For humans or other large animals, this might involve analyzing the forces exerted by muscles, tendons and gravity on an individual’s skeletal (or other supporting) structures.

theropod A usually meat-eating dinosaur that belonged to a group whose members are typically bipedal (walk on two legs). They range from small and delicately built to very large.The mandibles help keep the food in place while also ripping off pieces of it, so it fits better in the mouth. Sound quality: No animal in distress sounds “pretty,” but an experienced ear can tell what sounds real.

Tyrannosaurus rex A top-predator dinosaur that roamed Earth during the late Cretaceous period. Adults could be 12 meters (40 feet) long. Furthermore, the Feral Predator got his mandible pulled off by Naru who then stabbed him in the shoulder with it. Lauder, George V.; Liem, Karel F. (November 1981). "Prey capture by Luciocephalus pulcher: implications for models of jaw protrusion in teleost fishes". Environmental Biology of Fishes. 6 (3–4): 257–268. doi: 10.1007/bf00005755. ISSN 0378-1909. S2CID 24315046. Similarly, A. fragilis had its strongest bite with a gape angle of 32.5 degrees. But the new analysis find this dino could open its mouth a whopping 92 degrees. That’s more than a right angle! predator (adjective: predatory) A creature that preys on other animals for most or all of its food.However, the Predators in the movies are often with open mouths, owing to the difficulty of making the closed-mouth effect. Yautja mandibles (also known as tusks) are one of the most recognizable features of the Predators from the movies and an important part of the Yautja anatomy. Freeze factor: In colder regions, having a call freeze up is a real concern, and more than one call has been slung into the brush because it froze at an inopportune moment.
