| 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!

what if the bolid that hited earth during credacerous will be 12000 meters the extinct spicies are -all hemichorodates -all flower plants(with few exceptions) -all dinosaurs (with exception of bambiraptor) -all pterosaurs -all tailless amphibians -all rays -all rays -all mamals (with exceptions of gondwanatheria,marsupials and eutheria) -all squamates(with few exceptions) -all birds (with exceptions of ichtiornis) -all arachnids(with exceptions of scorpions and spiders) -all crocodiles sow wath you think (we speculkate about life on earth 200 milions after this K-T) Edited by janlor, Apr 21 2010, 12:04 PM.

Hm. Outright fusion on that scale could take a while in a bird. After all, penguins were a similar group of birds who followed such a path, and no fusion has occured in their kind. On another note, if Icthyornis is in a world where vertebrates are so few that echinoderms conquer the world, wouldn't it diversify into the dominant land form instead of merely retreating to the ocean? |

I'm reading those posts in a Jamaican accent and I'm in a decent mood instead of a rage mood. Did the starfish vascular system require the uptake of water at the actual area of movement or did it kind of do uptake over near the core? Seems like you could get away with a sort of diaphragm that let them shift pressure down an arm based on whether a section could balloon up or not if it is the latter. Heavy modifications of course but if you kill a nonsensical selection of animals to piss off forum members you might as well give them some kind of ridiculous luck. |

Bexi, not cool. This isn't to attack people. I think we shoudl just look at different aspects of this alien earth rather that just the plausibility of these tripeds. |

Um.. there is no reason an animal perfectly adapted to flying would leave the ground, especially when it's the only flying chordate left on Earth. The only other thing I can see it turning into are aquatic ground birds, but they never fused legs. And I've got a list of aquatic birds: Penguins Great Auks Hesperornithes Aquatic waterfowl like flightless ducks Flightless Cormorant And then here is a list of flightless birds. NONE ever fused legs. And then the problem of having their wings become legs. All flightless birds stayed bipeds. |

Maybe they are playing the floor is lava. For ten million years. |

Um... are you saying that for 10 million years the land is covered in lava? You are talking about COMPLETE extinction of life on land then. Not to mention how it is impossible (when the KT asteroid hit the land wasn't covered in lava, just fire). |

I'm pretty sure Zorku's response was a joke. Pandorasaurus you're getting yourself so tense, loosen up a little.

Tensile strength of a Pandorasurus suddenly jumped into my head. :slant: It wasn't even really covered in fire, it was just burny things that burnt and they soon got put out. It did rain embers for a while, and a lot of ash fell though. Mm. Plant nutrients. Wings are very weak and fragile. If you grab a bird's wing, it will rip and they won';t be able to fly. So how could they go over rocks and rubbish? |

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." | |

the wings changed into strong padles and than transformed into legs |

:slant: You mean flippers? If they evolve into flippers (which they probably won't you have the ENTIRE eutherian group that will do so before Icthyornis) they won't become legs. And even if they were to become land based after becoming aquatic (why would they?) the chance of growing fingers are very rare. After all, birds have lost all but 1 finger. And then there's the back legs. If the wings were to evolve into legs, then the back legs WON'T fuse. In fact, the chance (very rare, I estimate 1 in 50 trillion, at least) decreases with them going back on land, because quadrupedal motion is better than tripodal. If the legs were to fuse, they'd just die off. And if they were to become more aquatic and the legs fused like sea lions, they WON'T EVER go back on land. |

The microscopic one won't get any better than dewclaws. It's too tiny. And did you read my entire argument on why they can't exist? |

stop talking about tripods, now talk about legless gondwanatheria( i writed it good ?) its moving not side-by-side but up-and-down like most of mamals,also its chest and botoms are combined with head into one skull |

You never said to move out of the icthyornis. How does it move up-down? I know how it works for caterpillars, but it's slow and they have legs. And what do you mean that the chest and butt combined? If they do then it'll just be a head and tail. And what about the private parts? |
