Contemporary American novelist
Michael Crichton invokes this tradition in his novel
Congo (1980), which involves a quest for King Solomon's mines, fabled to be in a lost African city called Zinj. During the 1990s,
James Gurney published a series of juvenile novels about a lost island called
Dinotopia, in which humans live alongside living dinosaurs. In video games, it is most notably present in the ''
Tomb Raider,
Assassin's Creed,
and Uncharted'' franchises. The
Hanna-Barbera action cartoon
Space Ghost features a segment "Dino Boy in the Lost Valley", about a young boy named Todd who survives a plane crash and lands in a hidden prehistoric valley in South America. In another
Hanna-Barbera cartoon
Valley of the Dinosaurs science professor John Butler and his family - wife Kim, teenage daughter Katie, young son Greg, and dog Digger - are on a rafting trip along the Amazon River in an uncharted river canyon when they are suddenly swept through a cavern and caught in a whirlpool. Upon resurfacing, they find themselves in a mysterious realm where humans coexist with various prehistoric creatures, including dinosaurs. The Butlers meet and befriend a clan of Neanderthal cavepeople. In movies, the
Indiana Jones franchise makes use of similar concepts. Also comics make use of the idea, such as the
Savage Land in Marvel Comics and
Themyscira in DC Comics. ==Geographic settings==
