Fallow Earth: distribution of prehistoric animals

As many know (And for the ones that don’t know) the world of Fallow Earth is the product of the harmful actions of human beings who left devastated much of the biodiversity, and a disaster of apocalyptic level that humanity not were able to stop, caused by an asteroid 7 km long that ended the half the existing species and almost totally to humanity on the planet. Luckily, humanity had begun to colonize the solar system and some of the humans survived outside the earth. The survivors gradually returned to the planet and eventually rebuilt the world lost and its ecosystems, implementing genetic engineering to bring extinction to several modern animals that perished. The highlight on some of the animals that make up part of the reconstruction is that they were also different types of prehistoric animals. The reasons why the humans revived them still are not clear.

The end of humanity on earth meant a signal to survivors that their time ended and nature must regain what once was destroyed, so that eventually humans left this new world after complete the task of reconstruction.

15 million years later... Humans established a rich and fairly prosperous interstellar civilization, thanks to genetic engineering have remained little changed but stronger. While in Earth, the planet has been transformed, life has found a way, and both the animals returned from extinction as the survivors of the event managed to adapt and take over the world.

In the current map, points the place of origin of every prehistoric species revived for humans, 

The following list are going to expose the species that have managed to migrate and colonize other places, between the in parentheses are the names of the continents/environments where they have migrated.
