Illustration of specimen YPM 1871E, the horn cores that were erroneously attributed to Bison alticornis, the first named specimen of Triceratops. The first named fossil specimen now attributed to Triceratops is a pair of brow horns attached to a skull roof that were found by George Lyman Cannon near Denver, Colorado, in the spring of 1887. [3]
There is evidence for an aggressive interaction between a Triceratops and a Tyrannosaurus in the form of partially healed tyrannosaur tooth marks on a Triceratops brow horn and squamosal (a bone of the neck frill); the bitten horn is also broken, with new bone growth after the break
Ceratopsia or Ceratopia (/ ˌ s ɛr ə ˈ t ɒ p s i ə / or / ˌ s ɛr ə ˈ t oʊ p i ə /; Greek: "horned faces") is a group of herbivorous, beaked dinosaurs that thrived in what are now North America, Asia and Europe, during the Cretaceous Period, although ancestral forms lived earlier, in the Late Jurassic of Asia.
The horns above the eyes were forward-curving and have been estimated at 80 cm (2.6 ft) long. The lower base of these horns was narrow and vertically directed, which with Triceratops is a juvenile trait. Three bite marks can be observed above the eye, near the base of the left horn, which were interpreted as traces of scavenging.

A previously unknown species of dinosaur finally has a name five years after the horned specimen’s discovery in Montana: Lokiceratops rangiformis.
Triceratops (meaning 'three-horned face') was a herbivorous genus of ceratopsid dinosaur that lived during the late Maastrichtian stage of the Late Cretaceous Period, around 68 to 65 million years ago (mya) in what is now North America. It was one of the last dinosaurs to appear before the great Cretaceous–Paleogene extinction event.
Guard hair is more water resistant, and you will see water “beading up” on their fur if they get splattered. But Wait, There’s Four! Some cats have more down hair than other kinds, and so ...
