Step-by-Step Instructions

1

Step 1: Prepare your rock

Wash and dry your rock thoroughly. Choose an oval or elongated shape that resembles a dinosaur body. Use a pencil to lightly sketch the outline of a simple T-Rex or triceratops shape on the rock.

2

Step 2: Paint the base color

Paint the entire dinosaur shape with green acrylic paint. Apply two coats for a solid, even color. Let each coat dry completely before adding the next one.

Step 3: Add details and texture

Using dark green or brown paint and your detail brush, add scales, spots, or stripes along the body. Paint short curved lines for scales or small dots for a spotted pattern. Add claws on the feet with dark paint.

Step 4: Paint the face

Add a white eye with a black pupil. Paint a smiling mouth with small white teeth showing. For a T-Rex, make the mouth wide and toothy. Add nostrils with two small dots.

Step 5: Add background and seal

Paint a yellow or orange belly on your dinosaur for contrast. Once everything is fully dry, apply clear sealant spray to protect your prehistoric friend from the elements.

Step 6: Add RoxGeo Code

On the bottom or back of your rock, write ROXGEO.COM followed by a slash and your rock’s unique code (e.g. ROXGEO.COM/ABC123). This lets the finder go directly to your rock’s profile page and log their discovery. If the rock is too small for the full address, write #ROX followed by the code without spaces (e.g. #ROXABC123) — it’s short, easy to search on Google, and leads straight to your rock’s journey page. Use a fine-tip permanent marker or acrylic paint pen, and seal it with clear varnish so the code stays readable through rain, sun, and adventure.

Helpful Tips

An elongated rock naturally looks like a dinosaur body — look for one with a slight curve.
Sketch the dinosaur shape with pencil first so you can adjust before painting.
Add spines or plates along the back for a stegosaurus look.
Use a toothpick to paint tiny teeth and claws with precision.
Try different dinosaur species on different shaped rocks for a collection.
For the RoxGeo code on the bottom, use a waterproof permanent marker (like Sharpie) or an acrylic paint pen. Apply 2–3 coats of clear sealant over the code — this keeps it readable through rain, sun, and handling for months.
Writing #ROXCODE (e.g. #ROXABC123) on your rock makes it easy to find via Google search. We actively optimize for this hashtag, so anyone who searches for it will find your rock’s profile page quickly.
The full address ROXGEO.COM/CODE takes the finder directly to your rock’s card, where they can see its full travel history, previous finders, and photos from every stop on its journey.
