Competition structured a Late Cretaceous megaherbivorous dinosaur assemblage

Abstract Modern megaherbivore community richness is limited by bottom-up controls, such as resource limitation and resultant dietary competition. However, the extent to which these same controls impacted the richness of fossil megaherbivore communities is poorly understood. The present study investi...
