Both Protoceratops and Triceratops belong to the suborder Ceratopsia, so they are somewhat related. However, Protoceratops belongs to the family Protoceratopsidae while Triceratops belonged to the family Ceratopsidae.
There were many types of dinosaurs who are believed to have traveled in packs or herd. Some of them include the Styracosaurus, Protoceratops, and the Triceratops.
Velociraptor was a small, carnivorous dinosaur. As such, it would have hunted small prey such as lizards and mammals all the way up to animals as large as Protoceratops. We have proof of Velocraptor hunting Protoceratops because there is a fossil of a Velociraptor and a Protoceratops that died mid combat.
First Horned Face - Direct translation from Latin. Another example of this type of naming is Triceratops meaning Three Horned Face
Protoceratops is older, having existed between 75 and 71 million years ago. Triceratops existed at the very end of the Mesozoic, from 68 million years ago to the extinction event 65.5 million years ago.
Rhinoceros is not at all related to Triceratops. Rhinoceros is a mammal, while Triceratops is a dinosaur and thus a reptile. Any similarity between the two is simply superficial.
Protoceratops belongs to the Ceratopsidae family, which is further divided into subfamilies such as Protoceratopsinae and Ceratopsinae. These subgroups are based on differences in skull anatomy, size, and other characteristics among different species of Protoceratops and related dinosaurs.
There could be some.
Protoceratops did not have prey. It was an herbivore.
Triceratops didn't have any descendants. Their closest living relatives are the birds, which evolved from theropod dinosaurs. All birds are equally related to Triceratops.
The only ones of which I am aware where eggs of Protoceratops, a very earl, dog-sized ceratopsian dinosaur, a progenitor of the huge upper Cretaceous ceratopsians such as Styracosaurus and Triceratops.
Roy ChapmanAndrews named the protoceratops.
Protoceratops had many predators, such as Oviraptor and Velociraptor.
