In Sundown89's own words: So, this is a speculative evolution project, while many aspects of this come from extant and extinct species, these animals do not exist (as far as we know). The general setting is Terra Nova, a hypothetical India sized piece of land that fragmented off of Gondwana (Africa, Australia, South America, India and Antarctica) in the Cenozoic Period. Terra Nova is in the tropical latitudes within the Pacific Ocean and has a mixture of rainforests, dry scrub, grassland, wetland, and montane habitats.
My two cents: If you like Sun's Oddity Ark about real animals, then you are going to love his fictitious animals. Give them a look, and have fun figuring out the landscape of Terra Nova. And as if that's not enough, there is also Tales of Discovery: Persephone which is set in Terra Nova. Enjoy. -FOP
