Obturator process
The obturator process is an anatomical feature on the pelvis of archosaurs.
It is a raised area of the ischium bone of the pelvis.[1] It is the origin of muscles that attach to the femur and aid in running. These muscles are called M. pubo-ischio-femoralis externus 1 and 2 in crocodylians. In birds the muscles are called the M. obturatorius lateralis and M. obturatorius medialis. They insert on the greater trochanter of the femur.[2] See proximodorsal process
