Plain Language Explanation: Predatory dinosaurs such as Allosaurus carried clear anatomical tools for attacking and processing prey: serrated teeth, powerful jaws, muscular hind limbs and clawed forelimbs. Fossil injuries, tooth marks and feeding traces can sometimes move the interpretation from 'this animal could attack' to direct evidence that an attack or feeding event actually occurred.

Evidence: Allosaurus possessed serrated teeth adapted to cutting flesh.; Its forelimbs carried large curved claws.; Bite marks and paleopathological injuries can document actual predator-prey interactions in exceptional cases.

Examples From Collection: Allosaurus fragilis; Camptosaurus dispar; Stegosaurus stenops

Interaction Guard: The co-display of Allosaurus and herbivorous dinosaurs does not prove that the specific displayed individuals interacted.

Common Misconception: Predatory anatomy does not tell us every detail of hunting behavior. Claims about pack hunting, ambush tactics or preferred prey require separate evidence.

What Scientists Still Debate: How Allosaurus selected prey, whether individuals sometimes cooperated, and the exact mechanics of attack remain active areas of research.

Enrichment Method: SAGE original interpretive concept; direct anatomy separated from behavior and reconstruction; reproductive, growth and gigantism claims tied to specific fossil or comparative evidence
