1. Spinosaurus Drawing Tutorial: Easy Step-by-Step Guide

Today, drawing123.com will guide you how to easily draw a Spinosaurus with simple steps.

Let’s get started!

Step 1: The Initial Curve

Begin your drawing by making a single, fluid curve. This curve should start with a small, hook-like shape on the left, which will form the dinosaur’s snout and the top of its head. From there, it arches up and then descends into a long, diagonal slope, establishing the line for the dinosaur’s neck, back, and the top of its tail.

Step 2: Define the Head and Jaw

Focusing on the leftmost end of your initial curve, add another, flatter curve directly beneath it. This new line starts at the snout and curves back, creating a strong lower jaw and chin. Stop this line well before it meets the descending part of the main curve, defining the shape of the entire head in profile. The rest of the initial curve remains untouched.

Step 3: Sketching the Neck and Chest

Now, you will form the throat and front body. From the end point of your last curve (the lower jaw), draw a distinct line that curves smoothly down and backward. This shape should outline the neck, throat, and the front of the creature’s chest. Notice how this new line begins to define the full body width.

Step 4: Adding the First Leg Pair

At the bottom-front of the chest, where the neck curve ends, add the first set of limbs. Draw two small, simplified arms hanging down. Each should be slightly curved, and you can finish them with a few simple toes, forming small feet. These are the front, smaller legs of your dinosaur.

Step 5: Completing the Underbelly

To form the dinosaur’s stomach and complete the body, draw a new line that starts from just behind the arms you just added. This line should be relatively horizontal but with a slight upward curve, extending back to meet the start of the final slope of the tail. This line encloses the main torso.

Step 6: Adding the Main Back Legs

Move to the rear of the body, just where the back curve and the underbelly line meet. Draw two larger, powerful hind legs. These legs should be substantial, supporting the dinosaur’s weight. Finish them with large, well-defined three-toed feet, matching the size of the legs and creating a grounded stance.

Step 7: Shaping the Tail

The final line of the body is the underside of the tail. From the top of the rear hind leg, add a long, straight line that extends out to meet the very end tip of the original back curve. This completes a large, thick, tapered tail, giving your dinosaur balance.

Step 8: Detailing the Body Structure

Draw a line along the entire body that traces the distinction between the dinosaur’s side and belly, starting at the lower jaw and running back below the back curve to the tip of the tail. In the torso area, add another, smaller line for extra structure. This detail adds realism and form to your creature.

Step 9: Adding the Spinosaurus Sail

The defining feature is the sail. On the dinosaur’s back, between the neck and the tail, draw a tall, semicircular sail-like crest. This structure should be divided into multiple panels by several straight, vertical lines, giving it a fin-like appearance. This feature completes the Spinosaurus silhouette.

Step 10: Adding the Facial Elements

Draw two small, simple nostril dots on the end of the snout. Place a simple circular eye (with an inner circle/pupil). Add a distinct smile, which is formed by a small, curved line.

Step 11: Coloring Your Dinosaur

For the final, finished look, color the entire body of the Spinosaurus a friendly green. For the large sail on its back, choose a rich, contrasting reddish-brown to make it stand out. Color the underside of its jaw, neck, and belly in a lighter, pale-yellow or cream tone. To make it friendly, add a small, dark-colored eye and a subtle smile to its snout, completing your cartoon Spinosaurus.

2. Step-by-Step Instructions to Draw a Spinosaurus

Step 1: Sketching the Base Head Shape

Start by focusing on the right side of your paper. Draw a simple, flattened oval shape, reminiscent of an alligator’s head. This will establish the placement and general form of the dinosaur’s snout.

Step 2: Adding the Body Outline

Extend from the back of the head shape to the left, drawing a long, undulating line that establishes the overall length and curve of the neck, back, and tail. Create a smaller curve extending down from the throat to begin the neck.

Step 3: Sketching the Core Body and Tail

In this step, connect the initial body lines from Step 2 to form the full contour of the dinosaur’s back and the tip of the tail. Sketch in the form of the first forearm and hand on the side.

Step 4: Defining the Forelimbs and Torso

Focus on the lower half of the dinosaur. Define the shape of the body’s torso. Draw the second, matching forearm and three-fingered clawed hand, making sure both forelimbs are now complete.

Step 5: Sketching the Powerful Hind Limbs

Sketch in the strong, large hind legs. These legs should feature muscled thighs and large, detailed three-toed feet with distinct, curved claws. The Spinosaurus is now standing.

Step 6: Refining and Cleaning the Outline

Now that the whole skeleton is complete, refine all of the sketched lines. Go over your main lines with a single, continuous strokes to create a clean, crisp overall contour of the dinosaur.

Step 7: Adding the Decorative Dorsal Pattern

Add a pattern to the dinosaur. Draw a series of jagged, pointed, vertical lines starting from the back of the neck and extending all the way down the back and tail.

Step 8: Constructing the Sail Fin

This step defines the dinosaur’s key feature. Between the neck and the tail, draw a series of long, upward-extending, pointed rods. Connect the tips of these rods with curved lines to create the shape of the large sail-fin.

