The Bible Dictionary mentions that there are parts of the story of Daniel not included in our Bible, but that ARE included in the Apocrypha (source). But what exactly is the Apocrypha? When the Old Testament was organized, compiled, and translated into the then-common language of Greek, the translators included books such as Bel and the Dragon and Books of the Maccabees (source). However, over time these books were recognized as not being divinely inspired. During the 1885 printing of the King James Version of the Bible the Aprocrypha was removed. These writings are not considered to be scripture by The Church of Jesus Christ of Latter-day Saints but can be instructive (source).
