American Mastodon (Aaron Lloveras)

This animal called American Mastodon was like mammoths but with some differences:

It had two big tusks that could get to five meters of lenght and were nearly horizontal. Young males had lower tusks that were lost in adulthood, but some studies have proved that females used them as mating challanges. The tusks were problably to brak branches and twings but sometimes they used them to fight.

This is known from fossils found ranging from present-day near Alaska, Florida and southern California.

This animal appeared about four milllion years ago, and disapeared from North America about 10000 years ago.
