No, once you obtain it, you unlock it.
There are 13 skulls hidden in each of the levels of Halo 3. They are way out of the normal way to complete the level so the only way you can really obtain them is to actually know where they are. Just look up Halo 3 skulls on Google or Youtube and they will show you exactly how to get there. Some of the skulls are relatively easy to get but some such as the Famine Skull can be very difficult. Once you come upon a skull just click RB. You do not need to finish the level in order to get the skull. You must start from the BEGINNING of the level and play on normal, heroic, or legendary to get the skulls.
You have to be on normal or higher. However, the skull will not spawn if you start from a checkpoint, you must start from the beginning of that level.

The Top of sceptre is a piece of the Skull sceptre that is dropped by catablepons on the third level of the Stronghold of Security. It is combined with the bottom of sceptre to get the runed sceptre. It has about a 4% chance of dropping and is considered the hardest part of the Skull sceptre to obtain.
Yes they do ! They have a complete skeleton including skull, spine and rib-cage.
