About the book: 2019 / The book is dedicated to the study of mysterious animals - those that once lived on Earth, and perhaps never on it non-existent. Specialists in this young field of natural science are called cryptozoologists. These are people who have dedicated their lives to searching “on unknown paths for traces of unseen animals,” which has long been abandoned by venerable scientists who are afraid of tarnishing their academic reputation with “dubious” research. However, this search, in addition to the fact that it is extremely exciting, is also extremely important for science, because in any case, whatever the result, it brings a lot of useful things to today’s generation of researchers.
