The observed variation in AILD among cave bears from different localities was best explained by their size, which in turn is correlated to the altitude of cave entrance. American badger T. Here, we aim to study several aspects of the bone histology of cave bears: 1 we describe the general histology of the femora of cave Sex dating Ursus compared to extant relatives, 2 we aim to reconstruct growth of cave bears by using average inter-LAG distance AILD as a proxy and compare it to extant relatives, 3 we present a hypothesis on some life history variables for cave bears based on the investigated growth, and 4 we examine the intraspecific variation in growth in Sex dating Ursus context of the altitude of the excavation site in order to elucidate if the investigated growth is different in the smaller cave bear populations from high altitudes.
