Are Platypus related to dinosaurs?
“Chilesaurus can be considered a ‘platypus’ dinosaur because different parts of its body resemble those of other dinosaur groups due to mosaic convergent evolution,” study author Martín Ezcurra of the University of Birmingham said in a statement.

How many teeth does a duck-billed dinosaur have?
With broad jaws bearing as many as 1,400 teeth, hadrosaurids were previously thought to have chewing surfaces similar to other reptiles, which have teeth composed of just two tissues — enamel, a hard hypermineralized material, and orthodentine, a soft bonelike tissue.
Where did duck-billed dinosaurs live?
The “duck-billed” dinosaurs. The “duckbilled dinosaurs” were common in the Upper Cretaceous of Europe, Asia, and North America. They were members of the Ornithopoda, and close relatives and possibly descendants of the earlier iguanodontid dinosaurs.
How tall is a duck-billed dinosaur?

Diet: Hadrosaurus was an herbivore (a plant-eater). It had a toothless bill but many cheek teeth. Anatomy: This ornithischian dinosaur was 23 to 32 feet (7-10 m) long. It had a bulky body, a stiff tail and four legs.
Is the duck-billed dinosaur a herbivore?
It was a herbivorous dinosaur, eating plants. Its skull permitted a grinding motion similar to chewing. Its teeth were continually replacing and packed into dental batteries with hundreds of teeth. It used its duck-billed beak to crop plant material.
Is a duck a dinosaur?
Actually, birds are considered living dinosaurs. That’s why scientists sometimes call birds “avian dinosaurs.” Extinct dinos are “non-avian dinosaurs.” But although lots of birds split their time between water and land, H. escuilliei is the only non-avian dinosaur scientists have found that likely did so, too.
What dinosaurs had 500 teeth?
NigersaurusNigersaurus had a delicate skull and an extremely wide mouth lined with teeth especially adapted for browsing plants close to the ground. This bizarre, long-necked dinosaur is characterized by its unusually broad, straight-edged muzzle tipped with more than 500 replaceable teeth.
Which dinosaur has the most teeth?
HadrosaursHadrosaurs, or duck-billed dinosaurs, had the most teeth: up to 960 cheek teeth!
What is the largest duck-billed dinosaur?
EdmontosaurusEdmontosaurus included some of the largest hadrosaurid species, measuring up to 12 metres (39 ft) long and weighing around 4.0 metric tons (4.4 short tons).
