Which dinosaurs had sharp teeth?
Tyrannosaurus rex had sharp, knife-like teeth. It used them to rip meat off its prey and swallow it whole. Triceratops had a whole battery of sharp teeth that it used to slice plants. Other dinosaurs, such as Hadrosaurs, had whole batteries of grinding teeth used to grind up plants.

Why are T rex’s teeth sharp?
rex’s teeth could crush bone. Its teeth have been found embedded in the bones of its prey and chunks of bone appear in its fossilized dung. “But the serrations were most efficient for piercing flesh and gripping it while ripping off a chunk of meat, called the ‘puncture and pull’ feeding style,” Brink said.
What is the biggest dinosaur tooth ever found?
The longest dinosaur tooth ever recorded belonged to a T. Rex, and they were a whopping 12 inches long! This measurement includes the tooth’s root though, so the exposed part of the tooth was 6 inches long.
What dinosaur has 960 teeth?
Hadrosaurs
Hadrosaurs (Edmontosaurus, Maiasaura, Lambeosaurus, Parasaurolophus and many more) were duck-billed dinosaurs and had around 960 self-sharpening cheek teeth; the most teeth of all of the dinosaurs.
Did T Rex have feathers?
Paleontologists think feathers may have first evolved to keep dinosaurs warm. But while a young T. rex probably had a thin coat of downy feathers, an adult T. rex would not have needed feathers to stay warm.
How many teeth did T Rex have?
This dinosaur used its 60 serrated teeth, each about eight inches long, to pierce and grip flesh, throwing prey into the air and swallowing it whole.
What dinosaurs lived in what periods?
Dinosaurs lived during three periods of geological time – the Triassic period (which was 252-201 million years ago), the Jurassic period (about 201-145 million years ago) and the Cretaceous period (145-66 million years ago). These three periods together make up the Mesozoic Era.
What was the life expectancy of a Tyrannosaurus rex?
28 years
These studies, done in conjunction with paleontologists at AMNH, document that that Tyrannosaurus, which attained a weight of more than 10,000 pounds as an adult, reached sexual maturity at about 20 years of age and lived for up to 28 years.
Did T rex teeth grow back?
T. rex had 50 to 60 thick, conical, and serrated teeth that were replaced after being broken. Due to their colossal size, T. rex teeth were reinforced and tightly knit to prevent breakage because the replacement process took about 2 years.
How big was a duck billed dinosaur?
Hadrosaurs (meaning “bulky lizards”) were the family of duck-billed herbivorous dinosaurs. They were the most common dinosaurs. Hadrosaurs ranged in size from 10 to 65 ft (3 to 20 m) long.
What kind of teeth did dinosaurs have?
The Apatosaurus, a large herbivore related to the Brontosaurus, had chisel-like teeth, but likely swallowed plants whole, without chewing. Some dinosaurs are only known from their teeth. Since dinosaur teeth are harder than bone, they fossilized more readily. The Trachodon, Deinodon, and Cardiodon dinosaurs only have teeth in the fossil record.
What was the name of the dinosaur with no horns?
Achelous was an obscure, shape-shifting river god of Greek mythology who had one of his horns torn off during a fight with Hercules. The name Achelousaurus refers both to this dinosaur’s supposedly “missing” horns and its weird, shape-shifting mix of frills and bony knobs, compared to its fellow ceratopsians. Agujaceratops.
Are there any differences between Tyrannosaurus rex teeth and other dinosaurs?
Not often present. Tyrannosaurus rex had approximately 60 robust serrated teeth that were wide and dull compared to the flat and dagger-like teeth of other carnivorous dinosaurs. These teeth varied in shape and purpose. The front teeth were closely packed, were more chisel-like that the rest, and were for gripping and pulling.
Did T Rex eat its own kind?
The T. Rex was not above eating its own kind. Tyrannosaurus Rex bones have been found with T. Rex tooth gouges, suggesting it may have been a cannibal. Hadrosaurs had the most teeth. Known as the duck-billed dinosaur, hadrosaurs had beaks and up to 1,000 cheek teeth that were used to break down tough vegetation.
