Fascinating Facts: Which Dinosaurs Had the Most Teeth?
Dinosaurs existed in many shapes and sizes, each standing out due to its fascinating features. While we often look at easy-to-spot physical features, such as their size or body shape, we can also look at dental records. Read on to find out which dinosaurs had the most teeth!
The Beast With the Most Teeth
One beast stands out among the many dinosaur species due to its dental records and, more importantly, how many teeth it had. The Hadrosaurs was a duck-billed dinosaur with over 900 teeth! This herbivorous dinosaur lived during the Cretaceous period in what is now North America.
Similar to many animals we see today, the Hadrosaurus’s front teeth were sharp, allowing it to grab plants. Its back teeth, molars, or cheek teeth were flat, just like ours, allowing it to mash up the plants it ate.
Another fascinating fact about the dinosaur with the most teeth is that this beast’s teeth were packed closely together, and it continuously lost and regrew teeth. This means there was a continuous cycle of losing and regrowing teeth; the dinosaur would lose broken or worn-down teeth.
Dino Fun Fact
Unlike many species we see today, all Hadrosaurs did not have the same number of teeth; some had slightly more or less than others.
Which Dinosaur Had the Biggest Teeth?
The Hadrosaurus may have had the most teeth, but the T. rex had the largest, with some measuring 12 inches long and 20 inches thick! Large teeth allowed the King of Dinosaurs to devour prey with ease.
T-rex’s teeth were serrated and curved, designed to rip through flesh easily. With its powerful bite force of 8,000 pounds per square inch, the T. rex was a formidable predator!
What Do Dinosaur Teeth Tell Us?
Teeth can tell us quite a bit about prehistoric animals. Most herbivores had more variation in their teeth than carnivores; plant-eaters had flat and sharp teeth, while many carnivorous dinosaurs had serrated teeth. Dental records show key differences between species and, more importantly, what they ate.
For example, T. rex needed sharp, serrated teeth to shred and devour meat, while the Hadrosaurs had to mash up the leaves and grass they grazed on.
