How big was allosaurus prey?

Allosaurus primarily preyed on large herbivorous dinosaurs, with targets often weighing between 1,000 to 2,000 pounds (450 to 900 kg). Its prey included dinosaurs like Stegosaurus and juvenile sauropods, which could be significantly larger than Allosaurus itself. The size of its prey varied, but Allosaurus was well-adapted to take down sizable animals through its powerful jaws and hunting strategies.
