Abstract Mammals exhibit ecology‐related diversity in long bone morphology, revealing an ample spectrum of adaptations both within and between clades. Their occupation unique ecological niches postcranial morphology is thought to have occurred at different chronological phases relation abiotic factors such as climate biotic interactions amongst major Mammalian morphologies rapidly evolved throughout the Cenozoic, with several orders following paths locomotory adaptations. We assessed morphological variation limb proportions for a rich sample extant fossil large mammalian clades (mainly carnivores ungulates) test associations identify temporal patterns diversification. Phylogenetic relationships among species were incorporated into analysis proportions, showing significant changes substrate preference. Major climatic events appeared no impact on diversification, expressed disparity, either or groups. Linear stochastic differential equations supported double‐wedge diversification model carnivorous (‘Creodonta’ Carnivora). The concomitant increase disparity Cenozoic Carnivora Artiodactyla had significative Perissodactyla supporting interaction primary driver Our findings challenge classic idea driving forces evolution terrestrial mammals, propose clade competition key factor
