The sturdy nature of the animal's skull has ensured that many examples have been preserved as fossils, allowing variations between species and individuals to be studied. Triceratops remains have subsequently been found in Montana and South Dakota (and more in Colorado and Wyoming), as well as the Canadian provinces of Saskatchewan and Alberta.
One individual might represent the "type specimen" of a particular species. This species would in turn represent the "type species" of a particular genus, unless it is referred to a previously described genus. Most dinosaur genera are monospecific, therefore most type specimens are also the type species of their respective genera.
Ceratopsidae (sometimes spelled Ceratopidae) is a family of ceratopsian dinosaurs including Triceratops, Centrosaurus, and Styracosaurus. All known species were quadrupedal herbivores from the Upper Cretaceous. All but one species are known from western North America, which formed the island continent of Laramidia during most of the Late ...

Unlike almost all other dinosaur groups, skulls are the most commonly preserved elements of ceratopsian skeletons and many species are known only from skulls. There is a great deal of variation between and even within ceratopsian species.
They further noted that the holotype specimen, nicknamed "Frederik", represents one of the first distinct dinosaur species to be displayed in the country. [ 2 ] [ 3 ] In 2024, an international team of researchers led by Mark A. Loewen and Joseph J. W. Sertich published the description in PeerJ of Lokiceratops rangiformis as a new genus and ...
The latest dinosaur being mounted at the Natural History Museum in Los Angeles is not only a member of a new species — it's also the only one found on the planet whose bones are green, according ...
Styracosaurus (/ s t ɪ ˌ r æ k ə ˈ s ɔːr ə s / sti-RAK-ə-SOR-əs; meaning "spiked lizard" from the Ancient Greek styrax / στύραξ "spike at the butt-end of a spear-shaft" and sauros / σαῦρος "lizard") [1] is an extinct genus of herbivorous ceratopsian dinosaur from the Late Cretaceous (Campanian stage) of North America.
