I wonder if the Earth's Children series by Jean Auel would fit what you're looking for. I haven't actually read any of them yet but I've heard really good things, especially about the first book, Clan of the Cave Bear. According to Wikipedia, the setting of the first novel takes places some 18,000 years before the current era and references the advance of the polar ice sheets. However, the descriptions I've heard of the series make it seem more speculative than fantasy.
