Elbow Joint Geometry in Bears (Ursidae, Carnivora): a Tool to Infer Paleobiology and Functional Adaptations of Quaternary Fossils

Bears are currently represented by eight species among Carnivora. Being all particularly large and generally plantigrade limits to certain extent their functional morphology so that inferences about their past diversification are difficult to achieve. We analyzed variation in bears’ elbow joint size and shape to reconstruct paleobiology of Quaternary fossil species. By using 2D geometric morphometrics, we were able to discriminate with high degree of accuracy species, locomotor and habitat…

Functional morphology and paleoecology of Pilosa (Xenarthra, Mammalia) based on a two‐dimensional geometric Morphometrics study of the Humerus
The relationship between humerus shape and the modes of exploring substrate among extinct and extant Pilosa (especially anteaters and ground sloths) were investigated here and suggest that plesiomorphic taxa such as Nothrotheriidae, most Megalonychidae and basal Megatheriidae tend to have more slender humeru, associated to generalist habitus, and while Mylodontidae developed specialized digging habitus.
Postcranial elements of small mammals as indicators of locomotion and habitat
It is demonstrated that the morphology of long bone joint anatomy (specifically articular surfaces) may be useful for determining the locomotor mode of Mesozoic mammals, at least for the therian mammals.
Functional traits of the world’s late Quaternary large-bodied avian and mammalian herbivores
HerbiTraits provides a tool for the analysis of herbivore functional diversity both past and present and its effects on Earth’s ecosystems, and includes key traits that influence how herbivores interact with ecosystems, namely body mass, diet, fermentation type, habitat use, and limb morphology.


Feeding habits of extant and fossil canids as determined by their skull geometry
Both skull size and shape are excellent predictors of feeding habits in Canini and provide information about fossil taxonomic affinities, and discriminant function analysis successfully classify extant Canini in dietary groups with 89% of accuracy.
Ecomorphological correlates of craniodental variation in bears and paleobiological implications for extinct taxa: an approach based on geometric morphometrics
Results reveal a set of shared craniodental traits among the herbivorous bears, including short and vaulted skulls with well-developed zygomatic arches, lateralized orbits and small canines, concave jaws with a highly positioned condyle, large moment arms for the temporalis and masseter muscles, and long cheek teeth.
Ecomorphology of Radii in Canidae: Application to Fragmentary Fossils from Plio-Pleistocene Hominin Assemblages
This study uses morphometry of the radius in extant carnivorans of the dog family (Canidae) to predict adaptation to prey size and introduces a new method for quantifying canid habitat adaptations based on the geographic distributions of the extant species sampled.
Feeding Habits of Plio-Pleistocene Large Carnivores as Revealed by the Mandibular Geometry
A complete geometric morphometric survey of mandible of large (>7 kg) Carnivora is presented in order to make paleoecological predictions for selected Plio-Pleistocene taxa.
Locomotor adaptations in Plio-Pleistocene large carnivores from the Italian Peninsula: Palaeoecological implications
Mammalian carnivores are rarely considered for environmental reconstructions because they are extremely adaptable and their geographic range is usually large. However, the functional morphology of
Cats in the forest: predicting habitat adaptations from humerus morphometry in extant and fossil Felidae (Carnivora)
Abstract Mammalian carnivores are rarely incorporated in paleoenvironmental reconstructions, largely because of their rarity within the fossil record. However, multivariate statistical modeling can
Functional morphology of the cave bear (Ursus spelaeus) mandible: a 3D geometric morphometric analysis
The mandibular morphology of cave bears was analysed using 3D geometric morphometrics and compared to that of extant Ursidae, implying the development of morphological adaptations for eating foliage.
Ecomorphological indicators of feeding behaviour in the bears (Carnivora: Ursidae)
Comparison of patterns of morphological variation and patterns of phylogenetic relationships among species revealed surprisingly strong congruence between morphology and phylogenetics.
Functional morphology of the cave bear (Ursus spelaeus) cranium: a three-dimensional geometric morphometric analysis
The cranial morphology of U. spelaeus was analysed using 3D geometric morphometrics and compared to that of extant Ursidae, and results suggest that the diet of the fossil bear Ursus spelaeus likely consisted mostly of foliage.
Postcranial morphology and the locomotor habits of living and extinct carnivorans
The authors' ANOVA results reveal consistent differences in postcranial skeletal morphology among locomotor groups, with cursorial and arboreal species more accurately classified than terrestrial, scansorial, or semiaquatic species.
