The Evolution of Mosasaurid Foraging Behavior Through the Lens of Stable Carbon Isotopes
A large data set of new and previously published measurements of δ13C values derived from tooth enamel (n = 223, of which 93 are new) are compiled to explore patterns of foraging area preferences of Late Cretaceous mosasaurid squamates over evolutionary time scales (~93–66 Ma). Our results indicate that small-bodied halisaurines are restricted to a relatively nearshore range, overlapping the lower
