Mammoths, also known by their genus name Mammuthus, the "Mammon's Horn,"  may appear to be a fuzzy elephant,  but puberty hit this one hard. Like  its modern cousins, mammoths were  quite large creatures, with the  tallest of them reaching four meters tall with a weight of eight tonnes.  Both genders possessed long, curving  tusks, unlike their modern  relatives. Legends and mystique surrounded the mammoth as far back  as the 1600s, for many claimed to  have seen the mammoth in all its  furry glory. Thanks to cold  climates, mammoths were incredibly  well-preserved, and some bodies even  bleed upon excavation.  Living during the Pliocene to the  early Holocene, the mammoth walked the Earth for almost five million years across North America, Europe, and Asia. Depending on the location, mammoths' diets differed from one another but were unified in their  love for plants. They must have had some mean gardens. American mammoths were grazers that fed on trees and shrubs; others ate herbs and grasses. Baby Siberian mammoths  ate the dung of the adults due to soft baby teeth that could not chew grass at the time. Climate change  and over-hunting are blamed for the  extinction of this hairy creature. However, science might yet prove that extinction does not have to be forever as de-extinction efforts are focusing on the mammoth.
