Duckbills possessed cranial Cuisinarts par excellence


Duckbills possessed cranial Cuisinarts par excellence. They had developed the best teeth for shredding leaves and twigs into tiny bits. Large horned dinosaurs were the long-slicers, the best at cutting tough vegetables into digestible chunks. (china dinosaur factory)Yet neither duckbills nor horned dinosaurs have ever been found with gastroliths, even though dozens of good skeletons have been hewn out of the Late Cretaceous rocks. Probably these strong-jawed dinosaurs substituted the power of their teeth for stone power in the stomach. (animatronic dinosaur suit)And the size of their digestive system varied considerably in these species: wide-beaked duckbills had broad tail bones that supported enlarged colons and intestinal appendices; hollow-crested duckbills and horned dinosaurs were less enlarged in the rump.


The successful development of rearward fermenting vats pro-vides the solution to one of the biggest puzzles about plant-eating dinosaurs—the weak-gummed giants. Although brontosaurs, duckbills, and horned dinosaurs were all apparently well provided with grinders of one anatomical sort or another (teeth or gizzard stones or both), two groups of big plant-eating, beaked dinosaurs seem to have been totally unprepared for grinding plants: the armored ankylosaurs and the dome-headed dinosaurs. (real size dinosaur)Both groups seem to have followed the wrong evolutionary path—their teeth are smaller, weaker, and less tightly packed than in the ancestral early beaked dinosaurs.


Ankylosaur and domehead had tiny crowns on their teeth, and the teeth were loosely spaced in the huge bony jaws. (lifelike dinosaur)Traditional paleontologists looked at those mouths and con-cluded they couldn't have chewed anything tough with teeth like those. These dinosaurs must have had restricted diets of soft food and therefore low metabolic rates. As usual with such interpretations, they immediately arouse suspicion.


After all, ankylosaurs and domeheads were advanced dinosaurs bristling with specialized neck, skull, limbs, vertebrae, and armor. So the very logical question is: (life size dinosaur for sale)Were there any equally advanced gastrointestinal adaptations that might have compensated for this chewing apparatus? There was indeed: giant afterburners.
