We know from multiple coelurosaurs preserved with feathers that the wing feathers attach to the second finger as seen in the first picture. |

I'm pretty biased toward therapsids, but an Anteosaurus would be greatly appreciated. If not, Hesperornis, Coryphodon, or Pristichampsus would also be really cool. Edited by Acinonyx Jubatus, Mar 20 2018, 01:45 PM.

I have been doing some searching on the web about Sivatherines and I've read that the head ornamentation on them was sexual dimorphic. So did female Sivatherines lack "antlers", ossicones or both? Where they present but just reduced in size? |

As I understand it, the males had more dramatic headgear, but the females were nothing to sneeze at. Take Prolibytherium. (Male on left, female on right.)

Prolibytherium is, if I recall correctly, more distantly related to Sivatherines that Sivatherines are to modern okapis and giraffes. Speaking of which, modern taxa doesn't help much. In okapis the females have no ossicones while in giraffes they do. |

I did not know that. Interesting. Well, for Sivatherium itself, I can find almost no reconstructions or photos of the skull, and of the ones that do exist, even fewer actually have intact ossicones. Artwork of the living animal shows a huge array of different ossicone shapes; some curve forward, some curve back, some splay outward, some are broad, some are narrow. It's very confusing. |

So, I've been working on reconstructions for Amargasaurus and Carnotaurus, starting from "fleshing out" the casts we have at the museum. Any tips regarding the amount of flesh and outlines ofthe tissues I got there ? ![]()

Well staring with the skulls, the antorbital fenestra and lateral temporal fenestra should not be visible in a living animal. The teeth would most likely be at least partially covered in lips.The point at which the skull connects to the neck should not be so visible either. Moving to the rest of the body, the bones of the shoulder would also not be as distinguishable. And lastly, the ischium would be a connecting point for the major muscles of the tail. It would not be jutting out in a living animal. Overall, these animals need to have more meat on their bones. |

Based on the species of plants found, the climate likely would have been subtropical to temperate. Many species discovered there have gliding capabilities so you would definitely expect a heavy forested area. |

Did Ornithischia have more flexible wrists than Saurischia? |

What prehistoric creatures do we have the most material of and/or are studied the most? I know Maiasaura peeblesorum is one of them due to the amount of fossils we have of them throughout their life span but are there any other organisms that come close |

Microraptor is probably the best known dinosaur by far, with Psittacosaurus in a clear second. Though if you're talking post Mesozoic things get a lot more confusing. |
