Woolly Mammoth & Mastodon

 

The woolly mammoth is a species of mammoth related to modern day elephants. Earliest examples are possibly 150,000 years old and apart from a dwarf species which survived longer, its demise was at the end of the Pleistocene (10,000 years ago).


Because some mammoth specimens are so well preserved, Japanese scientists report that it may be possible to extract DNA from a carcass and eventually produce a baby mammoth.


Mastodons first appeared 40 million years ago and survived until 10,000 years ago. They are visually similar to mammoths, but not closely related. Mastodons were browsers, whereas mammoths were grazers - hence their different teeth. The name mastodon means “nipple-teeth”. See teeth here.
