Hm, arent both animals members of families known for their cursorial
adaptions? Isnt "seek a good hiding place/curl up into a "defensive ball"
and remain like that until the danger is over" a behaviour more common
amongst animals that are not very cursorial in their adaptions? I wouldnt
expect such behaviour to be part of the standard repertoire for cursorial
animals - I would rather expect them to "run like hell". "The animal was
sleeping and got caught by some sort of catastrophy" sounds a more likely
explanation to me then "The animal faced some sort of catastrophy, broke
it's usual pattern of behaviour and subsequently got killed (apparently
without making even an attempt to uncurl and run!)". Sorry, but the latter
sounds way more far fetched then the birdlike sleeping posture.
