Tyrannosaurus rex didn't choose to hunt Triceratops over other animals. The most common herbivores at that time and place were Triceratops and Edmontosaurus. Tyrannosaurus definitely hunted Edmontosaurus regularly, probably more often than Triceratops.
The dinosaur with three horns is called the "Triceratops". It is a large plant eater with a frill protecting it's neck. The Triceratops uses the horns for spearing plants, and as weapons to protect itself from predators.
There were only two species of Triceratops. They were Triceratops horridus and Triceratops prorsus.
No. A triceratops is a dinosaur.
The triceratops was first discovered by American paleontologist Othniel Charles Marsh in 1887. Marsh unearthed the first fossils in the Hell Creek Formation of Montana, which he later named Triceratops horridus. This discovery was part of the "Bone Wars," a period of intense scientific rivalry between Marsh and Edward Drinker Cope. The triceratops has since become one of the most recognized dinosaur species in popular culture.
Yes - Triceratops was an herbivore.
The triceratops lived in Argentina.

Rhinos only bear a passing resemblance to Triceratops because of their bulky bodies and the horns on their faces. They are not related to Triceratops, however. Rhinos are mammals, while Triceratops were dinosaurian reptiles. No mammals have evolved from dinosaurs, rhinos included. In short, they appear slightly similar just because of coincidence.
