Abstract The carbon isotope composition of tooth enamel from all five mosasaur taxa known to date from the type Maastrichtian (southeast Netherlands, northeast Belgium) has been analysed. Differences in enamel δ 13 C values between taxa suggest resource partitioning. Body size and δ 13 C value correlate surprisingly well, with larger taxa having δ 13 C values more depleted in the heavier 13 C isotope.
