Absolutely spectacular jaw show off by Geena Davis in the movie "Thelma & Louise". This is an A A Flat grade jaw. Angle is almost perfectly square. See the length of the vertical distance between ear lob and jaw angle... on non square jaw configuration, there is almost no distance. With Geena Davis there is like at least a solid 6 centimeters.

Chin is also projecting horizontally. She is a 6 foot woman, so the size of this jaw is certainly big relatively to other people.
