Just the one hand was found, in the old Space Marine book they had him fully, in the Index Astartes Article it said they found his remains and scrimshaw on his hand, in the previous codex it said the Imperial Fists take courage from his death and in the new book it says they only found one hand.

Also Curze saw Dorn covered in cuts surrounded by tons of murderous blades in a tunnel..during a vision, although it never confirmed he was dead from that, as opposed to Curze literally seeing Ferrus Manus's head without a body. Perhaps those murderous blades were necron flayed ones or something and that was the point where that necron lord captured him to put him on display?
