Abstract in brief
The study compares the abundance of large carnivorous dinosaurs to large herbivorous dinosaurs from the Morrison Formation in the USA and the Dinosaur Park Formation in Canada, finding that large meat-eaters might have been more common than expected based on modern fossil ratios.
Models of dinosaur populations suggest that large theropods (carnivores) could have been more numerous than predicted by current mammal-based data, possibly due to differences in ecosystem productivity or diet.
The research indicates that the amount of plant-eating dinosaurs (herbivores) likely couldn't fully support the large number of carnivores unless the herbivores produced more biomass than expected or the carnivores ate a wider variety of prey, including other dinosaurs besides herbivores.]
Just back from fieldwork (stay tuned), during which time I co-published two new papers: one describing a juvie Gryposaurus skeleton and another modeling predator abundance in dinosaur ecosystems. Links below. #CMNPalaeo

According to this new study, megatheropods from the Morrison & Dinosaur Park Formations likely hunted small/medium-sized adult dinosaurs. The authors don't go into this, but this seems to imply competition between giant & smaller predators.
