How to Draw an Acrocanthosaurus - Step-by-Step Tutorial

Step 1: First, draw the head, almost like a crocodile’s or alligator’s: long, flat jaws that open very wide, with a small crest where the eyes will be.

Step 2: Draw the eyes and face, with a large oval for the eye and large, sharp teeth in the mouth.

Step 3: Draw the body, with a long sloping line that will go from the back of the head all the way down nearly to the end of the tail. Then draw two lines to show the bottom of the acrocanthosaurus’ neck and underside. Finally, along the back, draw a row of lines that are the spines of the “sail” that the acrocanthosaurus is known for.

Step 4: Next, draw the front legs, which are short like other large therapods, but not as short as the famous tiny arms of the T-Rex.

Step 5: Draw the back legs. You may want to break it down into a series of curved lines, bending for the large thighs, knees, shins, and ankles. The feet were large and flat.

Step 6: Lastly, draw the tail, which will extend further back from where the tall spinal “sail” ends, come to a point, and extend back to the body, to the back of the legs.
