What’s the Value of a Real Dinosaur Tooth (Single, On Jawbone)?

Triceratops was a herding dinosaur and there were lots of them. Think Buffalo on Serengeti (or North American plains two centuries ago for that matter) but 66 million years ago. 2. There had lots of teeth, up to in their jaws at a single time. Triceratops' teeth have five layers of tissue, the researchers found. To put that in perspective, crocodiles' and other reptiles' teeth have just two layers: enamel over a core of dentine, a Estimated Reading Time: 4 mins.

Though scary, those massive teeth served a very integral purpose to the life of the dinosaur. By looking at the size, shape, curvature, wear, and numerous other details of teeth, scientists can discern not just what the dinosaur ate, but also intricacies on how it ate, and how it fit in with the other animals and plants how to negotiate vacation time with new job its ecosystem.

Triceratops: One of the Last Great Dinosaurs

Feb 19,  · Triceratops, large quadrupedal plant-eating dinosaur that had a frill of bone at the back of its skull and three prominent horns. Fossils date to the final 3 million years of the Cretaceous Period ( million to million years ago), making it one of the last of the non-avian dinosaurs to have . The triceratops' head is one of the largest of any land animal discovered. Some triceratops may have had as many as teeth! They are a member of the ceratopsia suborder of dinosaurs. It probably wasn't a very fast dinosaur. Dec 05,  · Within its beak tipped mouth the Triceratops could have anywhere from to teeth. The Triceratops was able to hold so many teeth within its jaw due to the fact that the teeth were arranged in columns (also called “batteries”) within the mouth and usloveescort.coms: 9.

Triceratops is known for its distinguished trio of horns, but the dinosaur's teeth are just as distinctive, a new study finds. An analysis of million-year-old Triceratops ' teeth shows they are more complex than reptilian teeth, and rival the complexity of chompers found in mammals' mouths.

The dinosaurs' teeth are so sophisticated that they actually transformed into knives of sorts while the beast was eating. Triceratops ' teeth have five layers of tissue, the researchers found. To put that in perspective, crocodiles' and other reptiles' teeth have just two layers: enamel over a core of dentine, a calcified tissue denser than bone, Erickson said. Horse and bison, once thought to have the most complex teeth of any animal, have four layers. Of the Triceratops ' five layers, the vasodentine — a layer of hard but porous dentine filled with blood vessels — is one of the most important.

Vasodentine is rare and hasn't been seen outside of bony fishes, the researchers said. As Triceratops chewed its food, the vasodentine wears over time "into this scalloped valley on the surface of the teeth. It's a lot like some chef knives you'll see.

These chompers were also an evolutionary advantage: They may have helped Triceratops eat a greater variety of plants, giving the species an advantage over other herbivorous dinosaurs , the researchers said. The scalloped valleys would have made slicing more efficient, and increased the pressure at the slicing edges so that the dinosaur could chew its food without putting too much force on its teeth, Krick said.

The valleys also would have reduced contact between the teeth and the dinosaur's leafy meals, reducing the amount of friction and making chewing more efficient, he said. Triceratops dinosaurs are hardly the only animals with self-wearing teeth. Many mammals but not really humans have teeth that change shape with use, Erickson said. For instance, the teeth of most herbivorous mammals wear down to create complex file surfaces that can mince plants, the researchers said.

Self-wear is less common in reptiles, which have pointy teeth. These animals usually use their teeth to seize or crush prey, not chew it, the researchers said.

To get a better look at the Triceratops ' teeth, a team of paleobiologists and engineers examined a few teeth from the species Triceratops horridus. Using a special tool called a microtribometer a machine that measures the friction and forces between two solid surfaces , the researchers made nanosized indentations in the teeth using a diamond-tipped microprobe.

These indentations helped the scientists identify the different layers on the teeth , as well as the chompers' hardness and wear resistance. The researchers created a computer model that showed, in 3D, how each tissue wore down and how the Triceratops developed their uniquely scalloped teeth. This model can also be used for industrial and commercial applications, Krick said.

Erickson and Krick previously worked together on duck-billed hadrosaurid teeth , finding that these herbivorous dinosaurs, which also lived during the Late Cretaceous, had six-layered teeth. Through this work, the researchers have learned that "dinosaur teeth are much more complex architecturally and biomechanically than we ever realized," Erickson said.
