How do dinosaurs get their names?
Giving any living or extinct organism a scientific name is governed by a set of rules called the International Code of Zoological Nomenclature, and paleontologists who name dinosaurs must follow those rules to make the name valid. Although this process may seem unnecessary, it is extremely important in making sure that all paleontologists understand what kind of dinosaur is being referred to when a name is used.
The code requires that a scientific name be composed to two parts. The first part, called the genus, is always capitalized; the second, called the species is never capitalized. Both names are always italicized, and sometimes the genus name is abbreviated (as in T. rex for Tyrannosaurus rex). The genus name may be used alone to refer to all the species in a particular genus.
Key characteristics
The first person to describe a new kind of dinosaur assigns the animal its name, and these names are often derived from Greek or Latin words. Many names reflect key characteristics of the animal, such as the place the specimen was collected, the person who collected the fossil, or one of the animal's unusual anatomical characteristics.
The new name is based on one particular fossil, which is called the type specimen, and this type specimen must be complete enough to exhibit features that clearly distinguish it from all other species. Any specimens discovered later that are thought to belong to the new species must be found to have no significant differences with the type specimen.

- What colors were the dinosaurs?(5 votes)
- Paleontologists don't know for certain what color any of the dinosaurs were. They do have several theories, though. For example, many believe that dinosaur skin was probably drab shades of gray or green, allowing them to blend into their surrounding environments. No good specimens of skin have been properly fossilized, but I bet there will be a scientific breakthrough about the color of dinosaurs in the future.(6 votes)

- Duh. It has three horns on his face. That was really self-explanatory.(3 votes)
- person who discover first dinosaur(1 vote)
- The first dinosaur to be described scientifically was Megalosaurus in 1824, by William Buckland. Buckland (1784-1856) was a British fossil hunter and clergyman who discovered some Megalosaurus fossils in 1819 and named the reptile in 1824.(2 votes)
- how do you think dinosaurs get their names(1 vote)
- the paleontologists get the fossils and they need to know what kind of dinosaur is being referred to when a name is used(2 votes)
- why are dinosaurs not alive today
.(2 votes)- birds are dinosaurs, and also you might want to search up the hoatzin bird, it has wing claws and to answer ur question, all went exctinct(0 votes)

- what does bronchiasaurus mean(1 vote)
- brachiosaurus means "arm lizard". Brachio- comes from the latin word "bracchium", which means "arm". Saurus, as you know, means "lizard".(1 vote)
