On dinosaurs, beliefs vary widely in the faith. Some Mormons believe humans and dinosaurs co-existed; some believe that dinosaurs never walked the Earth and that their bones were transported here; while others believed dinosaurs lived before humankind. Some Mormons do not believe there was death before the fall of Adam and Eve, dated around 7,000 years ago. The core of the problem is that the scriptures and the revelations simply don't talk about dinosaurs, and are inconclusive about whether there was physical death for other organisms before Adam and Eve's fall. This leaves each person to decide for themselves how the fossils we have discovered fit into the timeline of the plan of salvation.
