Mysteries of Planet Earth

Mysteries of Planet Earth: An Encyclopedia of the Inexplicable surveys reported mysteries across three broad areas: the natural world, the supernatural world and the vanished world. Karl P. N. Shuker gives particular attention to lesser-known cases, placing them alongside more familiar subjects such as the Loch Ness Monster and the Turin Shroud.

The book brings together accounts from cryptozoology, unexplained phenomena and lost or disputed histories, presenting each subject as a claim or reported case rather than settled fact. Its approach combines concise background information with attempts to assess evidence and consider plausible, rational explanations. The result is a wide-ranging reference work covering mysteries that have often remained outside mainstream popular treatments.
