Step 6: At the top of the head, draw a curved horizontal line as a guide for the parasaurolophus' cranial crest. The line should almost touch the body on the left.
Step 7: Under the body, on the right side, draw two angled lines as guides for the parasaurolophus' front legs. Bend the lines to indicate the joints. The line on the right should bend more, as the leg will be folded up.
Step 8: Starting inside the circle, near the left edge, draw a long angled line as a guide for the dinosaur's first hind leg. Parasaurolophus had longer hind limbs than forelimbs, so this line should be a lot longer than the lines on the right. Add the guide for the other hind leg on the left but make it shorter, as the top part will be hidden behind the body.
Step 9: Draw a couple of long curved lines on the left side of the body as a guide for the tail. The shape of the parasaurolophus' tail should be very wide on the right side, and it should come to a point on the left. The tail should be very long, almost as long as the body and neck combined.
That's it for the initial sketch! From this point on, press harder with your pencil to get a more defined sketch.
