| Speculative biology is simultaneously a science and form of art in which one speculates on the possibilities of life and evolution. What could the world look like if dinosaurs had never gone extinct? What could alien lifeforms look like? What kinds of plants and animals might exist in the far future? These questions and more are tackled by speculative biologists, and the Speculative Evolution welcomes all relevant ideas, inquiries, and world-building projects alike. With a member base comprising users from across the world, our community is the largest and longest-running place of gathering for speculative biologists on the web. While unregistered users are able to browse the forum on a basic level, registering an account provides additional forum access not visible to guests as well as the ability to join in discussions and contribute yourself!

Yes, I know there has been this sort of topic already, but I want to go further on the speculations. What if from the Eocene, South America/Antarctica/Australia was never seperated? For starters, the Antarctic Circumpolar Current will never get to flow through, leaving the supercontinent relatively warm. But what about on a global scale? The Eocene-Oligocene extinction event would never have occured, as the Equatorial current and the Antarctic current mixed would still be distributing heat around the globe, keeping global temperatures relatively high? What would live in this supercontinent? How would the rest of the world effected? What would be the fauna and flora like? |

The end result would not be very different from Darren Naish's forest world, although I'm not so certain about the complete absence of grasslands. The interior of the continents, such as the interior of Antartica and Australia, could perhaps be sufficiently dry to allow their existence. The fauna of this Gondwanna would pretty much be the expected result: inumerous varieties of metatherians, xernarthrans, terror birds, giant flightless waterfowl, ratites, various terrestrial crocodillians (such as sebecosuchians and mekosuchines, or maybe notosuchians would have survived all along), various sphenodonts and monotremates, meridiungulates and etc. South America and Australia were invaded several times across the Cenozoic; maybe, like in the Green Antartica project, primates, rodents, tortoises and some other taxa invade SA from Africa just like they did on our world, but fauna invading Australia from Asia or South America from North America would presumably be fewer, as Australia wouldn't be as close to Asia as in our world and the same with North and South America. Thus, no monitors, no rats, no mastodons, etc. Edited by Carlos, Feb 5 2011, 05:51 AM.

Like Darren Naish's forest world? With the giant woodland salamanders of various niches, python like caecilians, massive predatory eagles, lots of chevrotains,,,, etc |

The world would be warmer and wetter, though it would probably still cool down a bit due to the Azolla event. There would also be a lot of plants from ancient Antartic Flora on Gondwana.

I like this project and have made many simular ones myself but lack knowledge of prehistoric gondwanan fauna and flora. Is it possible that groups simular to the thylacine, marsupial lion and those Saber-toothed South American Animals(Which are simular to marsupials) could rise and out compete the terror birds, Possibly even converge on the groups within carnivora(more so then they were)? |
