When they find a buried skeleton they assess certain characteristics that determine male or female. Collarbone is straight across in a male, slightly slanted on female. Curve of the spine, S shaped on female more straight on male. Pelvic bone wider and tilted on female. Femur bone more of an angle on female, straight down on male. Once you study these differences you can spot the Trannies right away. Never mind the skull, but a lot of trannies get the forehead and jawbone shaved down.
