Today, drawing123.com will guide you how to easily draw a Brontosaurus with simple steps.
Let’s get started!
Step 1: Draw the Head Outline and Mouth
Start by sketching a simple rounded head shape on the upper left side. Include a curved line extending to form a cheerful, smiling mouth.
Step 2: Form the Long Neck
Extend two smooth, downward-curving parallel lines from the top and bottom of the head to form the long neck of the dinosaur.
Step 3: Outline the Back and Tail
Continue the back line of the neck over in a smooth, large arch to form the back, curving downward to form the top edge of the long, tapering tail.
Step 4: Draw the Front Legs
Add two thick, sturdy front legs directly under the neck and front body section, complete with rounded toes at the bottom of each foot.
Step 5: Add the Lower Belly Line
Connect the space between the front legs and extend a horizontal curve to outline the bottom line of the belly.
Step 6: Draw the Back Legs
Draw the two thick hind legs—one in the foreground overlapping part of the body, and one in the background—adding small rounded toenails on each.
Step 7: Add Underbelly and Tail Details
Draw a long, continuous curved line starting beneath the neck, following through the underbelly, and reaching along the underside of the tail to divide the main body from the underside.
Step 8: Add Facial Features
Complete the face by drawing a small circle with an arch for the eye, an eyebrow above it, and a tiny dot near the tip of the snout for the nostril.
Step 9: Color the Dinosaur
Fill in the main body, neck, head, legs, and tail with a vibrant green. Color the continuous underbelly strip running along the front of the neck, belly, and underside of the tail in light yellow. Color the toenails white, and fill in the pupil of the eye with black.
Step 1: Draw the Eyes and Smile
Start by drawing two side-by-side circular eyes on the upper right portion of your canvas, making the left eye slightly larger than the right. Add a small pupil inside each circle. Below the eyes, sketch a small, upward-curving line to form a smile.
Step 2: Outline the Head
Enclose the eyes and smile by drawing a smooth, rounded head profile that curves over the top of the eyes, extends down to form a rounded snout, and curves back under the smile.
Step 3: Draw the Long Neck
From the head, extend two long, gracefully curving downward lines—one from the back of the head and one from beneath the chin—to form the dinosaur’s characteristic long neck.
Step 4: Sketch the Back and Belly Outline
Draw a large, smooth arch extending backward from the base of the neck to form the top of the back. Below the neck, draw a short horizontal line to mark the bottom level of the belly.
Step 5: Draw the Foreground Legs
Add the front leg and back leg on the near side of the body. Draw them as thick, sturdy shapes that curve smoothly into rounded feet at the bottom.
Step 6: Add the Background Legs
Draw the two remaining legs positioned behind the body to show depth, giving them simple rounded feet resting flat on the ground.
Step 7: Draw the Upward Tail
From the rear section of the body, draw two long, upward-sweeping curved lines that taper into a point to form a tall, curved tail.
Step 8: Add Decorative Spots
Sketch various circular and semi-circular spot patterns across the dinosaur’s body, neck, tail, and legs.
Step 9: Color the Dinosaur
Fill in the main body, neck, legs, and tail with a light green color. Fill all the decorative spots with a dark olive green. The eyeballs are white with black pupils, and the entire drawing is outlined with clean black lines.
Step 1: Establish the Head Outline
Begin the drawing by forming the basic shape for the dinosaur’s head. This is achieved by creating an irregular, rounded silhouette, featuring a slight bulge at the top center. The overall form should resemble a wide, slightly flattened egg shape, placed near the upper-middle of the drawing area.
Step 2: Define the Long Neck
With the head outline complete, attach two long, mostly straight vertical lines to its base. These lines, which should flare slightly outwards as they descend, create the structure of the long neck.
Step 3: Sketch the Upper Torso and Shoulders
Extend the drawing by adding two curved lines that attach to the outer edges of the neck, just below the head connection. These lines should arch gracefully outwards and downwards, establishing the curve of the Brontosaurus’s shoulders and the very upper portion of its front torso.
Step 4: Map Out the Front Legs
Define the main bulk of the front legs by dropping two pairs of nearly vertical lines down from the curved shoulder shapes established in the previous step. These pairs of lines should be parallel, forming thick columnar legs. At the bottom of each pair, add a flat, horizontal base to represent the bottom of the foot.
Step 5: Outline the Hind Legs
Add the outlines for the hind legs, which are partially obscured. These are depicted by drawing two shorter, simple curved lines extending outwards from the sides of the front legs. Additionally, a smaller curved line should be placed low down between the feet, suggesting the belly area and the internal lines of the far hind legs.
Step 6: Connect the Torso and Define the Main Body
This step defines the main mass of the Brontosaurus. Draw two large, gentle curves starting from just above the leg lines on each side and arcing down towards the outside of the lower feet. These new lines form the outer contour of the massive body.
