Always thought this was Kotto's foot -- half of him in foreground, half of him in back when camera racks to his top half. That's why Ripley reacts with such horror.
Doesn't look like Lambert's foot to me.
It's Lambert's foot, as Veronica Cartwright has spoken of her time strung up in a harness to get those shots (the Parker/Lambert death scene was one of the last shot at Pinewood, on B stage during October 1978).
