If you like learning about dinosaurs, or if your child is a dinosaur fan, then you’ve come to the right place! Let’s take a peek inside the mouths of some of history’s most famous dinosaurs, including the Tyrannosaurus Rex, Velociraptor, Brachiosaurus, Triceratops, and Ornithomimus.
Let’s begin with the most famous dinosaur of all, the Tyrannosaurus Rex! If you’ve seen a skeleton of a T-Rex at a natural history museum, then you probably remember their sharp teeth. Because the T-Rex was a carnivore, they needed teeth that could tear through their prey. The T-Rex’s front and side teeth were serrated so that they could easily grip, pull, and rip their food. Their back teeth were wider and duller for chewing and additional gripping power, even when their prey was struggling to get away. Beyond their mouth of impressive teeth, the T-Rex is also known for having small arms. However, its arms were not needed to catch and eat prey because its bite was so powerful.
In contrast to the imposing figure of the T-Rex, the Velociraptor was a tiny carnivorous dinosaur, roughly the size of a small turkey. But that doesn’t make their teeth any less sharp! The Velociraptor had anywhere from 27 to 30 serrated teeth that were spaced apart in their upper and lower jaws. Its combination of sharp teeth and deadly claws were ideal for scavenging and hunting smaller dinosaurs, reptiles, and amphibians.
The Brachiosaurus had thick jawbones and spoon-shaped teeth. As herbivores, they fed on a variety of vegetation, including cycads, gingkos, and coniferous trees, consuming about 880 pounds of plant matter every day! It is believed the Brachiosaurus swallowed plants whole because its dentition was not equipped to break apart the plants, just strip them.
Like the Brachiosaurus, the Triceratops was an herbivore. Its beaky mouth was perfect for plucking and grasping plants, such as shrubs, ferns, palms, and cycads. Interestingly, the Triceratops had up to 800 teeth over the course of lifetime. These teeth were arranged in groups of about 40 columns, with each column consisting of about five teeth that were constantly replenished. That’s a lot of teeth for dinosaur!
An omnivore, the Ornithomimus ate both plants and animals. While some omnivorous dinosaurs had both sharp and flat teeth, dinosaurs like the Ornithomimus didn’t have any teeth. Instead, they used their long beaks like scissors to chop food up into manageable pieces.
