I mean, could they have? "Mammoths" in this case could be whales, sharks, and other large aquatic creatures. Considering the relative lack of deep sea archaeology going on, there could be an abundance of evidence of this that we simply haven't noticed. Plus, there's even extant examples of dolphins hunting sharks (and even knowing to flip them over to render them helpless).
