1 . In each set, incisors (I) are indicated first, canines (C) second, premolars (P) third, and finally molars (M), giving I:C:P:M. So for example, the formula 2.1.2.3 for upper teeth indicates 2 incisors, 1 canine, 2 premolars, and 3 molars on one side of the upper mouth. (2014):[35], The second alternative phylogenetic hypothesis was implemented by McKenna et al. Based on genetic and morphological data, the Ailuropodinae (pandas) were the first to diverge from other living bears about 19 Mya, although no fossils of this group have been found before about 5 Mya. [12] Modern bears comprise eight species in three subfamilies: Ailuropodinae (monotypic with the giant panda), Tremarctinae (monotypic with the spectacled bear), and Ursinae (containing six species divided into one to three genera, depending on the authority). [105] Bears normally do not wake during their hibernation, and can go the entire period without eating, drinking, urinating, or defecating. [26] They invaded South America (≈2.5 or 1.2 Ma) following formation of the Isthmus of Panama. Agriotheriinae [42][43] Body weight varies throughout the year in bears of temperate and arctic climates, as they build up fat reserves in the summer and autumn and lose weight during the winter. The limbs are much straighter than those of the big cats as there is no need for them to flex in the same way due to the differences in their gait. [93], Gestation typically lasts 6–9 months, including delayed implantation, and litter size numbers up to four cubs. The teeth start the breakdown process of the food the bear eats. [36] Amphicynodontinae under this classification were classified as stem-pinnipeds in the superfamily Phocoidea. More. [55] The sun bear's range extends below the equator in Southeast Asia. The dental formula can be determined by dividing the skull in the middle, then starting at the symmetrical midpoint and counting the teeth moving backwards along the jaw.