Step 9: Adding the Final Facial Details

Go back to the head to complete the face. Detail the eye and draw a complete set of sharp, conical teeth inside the upper and lower jaws. The Spinosaurus sketch is now finished.

Step 10: Applying Color to the Finished Illustration

For the final step, apply vibrant, even colors to the entire drawing. The main body, including the head, legs, and tail, is solid sky blue. All of the pointed dorsal patterns and the ribbed fin rods are a rich, warm brown. The fleshy membrane of the large sail-fin is colored in a bright, sunny orange, and the sharp claws on the hands and feet are dark grey.

3. Create Your Own Spinosaurus Drawing with Easy Instructions

Step 1: Sketching the Crocodile-Like Head

Start on the left side of your paper. Draw the main shape for the head, creating a long snout, a lower jaw, and a prominent crest above the eye area, similar to a smiling crocodile.

Step 2: Adding the Neck and Torso Outline

Extend lines backward from the completed head. Draw a curved line to define the neck and the underside of the torso, making a wide, heavy shape that narrows down to a pointed tail tip at the far right.

Step 3: Sketching the Forelimbs

Focus on the lower half of the torso. Sketch in two simple, clawed forelimbs that hang down, making them short but with distinct, hand-like claws.

Step 4: Drawing the Powerful Hind Limbs

Add the strong bipedal legs. Draw larger, muscled thighs that transition into lower legs and large, three-toed feet with distinct claws, making the Spinosaurus bipedal and standing.

Step 5: Defining the Body Anatomy

Connect the lower lines between the legs to finish the complete shape of the torso. Add a line defining the chest and abdomen, and refine the head-to-neck joint.

Step 6: Constructing the Sail Fin Structure

Define the most distinct feature. On the dinosaur’s back, sketch a high, ridged structure, and then draw vertical lines from the back to the top ridge to form the rods of the sail-fin.

Step 7: Adding the Back Scutes

Place smaller, triangular scutes along the spine, one behind the other. These scutes should run along the neck and from behind the sail all the way down the tail.

Step 8: Detailing the Face and Teeth

Finalize the face. Go back to the head to add facial details like the nose, eye, and a complete row of sharp, triangular teeth inside the lower jaw and upper muzzle.

Step 9: Applying Color to the Illustration

For the final step, apply vibrant colors to the finished illustration. Color the main body (head, torso, legs, and tail) a solid light sky blue. Color the underside (chest, belly, and tail bottom) a contrasting light yellow-orange. Make the sail-fin and back scutes a bright, uniform golden-yellow, and color the eye and all teeth white.

4. Draw a Spinosaurus Easily with This Beginner-Friendly Lesson

Step 1: Sketching the head’s base

Start the drawing with a few basic lines. These lines will create the base shape of the dinosaur’s head. Imagine two elongated curves that outline the upper and lower jaws, connected at the back to suggest the general form of the head.

Step 2: Adding the mouth and teeth

Inside the basic head outline, add details to form the mouth. This involves drawing serrated lines to depict teeth along both the upper and lower jawlines. Add small curves inside the head to define the eye and the nostril, giving the face its first features.

Step 3: Drawing the neck, back, and tail

Extend the existing head outline backward. A long, graceful curve should form the top line of the neck and back, continuing all the way down to create the top edge of a long, tapering tail. Add a single line at the back edge of the jaw to connect the head to the body.

Step 4: Defining the chest and throat

To create the throat and the front part of the chest, draw a line starting from the lower edge of the jaw and extending down and across. This line will define the form of the dinosaur’s neck and chest, giving it more body and substance.

Step 5: Illustrating the arms

In the chest and torso area, add the dinosaur’s front limbs. Draw two slender arms with clawed hands and individual fingers, positioned beneath the body. These arms should be drawn clearly and detailed with small lines for fingers and claws.

Step 6: Completing the Underbelly

Step 7: Drawing the legs

Move to the back portion of the torso to add the hind limbs. Draw two much larger, powerful legs. These legs should feature defined muscular thighs, sturdy knees, and large feet with three distinct toes and prominent claws on each toe, firmly planted for a stable stance.

Step 8: Refining the tail and neck details

Now, refine the existing outlines and add more details. A simple line can be drawn along the underside of the tail to complete its shape. Add subtle lines on the neck and torso to suggest muscle tone and skin folds, making the dinosaur look more life-like.

Step 9: Creating the dorsal sail

This step adds the most unique feature of the Spinosaurus: its sail. On the dinosaur’s back, between the neck and the tail, draw a series of tall, vertical lines. Connect the tops of these lines with a large, wavy outline to create a majestic dorsal sail.

Step 10: Colorizing the finished drawing

Finally, bring the dinosaur to life with color. For this particular style, color the main body of the Spinosaurus with a vibrant teal or blue-green color. A lighter yellow-cream color should be applied to the throat and belly. The striking sail on its back should be colored a rich reddish-orange. This simple, flat-color style completes the drawing.
