Problems and Hypotheses in Palaeontology

Dear Colleagues,

Like all sciences, palaeontology has its unanswered questions and unsolved problems. They include the phylogenetic and systematic position of enigmatic organisms, the palaeobiology of forms that have no obvious counterparts in the living world, the age of poorly dated specimens, the unusual preservation of certain fossils, the poorly understood causes of extinction events, the surprising geographical or stratigraphical distribution of certain fossil species, and so on. Finding answers to such questions sometimes requires a good deal of speculation, but palaeontologists should not be afraid of speculation, as long as it is based on solid facts and sound reasoning. We encourage the submission of papers, including speculative ones, dealing with outstanding problems and unanswered questions in all fields of palaeontology.
