How Do You Make Dinosaur Fossil Rubbings With Kids?

Place a flat, raised dinosaur fossil replica on a stable surface, cover it with thin paper, and tape the paper in place. Lay a crayon on its side and rub lightly across the paper until the outline and texture appear. Peel off the tape, lift the sheet, and label the print with the replica’s name. No digging, plaster casting, or real fossil is needed.

The key is choosing a piece the paper can lie against: a low-relief dinosaur bone replica or a dinosaur-themed rubbing plate, rather than a tall standing figure. Start with a light layer so there is room to adjust the pressure.

What You Need

• A large, sturdy dinosaur replica or rubbing plate with a flat back, raised detail, and no sharp edges.
• Thin plain paper, with spare sheets for test prints.
• A broad wax crayon with enough wrapper removed to expose its side.
• Low-tack tape, a flat table or tray, and a pencil for labels.

Use materials suitable for the child’s age and follow every product’s instructions. In the United States, art materials are subject to LHAMA requirements, including an ASTM D-4236 conformance statement. Look for that statement on the labeling, but do not treat it as permission to ignore warnings or put materials in mouths [1].

A kit is optional. Piano Potato’s fossils hands-on activity kit is described as containing fossil pieces and molds and is labeled for ages 6+. That does not establish that every included piece works for rubbing: check its shape and instructions first. Do not give that kit to younger children based on the activity suggestions below.

Choose a Suitable Dinosaur Shape

Check that the piece sits securely and that the paper can reach its raised details without stretching across large gaps. Prefer broad, rounded ridges over deep cavities or pointed teeth. If using a piece from a dig and explore kit, inspect it individually rather than assuming an excavated piece will print well.

For a dinosaur-specific activity, choose a labeled dinosaur bone replica or dinosaur design. A shell or ammonite can be a separate fossil-themed comparison, but label that print with its own name rather than calling it a dinosaur bone.

Keep small replica parts and loose fragments away from children under 3. U.S. rules ban toys and other covered articles intended for children under 3 when they present a small-parts choking, aspiration, or ingestion hazard. CPSC also explains the relevant exemptions; this is not a blanket ban on every small art supply [2]. Supervision does not override a product’s age label.

How to Make the Rubbing

Secure the Replica and Paper

Place the replica pattern-side up on a stable tray or table. If it rocks, choose a flatter piece. Lay the paper over it without wrinkles and tape opposite edges to the surrounding surface. Add tape at the remaining edges if the sheet shifts. Use low-tack tape only on surfaces it will not damage, and do not tape a fragile specimen.

Use the Side of the Crayon

Hold the crayon almost flat so its side, not its point, touches the sheet. Make light strokes across the covered design, working in a consistent direction at first. An adult can steady the base while the child moves the crayon; keep fingers clear of the rubbing area.

Check the Detail Before Adding Color

Pause after a light pass. If the outline is visible but pale, try another light layer. If the sheet is slipping or catching on a point, stop and fix the setup rather than pressing harder. Leave some paper visible between the colored marks so the texture remains readable.

Lift and Label the Print

Peel the tape back carefully, then lift the sheet without dragging it across the crayon marks. Write the name supplied with the piece and add “replica rubbing.” If the dinosaur or bone is not identified, use “dinosaur-themed rubbing” rather than guessing a species.

A Simple Test Before the Group Starts

Try this setup check with your own materials: make a light rubbing on a spare sheet, then make another on the same type of paper using the same replica, crayon, and stroke direction, changing only the pressure. Compare whether the ridges remain separate, whether the paper moves, and whether any edge catches. The aim is to find a workable setup for these materials, not to measure a child’s ability.

If the second print is darker but loses detail, return to lighter strokes. If neither print shows the pattern, try thinner paper or a different low-relief piece before handing out the materials. Keep the clearer trial sheet beside the activity as an example of the marks children are trying to make.

Adjust the Help to the Child

Package age labels come first. The following are activity adjustments, not tested developmental age thresholds: an adult can secure the paper and model a stroke for a child who needs help, while a more independent child can compare paper choices and label the results.

For a first attempt, offer one large piece and one crayon. Add other textures only when the child can keep the sheet still. Children ready for a comparison can use the same piece on different papers and describe which details are easiest to see. A darker print does not, by itself, indicate a different fossil or a more accurate result.

Why Is the Print Faint, Blurred, or Torn?

What Does the Rubbing Tell Kids About Fossils?

A rubbing records surface shape; it does not determine the object’s age or prove that a toy is a fossil. The National Park Service defines fossils as evidence of life preserved in a geologic context [3]. Keep that distinction clear when discussing real specimens and replica kits: a classroom replica models a shape, while the paper is a record of that model’s surface.

Finish by asking, “Which ridges showed up?” and “What changed when you changed the paper or pressure?” Store the labeled prints flat, collect loose crayon pieces, and return the replicas to their packaging. Follow the maker’s cleaning instructions instead of soaking or scrubbing them.
