 Ma, MN4; Calatayud-Teruel Basin, Zaragoza, Spain) add important morphological information about this species. Material from another species, Iberictis buloti, is described from els Casots (16.5–16.3 Ma, MN4; Valles-Penedes Basin, Barcelona, Spain). This material constitutes the most complete sample of Iberictis and the first record of I. buloti in the Iberian Peninsula. Our analyses confirm the taxonomic validity of both species, and confirm the more plesiomorphic status of I. buloti compared to I. azanzae. Re-examination of large Mustelid Miocene genera (Dehmictis, Ekorus, Eomellivora, Hoplictis, Iberictis, Ischyrictis, and Plesiogulo) and their inclusion for the first time in a cladistic analysis indicate that Iberictis is the sister taxon of Plesiogulo, and that these genera constitute the sister group of the extant wolverine (Gulo gulo). Our analysis thus confirms a close relationship between the early Miocene Iberictis, the late Miocene Plesiogulo, and the Plio-Pleistocene Gulo. Iberictis is the oldest member of Gulonini, the total clade of wolverines, thereby tracking the fossil record of this clade back to the early Miocene. We further propose a new systematic arrangement for the aforementioned large Miocene Mustelids into the subfamilies Guloninae, Mellivorinae, and Mustelinae.

megalictis the bone crushing giant Mustelid carnivora Mustelidae oligobuninae from the early miocene of north america
PLOS ONE, 2016Co-Authors: Alberto Valenciano, Jon A Baskin, Juan Abella, Alejandro Perezramos, Angeles Angeles Alvarezsierra, Jorge Morales, Adam HartstoneroseAbstract:We describe cranial and mandibular remains of three undescribed individuals of the giant Mustelid Megalictis ferox Matthew, 1907 from the latest Arikareean (Ar4), Early Miocene mammal fauna of Nebraska, and Wyoming (USA) housed at the American Museum of Natural History (New York, USA). Our phylogenetic hypothesis indicates that Ar4 specimens assigned to M. ferox constitute a monophyletic group. We assign three additional species previously referred to Paroligobunis to Megalictis: M. simplicidens, M. frazieri, and “M.” petersoni. The node containing these four species of Megalictis and Oligobunis forms the Oligobuninae. We test the hypothesis that Oligobuninae (Megalictis and Oligobunis) is a stem Mustelid taxon. Our results indicate that the Oligobuninae form the sister clade to the crown extant Mustelids. Based on the cranium, M. ferox is a jaguar-size Mustelid and the largest terrestrial Mustelid known to have existed. This new material also sheds light on a new ecomorphological interpretation of M. ferox as a bone-crushing durophage (similar to hyenas), rather than a cat-like hypercarnivore, as had been previously described. The relative large size of M. ferox, together with a stout rostrum and mandible made it one of the more powerful predators of the Early Miocene of the Great Plains of North America.

complete description of the skull and mandible of the giant Mustelid eomellivora piveteaui ozansoy 1965 mammalia carnivora Mustelidae from batallones mn10 late miocene madrid spain
Journal of Vertebrate Paleontology, 2015Co-Authors: Alberto Valenciano, Juan Abella, Adam Hartstonerose, Oscar Sanisidro, Maria Angeles Alvarezsierra, Jorge MoralesAbstract:ABSTRACTWe 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 Batallones (Madrid, Spain)—the first complete cranial remains recorded for this species and the most complete remains of the genus. This new sample enables a review of the systematic status of Eomellivora, leading us to accept as valid the species E. piveteaui Ozansoy, 1965, E. wimani Zdansky, 1924, E. ursogulo (Orlov, 1948), and E. hungarica Kretzoi, 1942. Our phylogenetic hypothesis indicates that Eomellivora is the sister taxon of the extant Mellivora capensis and E. piveteaui had a common ancestor within the crown group E. wimani–E. ursogulo. Eomellivora piveteaui was specialized for a more hypercarnivorous diet than the largest extant terrestrial Mustelids, although it also had some derived bone-crushing adaptations. Eomellivora piveteaui had an active predatory role in the late Miocene carnivore faunas, exploiting...

new remains of a primitive badger from cueva de los toriles carrizosa castilla la mancha iberian peninsula suggest a new quaternary locality in the southern iberian plateau
Journal of Iberian Geology, 2020Co-Authors: Daniel Garciamartinez, Alberto Valenciano, Aitziber Suarezbilbao, Carlos A Palancar, Irene Megia Garcia, Davinia Moreno, Isidoro Campana, Pedro R MoyamalenoAbstract:The Cueva de Los Toriles belongs to a karstic system found in the southern Iberian plateau. Construction works in the cave (not related to paleontological activities) have allowed for the recovery of fossil remains of macromammals, including two lower molars of a Mustelid that are presented in this work. They can be attributed to the species Meles cf. thorali based on morphological and morphometric comparisons. This extinct Mustelid is known mostly from Villafranchian deposits of France, Spain, and Greece spanning from the late Pliocene potentially, even reaching with some doubts the Early-Middle Pleistocene of France. Therefore, according to the presence of this badger in the cave, we could tentatively assume a chronological age ranging from the Late Pliocene to the Middle Pleistocene, chronologies that would be consistent with some lithic tools found in the cave. We highlight the importance of Cueva de Los Toriles for the Quaternary Paleontology of the southern Iberian plateau, one of the places from the Iberian Peninsula with a more limited fossil record from these chronologies.
