The one-volume book of fiction by the Ural author I. Javadov includes two stories and a novel. These works, written in different years, are united by the author’s inherent sense of humor and friendly attitude towards his heroes, whom he sends either to another galaxy to thinking arthropods, or to intelligent dinosaurs in the Jurassic period, real cowboys of the Mesozoic. The works are written in the genre of “hard” fiction. Although some of the author's ideas differ from generally accepted opinion, it cannot be said that they contradict modern science.
