This does not have a simple answer.  A single sauropod pelvis (with
sacral vetebrae) can tell you almost everything about its general
appearance and size, since all sauropods follow a very similar body
plan, and the pelvis and vertebrae are generally diagnostic in
combination. On the other hand, a similar set of bones from a
hadrosaur tells you almost nothing, since hadrosaurs differ mostly
in the skull. Of course this means a skull is generally sufficient
to determine the appearance (and size) of a hadrosaur!

In short, it depends on the group and the particular bone(s) known.
