| 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!

The Pistrocene The Pistrocene is en era that begins 50 Million years hence and ends in 250 million years. It is an era that contains such wild, exotic diversity that is often has a body plan unlike anything scene today. The Pistrocene is derived form the term Pistris, meaning Shark in Latin, as such the name of the era itself opens a clue to the world that I will be showing you. People often try to make sharks that dwell on the land, and I find that people try to make it in a time frame far too condensed to be an actual possibility. Although I will be attempting to stay within the realms of biological reason, I will perhaps somewhat stretch what is possible for aesthetic reasons, so I tell you to remember that this is mainly for fun rather that 100% legitimate biological possibility, although I will attempt to keep my designs feasibly possible. The extinction event that leads to my world is a severe one, a huge meteor shower hits the earth that is far more lethal than the one that hypothetically wiped out the dinosaurs, this one has perhaps three asteroids of the same size that hit the earth with such velocity that almost all macro-sized life on planet earth becomes extinct apart from a few small invertebrate clades, which due to the lack of oxygen in the earth's atmosphere for the next 50 million years, will never rise to the top. Our survivor, or beginning species, is a small cartilaginous fish, or shark, in the family Triakidae, perhaps a leopard shark. Our survivor was able to survive the extinction through adapting an extremely low metabolism and an even smaller size, yet although these specialisations would be advantageous to survive a period of scarce food and ecosystem collapse, they will be somewhat crippling for the time ahead. 10 Million years after the major extinction event, a small genus of shark has adapted for surviving in a rock-pool environment, with the cartilage in the Pelvic Fin and Pectoral fin having increased in size and becoming more rigid, allowing the shark to anchor itself in a bed of rocks and attack unsuspecting prey. This body plan will provide a path for the dominant life forms on earth for millions upon millions of years to come. The shark itself has begun to show adaptations of skin breathing that can provide enough oxygen for short ventures above sea, and the Caudal fin has decreased drastically in size to become thicker and more serpentile, filled with powerful muscles and tendons to support the shark and allow it to push itself forward on land. I will show animals that have adapted 20 million years after walking on land, 50 million years and 100 million years, I am still at school and as such I dont have abundant time so updates will probably be slow, sorry

 *Pictured above, one of the early land dwellers pictured 20 million years after taking to land, extremely abundant as little competition exists. The front legs do not have fingers, rather these are more like tentacles, small appendages filled with muscle and tendons. The create has evolved startling color, with little to no predators, color is a virtue one can afford. The create moves through a hopping-like locomotion, propelling itself forward with its tail and landing and supporting itself on its front legs. This animals diet is primarily small insects, eggs of other 'land-sharks' and crustaceans that have moved onto the land. Pictured here is 80 million years after the extinction event, the create has poorly developed lungs, and still breaths primarily through its skin, the gills have closed over and are now no longer used. All though this animal is primarily a skin breather and small in size, time and evolution will change that. Edited by Jackson, May 21 2016, 07:01 PM.

I like the idea and the drawings but I feel like you should go more in depth on the species information. |
