摘要：

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