There is also the Zombie Effect (when a fossil is reworked and redeposited in younger sediment).

Like _Titanis_...?

The Zombie Effect explains why _Titanis_ always kept its forelimbs extended.

From Chandler (1994): "The almost vertical carpal trochlea of the
carpometacarpus of _Titanis_ shows that the manus was held extended... and could not be folded under the ulna as in other birds."

Outstretched arms are undoubtedly an adaptation to zombie-like behavior. Also a useful aid to scooping out brains.

Cheers
