This would explain why there are no archaeological relics of pachyderm germ-warfare laboratories...

Elephants are time-travellers! Their labs are in the future!


Look at how they've been knocking off mammoths and Stegodons and Deinotheria, all with bigger tusks than they have!
I don't think elephants and mastodons competed directly in the same environmental niches. Homo Erectus emerged out of a very crowded niche (tool-using proto-humans) and oddly...nobody else got out alive.
