A Guide to Legs by ChrisMasna A Guide to Legs by ChrisMasna
A lot of people put "human legs" on dinosaurs. Not only when drawing, they are also very common in animatronics (90% of which are crap in the purest form). This needs to be corrected.
Also, be careful with max. movement range (not shown here). Examples: at maximum retraction of the hip, the femur will be at 90° (vertical). And even at maximum extension of the knee, femur and tibia/fibula will NOT be aligned at 180°. Never.

If you find any error, let me know. (Both in the anatomy and the grammar). Suggestions are welcome.

Oh I definitely needed to see this. I had this nagging feeling I was drawing legs terribly terribly wrong, and now I know why. Thanks!

Great, hope this will help many budding artists!

One minor thing - switch the labels for tibia/fibula.
