Deltadromeus was a contemporary of two other, much larger carnivores, Carcharodontosaurus and Spinosaurus. While the three very likely competed for meat, their different morphologies might have relegated them to different ecological niches: The nimble Deltadromeus might have served as the mid-Cretaceous equivalent of a cheetah, running down small to medium-sized prey. The bulkier, Carcharodontosaurus, meanwhile, may have been like a lion, bringing down larger prey alone or in packs, while the huge, fish-eating Spinosaurus would have been like a prehistoric grizzly bear, with a diet biased towards fish yet large enough to bring down large game or at least steal it from smaller predators.
