| 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.

I had a thought. Does anybody remember the pladcoderm fish from the Devonian, like Dunkleosteus? Well, what if they were able to get on land first? I imagined a T-Rex like biped with fins for this... What do you think? |

The jointed "legs" would help, but they probably wouldn't be able to counteract the rest of the body armor. Besides, they aren't actually limbs, being articulated with the armor only, so they wouldn't be any more useful than a coelocanth on land. |

Yes, that's true, but I imagine the early land pladcoderms using their fins like turtle flippers, to push around on land, and then evolve slowly a joint much like tortoises today. |

How would they push around on land if they didn't have joints in the first place? |

Um...who said anything about the pladcoderms flying? I thought I was fighting for the pladcoderms evolving into a T-rex style predator.And please explain the six-pillar legs for them, please?

well i figure at some point of time after conquering the land and solving all the stuff that you all are fighting about they would develope at least one group of flying vertebrate or at least i thought it was inevitable. and then there are the other 2 flying options which are.... 1: insects rule the sky forever. or 2: the flish evolve. |

i am here. what about the placoderms in the sea would they go extinct like in our world and then maybe millions of years later some of the land ones return too a sea that is a lot less compatible with them and force them too become a lot tougher and reevolve armor and become quite weird. |

That's what I'm saying!! ...well, kinda anyway. My idea is that a group of placoderms (likely the 'antiarchs') get on land, evolve into land based creatures, and can dominate the land. As for oceanic placoderms, yeah, they might go out, and then the land species could re-evolve into those niches. I mean, didn't the reptiles do that in the icthyosaurs, elasmosaurs, and mosasaurs? |

Maybe placoderms, if they moved on land, would become quite an odd rhino: slow-moving armored grazers. |

Well, yeah. I remember browsing around on Deviantart and finding some crocodile-hippo mix creature. Maybe some placoderms could evolve that way, too? I can see the bone-cruncher jaw as being fittable for a body design like that... Oh! Um, and what do you mean by crustacean-like? Do you mean like they get pincers and stuff? |
