Prehistoric fiction is a literary genre in which the story is set in the period of time prior to the existence of written record, known as prehistory. As a fictional genre, the realistic description of the subject varies, without necessarily a commitment to develop an objective anthropological account. Because of this, it is possible that the author of prehistoric fiction deals with their subject with much more freedom than the author of a historical fiction, and the genre also has connections with speculative fiction. In many narratives, humans and dinosaurs live together, despite the extinction of the dinosaurs and the evolution of humans being separated by millions of years. The paleontologist Björn Kurtén coined the term "paleofiction" to define his works.One of the derivatives of cyberpunk is stonepunk, a subgenre of science fiction. Stonepunk is a neologism born from the contraction between a stone and cyberpunk. This is an uchronia that refers to the massive use of technology in prehistoric times. Source: Wikipedia (en)
