Comment on “The influence of juvenile dinosaurs on community structure and diversity”

Schroeder et al. (Reports, 26 February 2021, p. 941) reported a size gap among predatory dinosaur species. We argue that the supporting dataset is skewed toward Late Cretaceous North America and that the gap was likely absent during other intervals in most geographic regions. We urge broader conside...

Summary:Schroeder et al. (Reports, 26 February 2021, p. 941) reported a size gap among predatory dinosaur species.

We urge broader consideration of this hypothesis, with quantitative evaluation of preservational and dataset biases.
