Print gives a blank worksheet, and the colored answer key on page 2 when that box is ticked. Colors you fill in on screen stay on screen. By keyboard: the arrow keys move around the grid, Enter colors a square, a digit colors it by that number and Backspace clears it.

How it works

Each color by number dinosaur here has its name on the sheet: Tyrannosaurus, Triceratops, Stegosaurus, Brachiosaurus, Ankylosaurus and Spinosaurus, plus a Pteranodon and a Hatching egg. Each is a pixel picture in two grid sizes.

A different crayon for each one

The Tyrannosaurus is brown, the Triceratops orange, the Stegosaurus green, the Brachiosaurus blue, the Ankylosaurus yellow and the Spinosaurus purple. Those colors are ours: nobody knows what color the animals were. The easy Brachiosaurus needs only 3 crayons, blue, black and green.

Shortest and longest sheets

The Pteranodon is the quickest at both sizes, 55 squares on the easy grid and 204 on Detailed 24 by 24. The detailed Spinosaurus and the detailed Hatching egg are the longest at 418 squares each.

  • Triceratops means three-horned face. Seen from the side, the sheet shows two of the three: ask pupils to find them.
  • Stegosaurus had upright plates along its back and spikes on its tail; ours has orange plates and yellow spikes.
  • Each easy grid but the Hatching egg has exactly one black square, the eye. Find it first.

Questions and answers

Is a Pteranodon a dinosaur?

No. Pteranodon was a pterosaur, a flying reptile, and pterosaurs were not dinosaurs. It is in this set as the one animal in the air, and its description on the page says what it was.

Which dinosaurs are in this set?

Six: Tyrannosaurus, Triceratops, Stegosaurus, Brachiosaurus, Ankylosaurus and Spinosaurus. The other two pictures are a Pteranodon and a baby dinosaur hatching from an egg.

Does each dinosaur color by number printable carry its name?

Yes. Each sheet is headed with its name, such as Color by number: Ankylosaurus, so pupils see how it is spelled. Uncheck Picture name on the sheet under More options and the heading says Mystery picture instead.

How this list was compiled: Our own pixel pictures, drawn square by square for this site on 12 by 12 and 24 by 24 grids in October 2026. Nothing is traced, scanned or copied from clip art, no picture shows a brand or a logo, and none shows a character from a film, show, book or game. The colors are our own choice: nobody knows what color these animals were. The one fact in each named animal's description was checked against Wikipedia and a museum's dinosaur pages in October 2026, and the color and square counts were counted from the finished grids.
