Sea surface temperature contributes to marine crocodylomorph evolution [PDF]

open access: yes, 2014
During the Mesozoic and Cenozoic, four distinct crocodylomorph lineages colonized the marine environment. They were conspicuously absent from high latitudes, which in the Mesozoic were occupied by warm-blooded ichthyosaurs and plesiosaurs.
