ABSTRACT A new Pliocene river otter is described from the Hagerman Fossil Beds (Hagerman Fossil Beds National Monument), Idaho. Lontra weiri, sp. nov., exhibits notable lutrine traits that closely align it to Old World Lutra and New World Lontra, which are morphologically similar but diphyletic. It is further assigned to Lontra based on known otter biogeography and molecular phylogenetic data. The Hagerman Fossil Beds are characterized by a Blancan North American Land Mammal Age fauna, and… 
Maybe So, Maybe Not: Canis lepophagus at Hagerman Fossil Beds National Monument, Idaho, USA
A canid dentary is described from the Pliocene Glenns Ferry Formation at Hagerman Fossil Beds National Monument, south-central Idaho, USA. The specimen possesses traits in alliance with and
Rediscovering Lutra lutra from Grotta Romanelli (southern Italy) in the framework of the puzzling evolutionary history of Eurasian otter
A river otter hemimandible has been rediscovered during the revision of the historical collections of G.A. Blanc from Grotta Romanelli, complementing the ongoing multidisciplinary research fieldwork
Ecology and biogeography of the Neotropical otter Lontra longicaudis: existing knowledge and open questions
Severe gaps in knowledge are found including aspects of life history, ground validation of new potential distribution areas and long-term population monitoring aiming at designing more efficient conservation measures and techniques and perspectives for future studies are presented.
Dispersal ability predicts evolutionary success among mammalian carnivores
A novel species-level phylogeny of all known extant and extinct species of the order Carnivora and related extinct groups is produced to show that there is instead a positive relationship between dispersal rate and diversification rate when all extinct species are included.
INTRODUCTION Since retiring to Florida I have had more free time to enjoy the wildlife around me. As I met people and we became acquainted they eventually discovered I was a zoologist. Many of these
Apport de la génétique pour l’étude de la dynamique des populations de Loutre d’Europe Lutra lutra (Linnaeus, 1758) en France
The simultaneous development of molecular methods allowed scientists to adopt non-invasive sampling techniques for the monitoring of the Eurasian otter and these methods rely on the collection of cues of the species presence and neither requires to capture nor to observe the species.


A Pleistocene Giant River Otter from Argentina: Remarks on the Fossil Record and Phylogenetic Analysis
This work describes and compares a very complete specimen of Pteronura found in Entre Ríos province using classical morphological descriptive and multivariate analyses, discusses the importance of this specimen for the fossil record of the taxon, and performs a preliminary phylogenetic analysis.
An Unexpected Early Record of Mictomys vetus (Arvicolinae, Rodentia) from the Blancan (Pliocene) Glenns Ferry Formation, Hagerman Fossil Beds National Monument, Idaho
The cooling during the Pliocene that preceded major continental glaciation in North America is recorded by thick fluvial and lacustrine sequences at Hagerman Fossil Beds National Monument (HAFO) in
Enhydriodon dikikae, sp. nov. (Carnivora: Mammalia), a Gigantic Otter from the Pliocene of Dikika, Lower Awash, Ethiopia
A new species of gigantic otter from the Pliocene of Dikika, in the lower Awash valley of Ethiopia, this species illustrates the culmination of general trends in this group, but the most remarkable part of its dentition is the broad incisor arch and powerful canine battery.
A new genus and species of sea otter, Enhydritherium terraenovae is described from Hemphillian deposits of the Withlacoochee 4A site and the Upper Bone Valley Formation, Florida and from the

First report of Lutra simplicidens (Carnivora, Mustelidae, Lutrinae) in the Early Pleistocene of the Upper Valdarno (Italy)and the origin of European otters
A right mandible of an otter from the Early Pleistocene of the Upper Valdarno Basin (Italy) kept in the collections of the Natural History Museum of London is reported, representing the oldest report of this species.
A revision of the Pliocene and Quaternary Lutrinae from Europe
In this paper, a revision of the Pliocene and Quaternary Lutrinae from Europe is presented. Such a revision, including fossil material, has not been published since the work of Pohle (1919). Three
The osteology and paleoecology of the giant otter Enhydritherium terraenovae
An incomplete skeleton of E. terraenovae recovered from the early Hemphillian Moss Acres Racetrack site in northern Florida includes a skull, mandible, part of the axial skeleton, and most of both the fore- and hindlimbs, adding greatly to knowledge of this animal.
The oldest Asian Sivaonyx (Lutrinae, Mustelidae): a contribution to the evolutionary history of bunodont otters
We describe here specimens of the otter Sivaonyx cf. gandakasensis from the late Middle Miocene hominoid-bearing basin of Chiang Muan, northern Thailand. Asian Sivaonyx species were previously
