Long-tailed Paper Dinosaur

Cut two matching dinosaur sides from a folded rectangle, keep the back joined, and gently spread the four legs for a shallow three-dimensional display.

Preparation + 8 numbered steps

Materials

8 × 6-inch rectangle · 8 × 6 inches

One 8 × 6-inch rectangle (20.32 × 15.24 cm) of ordinary paper, ruler, pencil and scissors. Prepare the rectangle first. Adult help with scissors for young makers. No glue, separate legs or printed decoration is needed.

Blue and gold identify the original left and right halves, not literal paper colors. Orange marks the fold or cutting route. The back bridge must stay uncut. Diagrams are not full-size cutting templates.

Every step, at a glance

Compare your paper with each diagram after completing the action. Blue and gold identify the original left and right halves, not literal paper colors. Orange marks the fold or cutting route. The back bridge must stay uncut. Diagrams are not full-size cutting templates.

    PREPARATION · Original measured dinosaur pattern

    Prepare the rectangle

    Place the 8-inch edges horizontally and the 6-inch edges vertically. Keep the rectangle flat.

    Layers: One continuous uncut sheet.

    Check: The sheet is 8 inches wide and 6 inches tall.

    STEP 1 · Original measured dinosaur pattern

    Fold the top half down

    Bring the top long edge to the bottom long edge. Press the horizontal middle crease. Keep this closed folded edge at the top.

    Layers: Fold the entire top half behind the bottom half.

    Check: You have an 8 × 3-inch doubled packet with its fold along the top.

    STEP 2 · Original measured dinosaur pattern

    Mark the back, tail and head

    On the doubled packet, measure x from the left edge and y DOWN from the top fold, all in inches. Mark the upper route: (0,0.6), (2.5,0), (5,0), (5.6,0.35), (6.6,0.25), (6.8,0.05), (7.7,0.05), (8,0.25), (8,0.65). Join successive points with straight lines. The segment from x=2.5 to x=5 lies on the top fold: mark it KEEP, not CUT.

    Layers: Draw on one outer face; the cuts will go through both layers.

    Check: The long tail is on the left, and the small blunt head is on the right. The 2.5-inch back bridge is protected.

    STEP 3 · Original measured dinosaur pattern

    Mark the belly and two legs

    Using the same origin, mark the lower route: (0,0.6), (2,0.95), (2.4,1.15), (2.4,2.7), (3.1,2.7), (3.3,1.55), (4.5,1.55), (4.7,2.7), (5.4,2.7), (5.4,1.15), (5.7,0.8), (6.6,0.65), (6.8,0.8), (7.6,0.85), (8,0.65). Join successive points. These two routes enclose the full dinosaur side.

    Layers: The two leg shapes are cut through both layers, making four legs after opening.

    Check: Both foot edges are 2.7 inches below the fold. The belly gap reaches only to y=1.55.

    STEP 4 · Original measured dinosaur pattern

    Cut the upper contour

    Hold both layers together. Cut from the left tail tip up to the back at (2.5,0), then stop. Separately cut from (5,0) around the neck and head to (8,0.65). Do NOT cut the folded back between (2.5,0) and (5,0).

    Layers: Cut both layers together. Leave the back bridge intact.

    Check: The neck and head edges match on both sides, and the back still joins them.

    STEP 5 · Original measured dinosaur pattern

    Cut the legs and belly

    Cut along the entire lower route through both layers. Work slowly around the feet and into the gap between the legs; rotate the packet instead of forcing the scissors. Stop at the marked belly line.

    Layers: Cut both layers, including the gap between each pair of legs.

    Check: Each side has two broad feet, a belly, a long tapering tail and a separate neck outline.

  7. END STATEOriginal left: blue · right: goldRemove the cut waste

    STEP 6 · Original measured dinosaur pattern

    Remove the cut waste

    Lift away all loose paper outside the dinosaur outline. Keep the folded back intact and set the scraps aside. The animation separates the waste before omitting it from later steps.

    Layers: Retain both matching dinosaur sides and their original-paper back bridge.

    Check: The folded silhouette is one connected piece, with no loose legs or glued parts.

  8. END STATEOriginal left: blue · right: goldSpread the two sides

    STEP 7 · Original measured dinosaur pattern

    Spread the two sides

    Hold the back gently and open its existing crease a little, separating the two pairs of legs. Aim for about 30 degrees between the sides; do not flatten the model out.

    Layers: Move the original upper half only; keep the other complete dinosaur side still.

    Check: Four legs are now separated in depth, joined only along the back. The head and tail remain attached to each body side.

  9. END STATEOriginal left: blue · right: goldLevel the four feet

    STEP 8 · Original measured dinosaur pattern

    Level the four feet

    Tilt the whole dinosaur so both sides lean outward equally. Place all four foot edges on a flat surface and release gently. If thin paper will not hold the pose, display it supported or lay it flat; standing stability is untested. Optional eyes may be drawn afterward.

    Layers: Move the whole connected dinosaur, without another crease or cut.

    Check: The back is above the belly; four equal-height feet, a low neck, blunt head and long tapered tail define the dinosaur without ink.

Sources & notes

Just Fold Paper, Original measured low-neck dinosaur pattern (2026).

Original measured pattern ↗

The measured outline, English instructions, diagrams and code were authored for Just Fold Paper with AI assistance. This is an original geometric cut-and-fold design, not a traditional origami attribution or a reproduction of another dinosaur tutorial. No external template, text or photographs were copied. No project-wide reuse license is granted.

Adaptation: An original 8 × 6-inch blank folds to an 8 × 3-inch packet. Two matching long-tailed quadruped profiles remain joined along a 2.5-inch back bridge. Each side includes a real cut head, low neck, tail and two legs. The sides open about 30 degrees; the final whole-model tilt places all four foot edges at the same height. This stylized dinosaur is not a species reconstruction, fold-only origami or a rabbit variation.

Accuracy notes

Real-paper follow-along and paper weight have not been tested. Diagrams illustrate the sequence, not paper thickness, contact, collisions or exact layer visibility. Original material coordinates are retained through the half-fold, measured contour cuts, explicit waste removal and back-hinge opening. All four leg panels are real retained paper. The single uncut back bridge connects both sides. Rigid zero-thickness teaching geometry; scissors, finite paper thickness and standing stability are not simulated. Real-paper cutting, folding and balance have not been tested.
