The solution was elegant. The digestive system could be lengthened and bipedal balance improved at the same time, for more intestinal tubing located to the rear of the hip joint clearly helped to balance the weight of the body before it. Although the beaked dinosaur classes are totally extinct nowadays, a quite vivid picture of their intestinal arrangements can be obtained from a chicken, turkey, or any modern bird. In birds, the gastrointestinal tract passes right under the hips all the way to the end of the pubis below the base of the tail. And birds obtain the same advantages for balance and strength as did the dinosaurs. (dinosaur manufacturers)Birds—like early beaked dinosaurs—are bipeds when they walk, and their intestinal arrangement allows them easy balance on their hindlegs. In the air, all the force of the wingbeat passes through the upper shoulder joint, and the design of the intestines lets birds have very short, very strongly braced torsos to anchor the stresses and strains of flying.
Some beaked dinosaurs had every possible plant-digesting device—the parrot dinosaurs, for example, had
(1) strong, deep beaks
(2) closely packed teeth
(3) large jaw muscles
(4) a fore-stomach gastric mill with stomach stones,
(5) a long intestine.
These parrot dinosaurs were the ultimate in dietary adaptation. (lifelike dinosaur for sale)They were, however, exceptions to the rule. Most advanced beaked dinosaurs heavily developed one type of digestive device or another, not all at once.
