There are a few reasons why dinosaurs have horns.
Defense. They have to be able to defend themselves in case of an attack.
To look fierce and vicious to scare off predators.
To make other dinosaurs be scared to keep them away from themselves.
Helpful tools when roaming or moving something.
There are other things, but those are the things I know.
-----------Edit
Current theories are that dinosaurs used them for aggressive displays to ward off competitors or to attract mates, much as animals with horns do in modern times. This is a convergent evolutionary theory.
However, in days past, it was believed that the horns were probably used for defense or attacking. This is considered highly unlikely because of the lack of serious damage to fossil remains that would be caused by this behavior.
about 10 feet long
i dont know but i think they use them to frighten other animals/creatures
An ancient mammoth that I do not know about.
They used their tusks as tools
Elephants are less hairy than mammoths and do not posses such large tusks. Elephants are not extinct, while mammoths are.
1. All mammoths had long, dramatically curved tusks. 2. All mammoths had longer forelimbs than hind limbs. 3. All mammoths were grazers.
Mammoths became extinct from people hunting them for their tusks and fur.
There are mammoth tusks that have been preserved. In fact, there was a trade of mammoth ivory from carcasses even after they were long extinct.
Their tusks are teeth; the second set of incisors become the tusks. They are used for digging for food, for fighting during mating season, and for defense against predators.
Woolly Mammoths ate kfc, McDonald's, unicorns, people, dinosaur's, plastic, atomic bombs, broken glass, metal, airplanes, their legs and their tusks
Mammoths are not the ancestors of the modern elephant. Mammoths had hairy coats and large tusks. The Woolly Mammoth was about 11 feet tall and weighed 6 to 8 tons.
Yes, some tusks are hollow; and no, some aren't. For example, the tusks of elephants, hippopotamuses, mammoths, walruses, and whales are mostly solid. But the narwhal tusk is hollow, as is that of the wild boar for much of its length.
