    Why are only partial parts of dinosaurs found. Like where is the rest of the fossils? Do some decompose and some fossilize?

    A lot of the time when an animal dies, it either decomposes and the bones get scattered by water, wind, etc, or scavengers/predators eat a large portion of the carcass, and only a few bits get to be preserved.

    Take Deinocheirus, for example; only the arms and a few other bits were found; later it was revealed that, apparently, that particular Deinocheirus had been eaten by a Tarbosaurus (as indicated by bite marks and stuff). I would imagine a large sauropod carcass would attract enormous numbers of scavengers from miles around, so its not surprising that they're remains are almost always fragmentary and scattered. The only chance a dead dinosaur had to become completely fossilized would be to be buried in sediment very soon after death.
