Spinosaurus is the biggest carnivorous dinosaur ever discovered — longer than a T-rex, with those dramatic sail-like spines running the length of its back. These coloring pages take that imposing animal and give it a complete personality transplant. The spinosaurus here are round-bodied, big-eyed kawaii characters: some are wearing costumes, some are mid-adventure, some are doing things that no self-respecting apex predator would have done 95 million years ago. The sail on the back is still there on most pages, which gives young colorers something distinctive to work with.
A few pages in the set take a different approach — busier compositions with multiple dinosaurs or detailed action scenes that give older kids more to navigate. The mix across 21 pages means there’s something for a quick coloring break or a longer focused session. Everything here is free to download and easy to print.
Free Printable Spinosaurus Coloring Pages
This collection includes 21 printable spinosaurus coloring pages featuring kawaii-style cartoon spinosaurus in various poses, costumes, and adventure scenes. Some pages are simple upright portraits; others include multi-dinosaur action compositions with detailed backgrounds. Each page is sized for US Letter and A4 paper and downloads as a ready-to-print PDF.
Who Are These Spinosaurus Coloring Pages Best For?
Kindergarteners will find the simpler upright-pose pages very manageable. The body shapes are broad and easy to fill, and the sail fin on the back gives a distinctive shape to color separately from the main body — which is exactly the kind of obvious structural division that helps younger kids organize their coloring. Pages with a single spinosaurus against a plain background are the ones to hand a five-year-old first.
Early-elementary kids get more from the pages with accessories, costumes, and multi-dinosaur action scenes. The busier compositions require planning — choosing colors for both the spinosaurus and the props, deciding how to handle background elements — which keeps a 6- or 7-year-old engaged longer than a simple silhouette. The action scenes in particular reward a slow, careful approach.
In a classroom setting, this set works well alongside a Cretaceous period unit or a general dinosaur study. Having 21 pages gives every student in most class sizes a different design, and the range from simple to complex means differentiated options without any extra preparation.
Interesting Spinosaurus Facts to Share While Coloring
Spinosaurus is the largest known carnivorous dinosaur. Estimates put it at 46–59 feet long — significantly longer than T-rex. It was discovered in North Africa and lived approximately 95–100 million years ago during the Cretaceous period.
The spine sail on its back could reach six feet tall. What those spines were for is still debated. Current thinking favors a hump-like fat storage structure rather than a flat sail, but the dramatic spines — the animal’s defining feature — are not in dispute.
Spinosaurus was primarily a fish eater. Its snout was long and narrow like a crocodile’s, its nostrils were set back so it could breathe with its face in water, and isotope analysis of its bones places it in aquatic environments. It probably waded, swam, and hunted like a giant heron.
It walked on all fours at least part of the time. For decades spinosaurus was reconstructed as a biped like T-rex. More complete fossils suggest it spent significant time on all four limbs, particularly in water — which rearranged a lot of museum displays and textbook illustrations.
The original spinosaurus fossils were destroyed in World War II. They were discovered in Egypt in 1912, sent to a museum in Munich, and then bombed during the war in 1944. Everything known about spinosaurus today comes from subsequently discovered specimens and reanalysis of surviving casts and descriptions.
Creative Spinosaurus Coloring and Craft Ideas
Sail Color Theory Some scientists think the sail was brightly colored for display, like a peacock’s tail. Color the spinosaurus body a realistic dark green, then go wild with the sail — stripes, spots, gradients — and explain that this is actually a plausible scientific guess.
Aquatic Scene Background Color the spinosaurus, then add a river or lake background behind it — reeds, water ripples, a fish in the water. The setting is more scientifically accurate than a dry land scene.
Size Comparison Drawing Draw a rough outline of a school bus next to the colored spinosaurus at the same scale. A full-grown spinosaurus was about the length of two buses end-to-end.
Costume Character Story Pick the spinosaurus with a costume and write a three-sentence story about what it’s doing. Who is Spinosaurus Sam? Where is he going? What’s in the backpack?
Dino vs. Dino Comparison Color a spinosaurus page and a T-rex page side by side, then list three physical differences (snout shape, arm length, body posture). Use the coloring session as the starting point for a research comparison.
Lost Fossil Scene Color the spinosaurus, then cut it out and paste it onto a drawing of a bombing scene or a museum — as a nod to the original fossils destroyed in World War II. An unusual history lesson that sticks.
Hump vs. Sail Vote Look up the two main theories about what the spines were for (display sail vs. fat hump) and have kids vote on which they find more convincing before coloring. Color the spines based on whichever theory they chose.
How to Print These Spinosaurus Coloring Pages
Each page downloads as a PDF sized for US Letter and A4 paper — no adjustment needed. Standard copy paper works well for crayons and colored pencils. For markers or felt tips, 90gsm paper prevents bleed-through. The action scenes with finer detail lines benefit from keeping “fit to page” scaling off in your print settings.
