Habitat preferences of European Middle Miocene omnivorous ursids
نویسنده
چکیده
Indarctos spp. were the first large−bodied bears with omniv− orous tendencies. Two Indarctos fossils assigned to I. arcto− ides ssp. by Bernor, Feibel, et al. (2003) and Viranta and Werdelin (2003) show that the genus had a wide geographic range in Europe in theMiddleMiocene andwas represented by at least two contemporaneous species. Present work shows that the two species of Indarctos lived in a mixture of environments, and were not clearly separated into distinct habitats. Indarctos seems to have evolved during an interval of faunal turnover in Europe. The appearance of Indarctos coincided with an extinction of small omnivorous mammals and was accompanied by the appearance of other large omnivores.

Was the Giant Short-Faced Bear a Hyper-Scavenger? A New Approach to the Dietary Study of Ursids Using Dental Microwear Textures
Dramatic environmental changes associated with global cooling since the late Miocene, and the onset of glacial-interglacial cycles in the Pleistocene served as a backdrop to the evolutionary radiation of modern bears (family Ursidae). These environmental changes likely prompted changes in food availability, and triggered dietary adaptations that served as motive forces in ursid evolution. Here,...

The earliest record of plant visiting in bats dates to the Middle Miocene of La Venta, the world's most diverse tropical palaeocommunity. Palynephyllum antimaster is known from molars that indicate nectarivory. Skull length, an important indicator of key traits such as body size, bite force and trophic specialization, remains unknown. We developed Bayesian models to infer skull length based on ...
متن کاملUsing ecological niche modeling for quantitative biogeographic analysis: a case study of Miocene and Pliocene Equinae in the Great Plains
—The subfamily Equinae in the Great Plains region of North America underwent a dramatic radiation and subsequent decline as climate changed from warm and humid in the middle Miocene to cooler and more arid conditions during the late Miocene. Here we use ecological niche modeling (ENM), specifically the GARP (Genetic Algorithm using Rule-set Prediction) modeling system, to reconstruct the geogra...

The New Zealand endemic bat family Mystacinidae comprises just two Recent species referred to a single genus, Mystacina. The family was once more diverse and widespread, with an additional six extinct taxa recorded from Australia and New Zealand. Here, a new mystacinid is described from the early Miocene (19-16 Ma) St Bathans Fauna of Central Otago, South Island, New Zealand. It is the first pr...
