What size were Arctodus simus and Ursus spelaeus (Carnivora: Ursidae)?
Body masses of the giant short-faced bear (Arctodus simus Cope) and the cave bear (Ursus spelaeus Rosenmüller & Heinroth) were calculated with equations based on a long-bone dimensions:body mass proportion ratio in extant carnivores. Despite its more long-limbed, gracile and felid-like anatomy as compared with large extant ursids, large Arctodus specimens considerably exceeded even the largest ...
متن کاملTaxonomic review of fossil Proboscidea (Mammalia) from Langebaanweg, South Africa
Comparative morphological and metric study of proboscidean dental fossils from the Quartzose (QSM) and Pelletal Phosphate (PPM) Members of the Varswater Formation at Langebaanweg, South Africa, identifies the presence in the fauna of an anancine gomphothere and two species of elephant. The gomphothere, from the QSM and PPM, displays a unique combination of primitive and derived molar features, ...
متن کاملAn exceptional fossil skull from South America and the origins of the archosauriform radiation
Birds, dinosaurs, crocodilians, pterosaurs and their close relatives form the highly diverse clade Archosauriformes. Archosauriforms have a deep evolutionary history, originating in the late Permian, prior to the end-Permian mass extinction, and radiating in the Triassic to dominate Mesozoic ecosystems. However, the origins of this clade and its extraordinarily successful body plan remain obscu...
متن کاملNo need to replace an “anomalous” primate (Primates) with an “anomalous” bear (Carnivora, Ursidae)
By means of mitochondrial 12S rRNA sequencing of putative "yeti", "bigfoot", and other "anomalous primate" hair samples, a recent study concluded that two samples, presented as from the Himalayas, do not belong to an "anomalous primate", but to an unknown, anomalous type of ursid. That is, that they match 12S rRNA sequences of a fossil Polar Bear (Ursusmaritimus), but neither of modern Polar Be...
متن کاملLate Pleistocene carnivores (Carnivora: Mammalia) from a cave sedimentary deposit in northern Brazil.
The Brazilian Quaternary terrestrial Carnivora are represented by the following families: Canidae, Felidae, Ursidae, Procyonidae Mephitidae and Mustelidae. Their recent evolutionary history in South America is associated with the uplift of the Panamanian Isthmus, and which enabled the Great American Biotic Interchange (GABI). Here we present new fossil records of Carnivora found in a cave in Au...
