Taphonomic arm postures of Plesioteuthis prisca (Rüppell 1829) compared to syn vivo arm postures of Sepioteuthis sepioidea reproduced from Mather et al. (2010). Note that this comparison does not implicate that the fossils show fossilized behaviour; it rather shows variation in contraction and extension or arms as well as how they could bend. Left: Outlines of fossils in black (white outline of gladius); right sketches from Mather et al. (2010) with the respective name of the posture.
