Dinosaur Teeth
Paleontologists are the scientists that love to study dinosaurs, and they learn a lot from dinosaur teeth. When analyzed along with the size of a dinosaur skull, a paleontologist can determine many things, including how the beast obtained its food and what sorts of things it ate. Some dino teeth even explain how the animal digested what it devoured.
Some dinosaurs had long teeth that were set in their jaws like the tines of a rake. These kinds of dinosaur teeth were used to pull nutritious leaves and bark from ancient plants. Other sorts of dinosaurs had razor sharp teeth that they used to kill and eat other animals, including other dinosaurs. Many herbivorous, plant-eating dinosaurs had rows of flat grinding teeth that they used to smash vegetable matter before swallowing.
Amazing facts about dinosaur teeth
1. Dinosaurs could re-grow any teeth that went missing. Paleontologists think that both plant-eating and carnivorous dinosaurs had the amazing ability to generate new teeth whenever they needed replacing a missing tooth. Dinosaurs such as Diplodocus may have grown brand new teeth every 35 days or so. Another dino, the Camarasaurus, required around two months to generate a replacement tooth, explains Live Science magazine.
2. A funny looking, duck-billed dinosaur named Hadrosaur boasted more teeth in its mouth than any other dinosaur that has ever been discovered. Although Hadrosaurs probably dined upon nothing but plant materials, they used almost 1,000 self-sharpening teeth to do make it happen.
3. The Apatosaurus dinosaur had a whole lot of teeth in its jaws, but it was not able to chew its food. Instead, the Apatosaurus dinosaur had specialized “stripper teeth” that were utilized to scrape leaves from vegetation. Fossil evidence discovered over the years indicates that the massive 19-ton reptilian beast probably swallowed without chewing its food at all.
4. Tyrannosaurus rex teeth had a mouth full of serrated teeth. The mighty dino's curved, chisel-like front teeth were used to grip, pull and yank raw meat from the bones of its unfortunate prey. Back teeth were not molars like we know today, but they did serve to dice meat into chunks that could be easily swallowed. Amazingly, some rather "banana-shaped" T. rex teeth were a foot long, including several inches of root. T. rex boasted 60 teeth in its Volkswagen-sized skull. Its front teeth were more closely spaced than the teeth toward the back of T. rex's massive mouth.
5. Kentrosaurus, Stegosaurus, and other Stegosaurids had dinosaur teeth attached to a jaw that probably wasn't very strong. These ancient beasts primarily dined upon low-lying shrubs, mosses, and fallen fruit.
6. Trachodon, Deinodon, and Cardiodon dinosaurs left no bones to be discovered (yet) but since teeth are harder, they did leave their dental imprint on the fossil record.
