In the start/mid 80's I read a novel in the school library about an archeologist who finds a buried skull with one wide front tooth instead of the usual two. He takes it to his lab where a "symbiont" organism crawls out and takes over his brain.
I read it in Danish, and I assume it was translated from English. I don't remember the name of the author.
The book had some very fancy neon 80's artwork on the cover, and it was one in a series of two or three. Its title was "Invasion fra rummet" in Danish, which means "Invasion from space", which of course yields no useful results on google.
I can add probably useless bonus info that the book's first chapter was filmatized for a youth book review tv program on Danish national tv in 1985-86 with Henning Moritzen as the archeologist.
