mouth of a dinosaur?

Question

i would like to know about the mouth of a dinosaur

Answer 1

Dinosaur mouths, like the mouths of any other critters, are adapted to the type of diet. Herbivores will have grinding teeth to crush vegetation. Carnivores will have sharp teeth for tearing flesh.

Answer 2

Like the poster above said, dinosaurs have different mouths depending on their diet. However in general, all dinosaurs have akinetic skulls, which means that their jaws can bite in several different flexible ways, as opposed to just one way (up and down). An akinetic skull means there are muscles and bones which allow the biting animal to change the shape of its bite to better grip prey items, mostly so that they don't slip out. Herbivores have an akinetic skull so they can accomplish grinding motion with their jaws. (Kinetic skulls, which we see in mammals and the like, only bite straight down. This isn't the best design for gripping prey items, but as you see in carnivores, all they need is very strong killing bite, which is what a kinetic skull accomplishes.)

The inside of the mouth also depends on the type of dinosaur. Herbivores mainly have grinding teeth, hard, flat shapes for mashing tough plant material. Some herbivores, however, like the diplodocids, have small teeth in the front for biting off pieces of vegetation, which they may swallow whole.

Carnivores have teeth depending on whether or not they were scavengers or predators. Predators have sharp teeth, usually with serrated edges (like steak knives, the little ridges help grip prey and possibly trap bacteria that infect their victims and make them die faster). Scavengers also have pointed teeth, but probably to a lesser degree.

Hope that helped!
