How to Draw a Mosasaurus: A Fun Guide

Let’s learn how to draw a Mosasaurus, a cool dinosaur from the sea! Get your drawing tools ready, and let’s have some fun!

What You Need

  • A marker or any drawing tool
  • Paper

Step 1: Draw the Eye

Start by drawing a small oval for the Mosasaurus’s eye. Place it near the bottom left or right of your paper. Remember, even though the Mosasaurus is big, its eye is small!

Step 2: Sketch the Mouth

Draw a big slanted line going down for the mouth. Add a little curve at the bottom for the lower part of the mouth. Then, draw another slanted line going back up to the top.

Step 3: Add the Tongue

To make the tongue, draw a curvy line like an “S” from the back of the mouth. Make sure it curves down and then back up into the mouth.

Step 4: Make the Mouth Look 3D

Draw another slanted line from the top of the mouth down to the same point as the first line. Curve it to look like it’s going behind the tongue and connect it at the bottom.

Step 5: Draw the Teeth

The Mosasaurus has sharp teeth! Draw small lines for teeth along the top and bottom of the mouth. They should look small compared to the big dinosaur.

Step 6: Outline the Head

Sketch the top of the head. Start with a small curve for the nose, then draw a wavy line back to the eye. Add a curved line above the eye for the eyebrow muscle.

Step 7: Create the Jaw

Draw a slight slanted line at the front for the jaw, followed by a wavy line that curves back and up to form the chin.

Step 8: Draw the Neck and Tail

Start the neck with a curve going back, then curve it up and forward. For the tail, continue the curve back and up, using your paper space well.

Step 9: Add the Chest and Fins

Draw a line under the jaw that slopes down and back. For the first fin, draw a curve that looks like a whale fin. Do the same for the back fins, making them look like the front ones.

Step 10: Detail the Belly

Imagine the belly line going behind the fin and curve it upwards, getting closer to the line you drew before.

Step 11: Complete the Tail

Continue drawing the tail by matching the curve of the belly line. Make sure it ends in a point.

Step 12: Add More Fins

To make the Mosasaurus look lively, add two more fins. Start with a curve that goes down and back, connecting to the belly line.

Step 13: Draw the Spikes

Now for the fun part—adding spikes! Draw small upside-down V shapes along the back of the Mosasaurus. Make the spikes bigger as you move towards the tail.

Step 14: Final Touches

Great job! You’ve finished your Mosasaurus drawing. Now, let’s add some color!

Coloring Tips

  • Use dark gray for the body and layer different shades for depth.
  • Color the inside of the mouth red.
  • Optionally, use a white colored pencil for texture.

Conclusion

You did it! You’ve drawn a Mosasaurus! Feel free to add more to your drawing, like a background or other sea creatures. Enjoy your drawing adventure, and have fun!

  • What do you think it would be like to see a real Mosasaurus swimming in the ocean? How would it move, and what sounds might it make?
  • Have you ever drawn a dinosaur or another animal before? How did it feel to create your own version of it, and what did you enjoy most about the process?
  • If you could add anything to your Mosasaurus drawing, like a background or other sea creatures, what would you choose and why?
  1. Explore Real-Life Mosasaurus: Take a trip to your local library or use the internet with an adult to find pictures and videos of real Mosasaurus fossils. Look at how scientists think they might have looked when they were alive. Can you spot any differences between your drawing and the real Mosasaurus? Share what you find with your class or family!

  2. Create a Mosasaurus Habitat Diorama: Use a shoebox to create a 3D habitat for your Mosasaurus drawing. Gather materials like blue paper for water, green paper for seaweed, and small rocks for the ocean floor. Place your Mosasaurus drawing inside the diorama. Think about what other sea creatures might have lived with the Mosasaurus and add them to your scene.

  3. Imagine a Day in the Life of a Mosasaurus: Write a short story or draw a comic strip about a day in the life of your Mosasaurus. What adventures does it have in the ocean? Does it meet other sea creatures? Use your imagination and share your story with your friends or family!
