Marthanus was extinct and is a relative to a modern dylanus that has woolly fur and some blubber to survive in the cold environment. They are omnivorous, they feed on rodents, opossums, shrews, roots, tubers, reeds, seeds, and nuts. They live in forests, grasslands, and tundra parts of Asia, Europe, and North America. They first evolved around 1.2 million years ago as (mostly) hairless common dylanus-like dylanusid species, but around 400,000 years ago, when earth gotten colder, the marthanus evolved fur and some blubber to adapt to a colder environment. They originally went extinct in the year 1072 due to humans overhunting them for their blubber and fur as human's fuel for fire and protect human bodies.
The return of the marthanus
In June 7, 2011, however, extinction isn't forever. Some marthanuses were brought back through De-Extinction, using the domestic dylanus as a surrogate mother. These marthanus clones are now almost 100% marthanus. They were already reintroduced to North America, Asia, and Europe, where, due to conservation efforts, their numbers are now increasing, they multiplied from just 20 of each continents to more than 11 million on each continents. This is among the most successful extinct animal's revival, both the species themselves being brought back and their reintroduction back to the wild.
