Capturing the sail, snout, and overall silhouette of one of the largest predatory dinosaurs in a clean side profile is what this guide focuses on, and the how to draw a spinosaurus tutorial fits right into the Dinosaurs and Extinct Animals collection on SketchOk. The open-mouthed pose adds a layer of detail that keeps the drawing from feeling flat.
What the 10-Step Walkthrough Covers
The tutorial runs through 10 steps and ends on clean black and white line art with no coloring stage, so all the attention goes toward getting the proportions and outlines right. The character is drawn in full side profile with the mouth open, which means the snout length and tooth placement get their own focused attention in the early steps. The neural spine sail is the most structurally demanding part of the sketch, since its curve has to read clearly against the body without looking separate from it.
Spinosaurus: Key Features to Keep in Mind
- Large distinctive sail along the back
- Long crocodile-like snout with sharp teeth
- Small forelimbs with sharp claws
- Powerful hind legs with large clawed feet
- Long tapering tail extending behind the body
If you want to practice more prehistoric subjects after this, the Troodon and brachiosaurus walkthroughs are worth a look since they each put a different dinosaur body type through a similar step-by-step breakdown. For a dinosaur with a back feature that compares interestingly to the sail, the stegosaurus guide works through the plates along the spine in the same structured way.
How the Step Colors Work in This Tutorial
Each step image uses a three-color system to show exactly what is new and what came before:
- Red Color: lines added in the current step.
- Black Color: lines completed earlier.
- Gray Color: base sketch for structure.

Finished Your Spinosaurus? Show It Off
Once the line art is done, drop your finished drawing in the comments below. It helps to see how different people handle the sail curve and the snout length, and the feedback loop is useful for everyone working through the same steps. All new tutorials go up on Facebook and Telegram as soon as they are published, a new YouTube video based on existing guides posts every single day, and Pinterest stays updated regularly if that is where you save references. If you enjoy working through extinct animals, the Irish elk and Parasaurolophus are solid next subjects with their own distinctive silhouettes to work through. Supporting the project on Patreon keeps new guides coming and also gets you access to unique hand-drawn coloring pages that are not available anywhere else.
Thank you for this. My son loves dinos and this is his second fav. The step by step helped me out so much. I can draw but this was my second challenge. Thank you again for making this possible.
Thank you for the feedback. I am happy that this guide helped. I’ll add more dinos soon. The new ones are much more accurate and in higher resolution.
