How this list was compiled: The choice of the 206 dinosaurs and every line are our own. Checked 2026-09-18, and the corrected cards again on 2026-09-19, against two live sources: the Natural History Museum Dino Directory (https://www.nhm.ac.uk/discover/dino-directory/, one page per dinosaur, saved with each item as src) and the English Wikipedia article for the same dinosaur (https://en.wikipedia.org/wiki/ followed by the name, saved as wiki). Every name was also checked against Wikipedia's List of dinosaur genera (https://en.wikipedia.org/wiki/List_of_dinosaur_genera). A period such as Late Cretaceous is shown in full only where both sources agree; where they differ the card gives the period alone. Two cards are exceptions, because the museum page is out of date: Jobaria (Middle Jurassic) and Supersaurus (Late Jurassic) follow their Wikipedia articles, which cite the newer dating of the rocks. Where the two sources gave different countries or name meanings, the card follows the Wikipedia article and its cited paper: Gigantoraptor was found in Inner Mongolia, which is part of China, Torosaurus means perforated lizard and Plateosaurus most likely means broad lizard. Lengths are the museum's figure, or the range in the Wikipedia article where the two were more than about a fifth apart. Ten newer finds that the museum directory does not list were checked against Wikipedia alone. Period dates in the page text follow the International Commission on Stratigraphy chart as quoted on Wikipedia's Triassic, Jurassic and Cretaceous articles. The 23 dinosaurs with no name meaning on the card carry one other fact instead (x.fact), each read in the genus's English Wikipedia article (the x.wiki address, or x.src where that is the Wikipedia page) on 2026-09-19.

How it works

All 206 dinosaurs are real, from Archaeopteryx at about half a metre to Supersaurus at about 35 metres. Press Pick 5 new dinosaurs: each card says when it lived, what it ate, how long it grew and where it was found.

Read the full guide

Period first, then diet and size

The menu under the button reads Any period. Change it to Triassic (about 252 to 201 million years ago), Jurassic (201 to 143) or Cretaceous (143 to 66). Here 136 dinosaurs are Cretaceous, 60 are Jurassic and only 10 are Triassic. The next menu sets the diet, and size buttons are under More filters: Jurassic with Meat-eaters leaves 19. Eoraptor and Massospondylus, whose diet is still debated, appear only under Any diet.

A dinosaur randomizer for a size line-up

Line the five up from shortest to longest. To guess first, press Hide all facts. Press Show fact on a card to bring its line back.

Say a long name in parts: Pachy, cephalo, saurus. The whole name means thick-headed lizard.
Under More filters press Giants, 15 m and up, draw one and pace it out. Diplodocus is about 26 metres: 26 big steps.
To keep a favourite, take the others away with × and press again. Then press Print for a wall chart with facts.

Questions and answers

Does the random dinosaur generator only pick real dinosaurs?

Yes. In September 2026 every name was checked against Wikipedia's list of dinosaur names, and all but ten against the Natural History Museum's Dino Directory. Pteranodon and Mosasaurus were not dinosaurs, so they are in the random extinct animal generator.

Why does my book give a different length?

A length runs nose to tail and is worked out from the bones there are, so experts differ. Most cards show the museum's figure, or a range where Wikipedia differs from it by more than about a fifth. Argentinosaurus reads about 30 to 35 metres.

Are birds really dinosaurs?

Yes. Scientists class birds as living dinosaurs, the only ones left today. Archaeopteryx, one of the smallest here, had feathers and broad wings back in the Late Jurassic. For the living kind, try the random bird generator.
