A Million Of Years Ago
According to experts, the Columbian mammoth must have first appeared in the region a million years ago. The steppe mammoth, its ancestor, arrived from Asia a couple of millennia prior to this. For millennia, the huge beasts lived in the Valley of Mexico and fed on the vegetation in the area.
As Tall As A Giraffe
Experts say that the mammoths could grow as tall as thirteen feet, which is the same average height as a female giraffe. Even though there were similar European species, those grew hairy coats to keep them safe from the cold. This was not the case for those in North America. Business Insider noted that the Columbian mammoth probably had a lifespan of anywhere from 70 to 80 years.
