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 δ13C values between taxa suggest resource partitioning. Body size and δ13C value correlate surprisingly well, with larger taxa having δ13C values more depleted in the heavier 13C isotope.
