The repeated returns of vertebrates to the marine ecosystems since Triassic serve as an evolutionary model understand macroevolutionary change. Here we investigate effects land-to-sea transition on disparity and constraint vertebral column in aquatic carnivorans (Carnivora; Pinnipedia) assess how their functional diversity innovations influenced major radiations crown pinnipeds. We use three-dimensional geometric morphometrics multivariate analysis for high-dimensional data under a phylogenetic framework quantify size shape living extinct Our demonstrates important shift evolution by 10-12 million years ago, from unconstrained constrained scenario, point time that coincides with radiation Moreover, also demonstrate axial skeleton phocids otariids followed different path morphological was probably driven specialized locomotor strategies. Despite this, found significant effect habitat preference (coastal versus pelagic) morphology taxa regardless family they belong. In summary, our provides insights into complex history pinniped morphology.