Step 7: Add Toe and Detail Lines
Bring texture and definition to the feet by drawing a series of small, connected ‘m’-shaped or scallop-shaped bumps along the bottom flat edges of all four feet, indicating toes and claws. Simultaneously, add small, horizontal, slightly curved crease lines at the joints and lower shins of all four legs to indicate skin folds and musculature.
Step 8: Create the Tail
With the main body and limbs established, it is time to add the tail. Draw two large, curved lines. These lines should originate from the left side of the main body, below the shoulder curve, and extend outwards to the left. The upper and lower curves should meet at a single, sharp point, forming a thick, curved tail silhouette that curves down towards the ground plane.
Step 9: Define the Face and Features
Complete the line work by adding facial features to the head. Inside the head outline, draw two large circles with smaller circles inside them for the eyes. Add two small horizontal dashes for the nostrils and a wide, friendly ‘U’-shaped smile.
Step 10: Coloring the Final Character
The final step is adding color to the complete drawing. Fill the entire body of the Brontosaurus, including the head, neck, torso, and tail, with a solid, vibrant orange color. The small, triangular toe claws on each foot should be colored a light grey. The eyes should be colored white with small black pupils, completing the character
Step 1: Draw the Head Profile
Start by drawing the profile of the Brontosaurus’s head using an angular, geometric line. Create this jagged shape, which features distinct straight segments for the top of the head, the snout, the jawline, and the throat.
Step 2: Begin the Neck and Shoulder
From the upper and lower points of the geometric head, draw two long, curving, or angled lines to define the neck. The lower line should have a significant bend before extending back to form the base of the neck and shoulder.
Step 3: Sketch the Front Legs
Define the front of the body by drawing two angular, columnar shapes directly beneath the base of the neck. These shapes, which represent the front legs and feet, use horizontal and angled segments.
Step 4: Outline the Upper Torso
Add the outline for the main body. Draw two angled lines to create a trapezoidal shape for the upper part of the torso. Connect the front end to the neck and front legs. Add another line extending horizontally to mark the bottom edge of the belly.
Step 5: Add the Hind Legs
With the upper body structure in place, draw two more columnar, geometric shapes attached to the rear of the trapezoidal body shape, forming the hind legs and feet.
Step 6: Create the Tail Structure
Draw the large, segmented tail. Attach the top of the tail to the back of the upper body and the bottom part to the back of the legs. This tail shape should be thick and angled, ending in a sharp, bent point.
Step 7: Draw Facial Details
Inside the existing head outline, add the facial features. For the eye, draw a small, geometric polygon like a rhombus. Create the nostril with a small dash and the mouth with another short, slightly angled line near the front tip of the snout.
Step 8: Add Inner Body Lines
This step involves creating the texture and internal divisions for the final coloring. Draw a series of straight lines: one running down the center of the neck, two small lines on the side of the neck, a long line across the lower belly and upper legs, and a final long line along the bottom edge of the tail.
Step 9: Apply Final Colors
The main bulk of the dinosaur, including the head, upper neck, trapezoidal torso, and upper tail, is filled with a solid, slightly periwinkle blue. The lower, smaller sections of the neck, the lower belly band, and the underside of the tail are colored a lighter, pastel blue. The small Rhombus-shaped eye is colored solid black.
Step 1: Draw the Back Line of the Neck
Draw a smooth, vertical curved line on the left side that arches slightly toward the top and curves gently at the bottom.
Step 2: Form the Head and Mouth
From the top of the initial curved line, continue drawing a rounded curve up and over to form the top of the head, creating a small snout bump, and curve it back inward to form a smiling mouth shape.
Step 3: Draw the Front Line of the Neck
Add a curved line starting from under the jaw line, extending downwards parallel to the back neck line to outline the front of the neck.
Step 4: Outline the Back and Upper Tail
From the middle of the neck, draw a large arch extending to the right to create the dinosaur’s back, continuing into an upward-curving line to form the upper side of the tail.
Step 5: Draw the Front Legs and Toes
Draw two thick, vertical legs pointing down from the body—one near the front chest area and one near the back—and add small rounded bumps at the bottom of each foot for the toes.
Step 6: Complete the Lower Tail
From the bottom of the upper tail line, draw a long curve looping down and forward to meet the back leg, closing the tail shape.
Step 7: Draw the Back Legs
Add the two remaining legs slightly behind the front ones to show depth, along with toe details on each foot.
Step 8: Add the Underbelly Line
Draw long, smooth accent lines along the inside curve of the neck, running down under the chest, belly, and under the tail.
Step 9: Add Facial Features
Draw two large circular eyes with pupil highlights, small curved eyebrows above them, two small nostrils near the snout, and a small curve at the corner of the mouth to finish the smile.
Step 10: Color the Dinosaur
Color the main body, head, legs, and tail with a vibrant green shade. Fill the underside strip running along the neck, chest, belly, and lower tail with a warm yellow-orange color. Color the pupils black with white highlights, and fill the toes/claws with a dark gray shade.
Hopefully, this drawing tutorial on Brontosaurus will help you easily create a nice drawing.
