How big are elephants (Indian & African) in comparison to mammoths and mastodons?

Question

What diffenet kinds of Mamoths and Mastodons were there?

Answer 1

I think it is best to narrow your question by discussing the African Bull elephant to the North American Mammoth.  Remember there is a striking difference in the size of the African and Asian elephants and as far as the mammoth goes, there have been found bones of Pygmy mammoths no bigger than a small cow.

Anyway, A North American mammoth could easily double the size of the African Bull...standing as much as 18 feet at the shoulder (though this would be a huge specimen.  Of course you know the tusks of some mammoths made it as wide as a charging bull dozer.
