| 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!

I just realized this has some crurotarsians in it, like in TA. Whoops. Soz JF Aetosauria - Elephant/Pig like forms Phytosauria - Crocodiles Prolacertiformes - Small scavengers, except for Shavopteryx descendants, and isolated large creatures Rauisuchia - Big carnivores, and some gallimimid like forms Rhynchosauria - Hippo like creatures Trilophosauria - Ungulate like life forms Younginiformes - Lizards Avicephala - Bird like, chameleon like in some forms Thalattosauria - Sea-lizards Sphenosuchia - Most non volant arboreal carnivores I'll get some work started on this soon. If anyoone would like to help, just ask. Website link: http://different-world.weebly.com/index.html Edited by SIngemeister, Sep 10 2010, 07:45 AM.

No, unless you wish to call all ornithopods hypsilophodonts |

Thanks. By the way, some pictures are up on the website, and I welcome other artists contributions. |

Really, I thought they were at least still a family. Oh well. Nice work anyway. |

There are going to be birds in this, or quasi-birds at least. That is my current dilemma; whether to make them actual birds, albeit ones with four teeth, wing claws and tails longer than modern birds, or bird-likes? |

The albeit ones wouldn't fly so well I think, I'd think they would lose those extra features to lighten their weight for flying. They could retain if they find a use. When you say bird-like do you mean they evolved from something else? |

No, they evolved from dinosaurs, which did evolve in DW, but were mostly supppressed into the small light carnivore roles (think Velociraptor or Coelophysis). Thus they followed a source of evolution into feathers then flight, becoming one of the major competitors for air domination. By the end of the Cretaceous, they were winning over the declining pterosaurs, the smaller bats, and the less aerially agile Coelurosauravids. Then K-T Pterosaurs, most Ctenosauriscids, and Prestosuchids extinct. And most quasi-birds. Only a few survived, in pockets in Greece, Egypt and China. No-one is quite sure why they suffered so badly. Most of the more adapted forms died out, leaving the more 'primitive' genuses, who exhibited traits such as teeth, small wingclaws and relatively long tails. They never fully recovered from the extinction, as bats and avicephalids rushed to fill their places. Nowadays, they are fairly common around the world, yet have never acheived their former glory. Most of the roles are similar to ravens or frigate birds, with a few species that attack other flyers and others similar to songbirds. |

So do they keep those primitive features or do some lose them? |

By 'similar to songbirds', which characteristics do you mean? |
|
Time flows like a river. Which is to say, downhill. We can tell this because everything is going downhill rapidly. It would seem prudent to be somewhere else when we reach the sea. "It is the old wound my king. It has never healed." | |

Some would keep those primitive features, as most would use them for carrion eating or fighting off other animals, especially some Coelurosauravids who are known to attack aerial animals. By similar to songbirds, I mean small bird niches such as Chaffinches or Blue Tits |

Did any of these birds manage to produce flightless on an island? I'd imagine the ones with the primitive features would look something like non-avian theropods. Oh yes, your bats, did they evolve from the same or similar ancestor of HE bats or did they evolve from something different? |

I.) Probably, just haven't got round to thiking about it yet. 2.) No, DW bats are allotherians, the dominant mammal group in DW. |

Do your allotherian bats greatly differ from HE bats or are they much the same? |

Different skull shape, triconodont teeth, and some species show extreme sexual dimorphism in that males have rather long tails. And of course, their rather loud barks. I am probably straying in to the bizarroid realm |

A lot of triconodont where carnivorous aren't they, so would they be able to take up a lot arieal predator niches? I don't think it's that bizzare. |

I really like this project! Shame I don't know much about the Permian - I'd better go and study. The skarabs are a fun original idea - the facehuggers in particular are very clever. Why are trilobites extinct? I like trilobites. |
