Why Kids Love This Roaring T-Rex

This T-Rex isn’t trying to scare anyone – he’s roaring because he’s having the best day ever. His raised arms look like he’s cheering, and kids usually can’t resist cheering along. The big body and round rock give little hands plenty of room to color without fiddly details. And that wide, toothless mouth is just begging for a bold splash of red or pink.

Fun Facts About Tyrannosaurus Rex

Tyrannosaurus rex lived at the very end of the Cretaceous period, about 68 to 66 million years ago, in what is now North America. At up to 40 feet long, it was about as long as a school bus. Its name means “tyrant lizard king.” T-Rex was a meat-eater with one of the strongest bites of any land animal we know of. Here’s a fun twist: nobody knows exactly what it sounded like, and some scientists think it made deep, rumbling sounds rather than a big roar.

What to Do With Your Finished T-Rex

Cut out your T-Rex and his rock, glue them onto cardboard, and you’ve got a dino desk buddy. Add a big speech bubble – what is he shouting about? Then hold a family roaring contest where the silliest roar wins!

Color Ideas for Your Roaring T-Rex

Go realistic or totally wild – here are a few ideas:

🟢 Classic green
Deep green with a lighter belly looks straight out of a dino book.
🟠 Sunny orange
Orange matches his cheerful mood perfectly.
🪨 Stone gray
A gray or brown rock makes your dino really pop.
❤️ Red mouth
Red or pink turns that big open mouth into the star of the page.
💡 Coloring Tip: Color the body and rock in light shades first, then add a darker tone under the belly and along the edge of the rock for an easy 3D effect.
