Dinosaur Name Generator
Real dinosaur species names, randomly served
Generate real dinosaur genus names, from household names like Tyrannosaurus and Triceratops to lesser-known giants like Dreadnoughtus and Patagotitan. Handy for paleontology fans, teachers, worldbuilders, and anyone picking a favorite dinosaur.
About dinosaur names
Every dinosaur name is a genus in binomial (Linnaean) nomenclature, built mostly from Greek and Latin roots. The suffix -saurus means lizard, -raptor means thief or plunderer, -ceratops means horned face, -mimus means mimic, and -venator means hunter. The front half usually describes a feature (Tri-ceratops, three-horned face; Pachy-cephalo-saurus, thick-headed lizard), a place (Alberto-saurus, Utah-raptor, Patago-titan), or a person (Leaellyna-saura, named after paleontologist Tom Rich's daughter). Some borrow local languages, like Tarchia (Mongolian for brainy) and Zhuchengtyrannus.
The 1,000 names here are all real genera, spanning the Triassic (Eoraptor, Herrerasaurus, Coelophysis) through the late Cretaceous (Tyrannosaurus, Triceratops, Ankylosaurus). They cover the major groups: theropods from Compsognathus to Giganotosaurus, long-necked sauropods including record holders Argentinosaurus and Dreadnoughtus, armored ankylosaurs and stegosaurs, horned ceratopsians, duck-billed hadrosaurs, and dome-headed pachycephalosaurs. The list also runs deep into titanosaurs such as Notocolossus and Diamantinasaurus, whip-tailed diplodocoids, iguanodontians, and small early ornithischians such as Fruitadens. Names that were later sunk into other genera, such as Seismosaurus, are left out; Brontosaurus is included because a 2015 study restored it as a valid genus.
Use the list to pick a study subject, seed a worldbuilding bestiary, name a Jurassic World Evolution exhibit, or find a lesser-known favorite beyond the usual T. rex.
How to choose dinosaur names
- Read the roots: -raptor and -venator names are usually fast predators, -ceratops names are horned herbivores, and titan-, -titan, or giga- names signal enormous sauropods or carnivores.
- For a fictional dinosaur, coin a name the same way scientists do: descriptive Greek/Latin root plus -saurus, -raptor, or -ceratops, or a place name plus -saurus (e.g. a dinosaur found in Devon could be Devonosaurus).
- Want a scary but obscure pick for a story or game? Try Lythronax ('gore king'), Skorpiovenator, Tyrannotitan, or Teratophoneus ('monstrous murderer') instead of the well-worn T. rex.
- For classroom or trivia use, note that some famous 'dinosaurs' are not dinosaurs: Pteranodon and Quetzalcoatlus are pterosaurs, Mosasaurus and Plesiosaurus are marine reptiles, and Dimetrodon is a synapsid that lived before dinosaurs existed.
Frequently asked questions
Are all of these real dinosaurs?
Yes. Every name is a published dinosaur genus, from famous ones like Stegosaurus to recent discoveries like Dakotaraptor and Regaliceratops. Only genuine dinosaurs are listed, so pterosaurs and marine reptiles are not included.
How are dinosaurs named?
The scientist who describes a new dinosaur chooses a genus and species name under the International Code of Zoological Nomenclature, usually from Greek or Latin roots describing a feature, the discovery site, or a person being honored. The name becomes official once it is published in a peer-reviewed paper.
Why is Brontosaurus on the list if it was renamed Apatosaurus?
Brontosaurus was folded into Apatosaurus in 1903, but a 2015 study by Tschopp and colleagues found enough differences to restore it as a separate genus, so most paleontologists now treat both as valid.
Which dinosaur names are good for a fantasy world or game creature?
Shorter, punchy genera work best as creature names: Anzu, Khaan, Tawa, Balaur, Minmi, Dilong, and Rugops all sound invented but are real. Longer names like Carcharodontosaurus are better as species labels than character names.
