Calcium needs? Smaller bones may well have been eaten incidentally.
Also -- tactically, it is logical that a giant biped that attacked a giant quad in an area where preservation was likely to occur (i.e., a swamp), would BE the fossil... albeit a flat one.
Attacked enough to cause weakening or hobbling? Don't have to hang on ;)
