I am rereading a novel from French author René Barjavel: “the ice people” on this exact theme. Scientists in the South Pole discover an ancient civilization 900k years old. Its also fun because he anticipates the near future quite accurately from 1968 when he wrote it. Well worth a read. https://en.m.wikipedia.org/wiki/The_Ice_People_(Barjavel_nov...
