Carter Scholz and Glenn Harcourt’s 1984 Palimpsests is a stand-alone science fiction novel. It was the fourth novel in the Third Ace Specials series, which was edited by Terry Carr.
Professor Frederick Warner’s dig in the Neander Valley should have turned up a few ancient hominin bones (if they were lucky), bones filling in a few of the empty spaces in humanity’s pre-history. Indeed, particularly fine bones were discovered. However, sharp-eyed anthropologist Hans Camus spotted something else in the dirt, something that would up-end his career.
