Inspired by divingwolf's recent posts, I wanted to create a Cave bear index thread where I could post data to compliment relating threads whereby other members can use draw/use from the cited professional literature as they see fit.
BARYSHNIKOV , G., GERMONPRÉ, M. & SABLIN, M., 2003. Sexual dimorphism and morphometric variability of check teeth of the cave bear (Ursus spelaeus)- Belg. J. Zool., 133 (2): 111-119, Brussels.
The sexual dimorphism and the morphometric variability of the cheek teeth in Ursus spelaeus from six geographically well-separated localities dating from the Middle Weichselian were studied. The sexual dimorphism of the canines and of the lower carnassials (m1) of the cave bear are as much or more expressed than the dimorphism of these teeth in the Recent brown bear. The examined cave bear assemblages are rather similar in tooth size and proportions. The differences between the assemblages were presumably influenced by the ratio of male to female bears. The posterior cheek teeth M2 and m3 allowed us to divide more northern (Goyet in Belgium, Niedzwiedzia in Poland, and Medvezhiya Cave in European Russia) from more southern (Eirós in Spain, Arcy-sur-Cure in France, and Odessa in Ukraine) sites. These grouping suggest a difference in the diet of the cave bears in the northern and southern parts of the species distribution range, at least during the time segments studied.

As a result of the morphometric study, tooth samples examined in 17 sites of Western and Eastern Europe and the Caucasus were distributed into two groups. The first group is formed by teeth from localities of the Middle Pleistocene and from the Late Pleistocene layers 3-4 of Kudaro 3 Cave, which were identified as Ursus deningeri. The second group united specimens from the Late Pleistocene localities attributed to U. spelaeus. The sample from Furtins Cave in France was shown to occupy a transitional position. The teeth from Bacton Forest Bed in England and from Kizel Cave in the Ural Mountains resemble those in the first group, revealing, nevertheless, some difference; despite the produced analysis allows no confidence in the establishment of their species attribution, these may be tentatively referred to U. savini.

In this paper the influence of sex dimorphism in the population of cave bears from Cova Eirós (Triacastela, Galicia, Spain) is reviewed. The study will be centred in the skull, jaw and teeth, and principally in those parts that are commonly considered as not markedly dimorphic.
