What was Xiphactinus's ecological status among predatory Osteichthyes in its environment?

Answer

It represented the pinnacle of predatory Osteichthyes

Xiphactinus occupied the apex slot in its ecosystem, placing it firmly at the top of the local food pyramid. Specifically within the context of bony fish (Osteichthyes) in its Late Cretaceous marine setting, the creature represented the pinnacle of predatory success. Its dominance was secured by its consistent ability to out-compete other large predators by securing sizable, high-calorie prey items available in its warm, shallow sea habitat.
