There are many books and publications about Gideon Algernon Mantell, his own extensive publications and his associates, but the most authoritative is by Dennis Dean in 1999, reference below. In 1818 Mantell began to keep a Journal as he called it “a sketch of passing events”. The original copies of the Journal together with all the remaining archives of Mantell are kept in the Alexander Turnbull Library in Wellington, New Zealand, where one of his sons had emigrated. A recently published document makes available for the first time all those parts of Mantell’s Journal which could not easily be consulted. Was this late coming information due to Mantell's other strange discoveries. Discoveries that we would refer to as Out of Place Artifacts?
