Did any dinosaurs have frills?
Ceratopsian, also called ceratopian, any of a group of plant-eating dinosaurs from the Cretaceous Period (146 million to 66 million years ago) characterized by a bony frill on the back of the skull and a unique upper beak bone, called a rostral. Yinlong downsi Encyclopædia Britannica, Inc.
Did any dinosaurs have neck frills?
Many dinosaurs had distinctive bony frills around their necks – the best-known being the distinctive Triceratops. It’s not a feature found in living animals today, and paleontologists have long debated what the function was of the diverse array of frills and horns in this family of dinosaurs, called ceratopsians.
Why did dinosaurs have head frills?
Their “beak” and rows of grinding cheek teeth suggest that they fed on tough vegetation. The huge, heavy “frill” of ceratopsians such as Triceratops may have served as armor against the attacks of saurischian predators like Tyrannosaurus, which lived in the same time and place as Triceratops.
What is the frill on a dinosaur?
A neck frill is the relatively extensive margin seen on the back of the heads of reptiles with either a bony support such as those present on the skulls of dinosaurs of the suborder Marginocephalia or a cartilaginous one as in the frill-necked lizard. … The feature is now referred to as the parietosquamosal frill.
What animal alive today is bigger than a dinosaur?
The largest arthropod still living today is the Japanese spider crab. This one is small-fry compared to a whopper caught in 1921 which had an arm-span of 3.8 metres. Blue whales are the largest animals ever to have lived. They are bigger than even the largest of the dinosaurs.
Which was the biggest dinosaur?

Is Dilophosaurus a raptor?
Dilophosaurus was one of the earliest large predatory dinosaurs, a medium-sized theropod, though small compared to some of the later theropods. It was also the largest known land-animal of North America during the Early Jurassic.
When did dinosaurs go extinct?

How did triceratops go extinct?
Sixy-six million years ago—about three million years after the dinosaur first appeared—a 7.5-mile-wide asteroid slammed into Mexico’s Yucatán Peninsula. The subsequent environmental catastrophe killed off more than three-quarters of all species on the planet, including Triceratops and its fellow non-avian dinosaurs.
What dinosaur has 2 horns?
Triceratops has captured the public imagination ever since the first fossils were discovered in 1887. But it’s hardly the only horned dinosaur that once roamed the Earth. Meet the two-horned zuniceratops, oldest of the American relatives of triceratops.

What is a dinosaur with one horn?
Styracosaurus was a genus of herbivorous ceratopsian dinosaur from the Cretaceous, about 76.5 to 75 million years ago. This is a type of dinosaur that somewhat resembles a Triceratops. However they have only one horn, the one on their nose that is longer than those of a Triceratops.
