A series of designs I created as part of the Atlantis Bestiary 2 speculative evolution community project in the Paleostream discord, ran by Joschua Knuppe. Each animal has a scientifically sound ancestor created in Phase 1, which took place in the Paleocene, and given 50 million years to diversify and evolve until the Miocene for stage 2. Atlantis is a Madagascar sized island located on the mid Atlantic ridge that has been colonized by North American and European and African genera and left to evolve. The purpose of the competition is to explore evolution and biology in a speculative thought experiment to create lifelike forms that could have existed in this world were it real.
