Does the femur look rather shorter than usual? Also the ribs seem a little strange to me. Any thoughts?
Yes, the femur doeslook too short, or shorter than normal. But it could be because of the camera perspective.

but seriously... could be postmortem (because of the burial, weight of the soil, moisture, etc), or could have been due to ancestry (Sarmatian? Some other group off the steppe? The Romans eventually defeated the Sarmatians, sent the men into Auxiliary duty in far-flung parts of the Empire, including Britain, sold off the women and children), or diet.
