| 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.

Trying to get some outside insight on this. It's in desperate need of revision and I'm trying to get back into it. Any ideas, words of wisdom, etc.? Concepts are welcome. Post comments here: http://zippo4k.deviantart.com/gallery/#Terrasaurus Edited by ItHasTeeth, Oct 7 2009, 08:45 PM.

I'm delighted this has received as much attention as it has. ![]() The erectus dragons are a keeper and I'm not changing them. In fact I'm tempted to try and illustrate them communicating with human explorers. Flight: Interestingly, most dragons don't fly. I kind of like this too. There are numerous small eudraconians that do either fly or glide and most of the wyverns can as well (their arms are reduced or gone, increasing the area for wing muscles to attach to). but almost all other one's you've seen cannot get off the ground. Wings are used primarily by large animals for communication (male displays or threats to would be predators by making the animal look bigger then it really is) and for thermo-regulation (like the sails of dimetrodon, but collapsible.) Dragon bones are hollow. On a side note, I dunno how their respirator system is shaped. Yeah, and there's still not fire breathing. XD |

For hollow bones you need an airsac respiratory system akin to that of birds and our beloved flying drepanosaurid relatives the pterosaurs. As for fire breathing, it still doesn't make sense because an animal with talons and teeth and etc like a dragon doesn't need a super weapon. It would be used by smaller species at most, but larger ones likely would loose the need to have fire breathing |

http://dipbsf.uninsubria.it/paleo/drepanosaurus2.htm Apparently Drepanosaurids may have had this as well. Which is great because the dragons are suppose to be descendants of an avicephalin-like animal. |

Then again Avicephala is now cosidered polyphyletic, with drepanosaurs closer to archosaurs than to things like Coelurosauravus |

Cool, so this is actually turning out to be quite plausible...hopefully we will dig up a 'dragon'-like animal from the Mesozoic, maybe even being a drepanosaur itself ! |

Hmm... I have new suggestion, what about a 'four-winged' dragon, it retains its rib-derived wings, but has also evolved a wing membrane on its fore-limbs, this adaptation allows the animals to maintain flight longer, and more efficiently, as well as appearing larger compared to other animals. |

Sounds nifty. Fire breathing could well be a production of random genetic fluctuation, like how the cuttlefish shell turned inside-out. I think a Mesozoic dragon would be out competed, because it would have to start out small, where pterosaurs and birds would win. And all large reptiles got kerthwunked at KT, so a Cenozoic one is pretty much out of the question. How about an interstellar Dragon Empire? |

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." | |

Dragons first started their evolution during the Permian, much like mammals and dinosaurs. As far as Avicephalia being polyphyletic, I again, did not realize this (though it makes more sense now). ---- No dragon empires. XD The mesozoic dragon-ancestors were probably small, Lagosuchus-like animals... the mesozoic would be when the dragons, drakes (the herbivorous quadrupeds), and wurms diverged from the common ancestors.

What about the 96% extinction? Sorry, just scientific curiosity. I like the idea of a dragon empire, i've had it fopr a long time. |

This would imply that the extinction may have been slightly less dramatic as in our time line. Yes this might change out comes slightly, but probably not by any real significant level (I doubt that a change of 1-2% would change very much in the long term...) |
