Hi Xantor Im not talking skin texture as such - the jurassic park version of T rex simply took on board later thinking on skeletal articulation and posture the earlier 30's style for t rex may look fun but tends to bend the tail and spine to raise the head as much as they could away from the floor (Guess for the king of beasts they wanted it to stand really tall) it is very dubious as to whether the skeleton and musculature of a living t rex could contort this far - more to the point footprint evidence might even be pointing the other way now - if there is any posture evidence at all it is towards them having a stalking posture where they lower their height as much as practicable when hunting
