| 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!

Are/would they of been possible? I'm asking this question because of this awesome feathered quadrupedal theropod I drew a few years ago when I just started getting interested in Spec Evo. Too bad it's gone now, I really wish that I hadn't lost it

Well, technically, there were. IF you consider sauropods theropods. They were both saurischians, so they had a similar hip structure. While I don't see why theropods would become quadropedal, it would certainly be possible in my unpaleontological opinion. But my specialty is future evolution. When it comes to prehistory, I'm little more than a novice. I still trying to grasp the fact that almost all dinos had features or feather-like extensions. |

Sure why not? The early unspecialized theropods could produce quadrapedal forms easily. Spinosaurs could have produced a semi-quadrupedal form as well. If a kind of giant ornithomimid got even longer arms they could use their arms for walking. Maniraptorans are a bit tricker because of their wrists. |

Sorry Link, I don't give credit. Come back when you're a little...MMMMMM...Richer. Bread is an animal and humans are %90 aluminum. | |

You can ask me anything about prehistory. So I can help. |

Sauropods are not, by any stretch of the imagination, theropods. Other points stand, though. |

Didn't early quadrupedal dinosaurs stem from theropod-like early dinosaurs? Not theropods exactly, but wasn't the hip structure quite similar? Edited by KayKay, Apr 23 2010, 09:18 AM.

I think that yes, it is possible. Under certain circumstances, they could have dropped to all fours. I like to thin that Therizinosaurs , if presented the opprotunity, would have done so, especially if they became larger, fatter, and stranger...imagine strange 'qurry' beaked chalicothere type beasts, or huge woolly 'ur-sauropods' ! |

that would have been awesome. chalicotheres rock my socks. totally gonna have to draw that concept and probably end up sticking it up here. Probably look weird with the spindly theriznosaur arms thou, but oh well. Edited by MitchBeard, Apr 23 2010, 11:35 AM.

I often see renditions of spinosaurs on their front limbs. It would only really be useful in larger theropods, but they need the sprinting ability two legs gives. |

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." | |

Now, that's something i want to see. Must work on quadrupedal therizinosaurs for my awesome project.

Well that explains it. How is it described? |
