After picking its victim, the T-rex charges, but the Triceratops finds it just in time and turns away to face the hungry killer. The T-rex seizes the horn of the Triceratops and breaks it off. The herbivore tries to retreat again, but the T-rex chomps on his frill. After making a loud charge, the Triceratops slashes one of his horns into the T ...
Triceratops (/ t r aɪ ˈ s ɛr ə t ɒ p s / try-SERR-ə-tops; [1] lit. ' three-horned face ') is a genus of chasmosaurine ceratopsian dinosaur that lived during the late Maastrichtian age of the Late Cretaceous period, about 68 to 66 million years ago in what is now western North America.

Ankylosaurus [nb 1] is a genus of armored dinosaur. Its fossils have been found in geological formations dating to the very end of the Cretaceous Period, about 68–66 million years ago, in western North America, making it among the last of the non-avian dinosaurs. It was named by Barnum Brown in 1908; it is monotypic, containing only A ...
Thyreophora was defined as a clade by Paul Sereno in 1998, as "all genasaurs more closely related to Ankylosaurus than to Triceratops". Thyreophoroidea was first named by Nopcsa in 1928 and defined by Sereno in 1986, as " Scelidosaurus , Ankylosaurus , their most recent common ancestor and all of its descendants". [ 6 ]
The "dueling" inference comes from the numerous injuries sustained by both dinosaurs, including a tooth from the tyrannosaur embedded within the Triceratops, although it is not known whether they were actually buried fighting one another. Tyrannosaurus rex (Tyrant Lizard King) was a 40 ft. long carnivore weighing 10 tons and ruled the ...

Mounted skeletons of Tyrannosaurus (left) and Apatosaurus (right) at the AMNH. Dinosaurs are a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago, although the exact origin and timing of the evolution of dinosaurs is the subject of active research.
