Sorry about the double post (at least I had the decency to space them by roughly a day), but I remember either Darren Naish or Scott Hartmann (could've been both) at one point speculating that Yutyrannus might actually be an allosauroid. Does anyone else think this might actually be worth considering, or has it been discredited by now? |

What Naish did point out that there are some superficial similarities to carcharodontosaurids in the skull regarding the extra pneumatic holes along the crest, which were similar to Concavenator. But it's place as an allosauroid has been discredited. It's teeth were enough to seal the tyrannosauroid deal alone. |

OK, I have a question: So I have this: ![]() I want to make it look interesting yet scientifically accurate. Before anyone tells me to put feathers on it, I already intend to do so. I don't know how much feathering, which is mostly why I'm asking this question. So... any ideas? |

I think that the tail base a bit to thin. Since Megaraptorids seem to be very cursorial I would expect that they had some very developed Caudofemoralis muscles. As for aestethics maybe you could add some extra decoration to the nech throat pouch? Edited by babehunter1324, Mar 11 2015, 12:31 PM.

I'd inquire in to how it fit into it's habitat. They had to have had a specific niche given the proportions and those hands. Fish eating rings a bell but big hands and long legs don't specifically have to mean that. If it did rely on fish though then I'd go for the aesthetic most fishing birds use. Bald up to the knees, light body with dark markings around the eyes. |

Well, in terms of muscle mass, I think I got it right. The only known megaraptor tailbone(s) were fused together, probably as a result of an injury. Fossilisation distorted the transverse processes quite badly as well. On one side, they're angled quite normally, if a bit level. On the other, exactly the opposite direction:![]() I basically used the upward angled one, though not quite as upward to make up for the distortion in both it, the other side, and the neural spine. That seemed to be the reasonable option given what I saw in proceratosaurid skeletals. Probably won't look as thin if I cover it in enough feathers. ![]() As for its niche, I don't think it's an obligate fish eater. This wasn't built like contemporary unenlagiines (Neuquenraptor and Unenlagia). It was superficially more like a MASSIVE "compsognathid". I reckon it was probably taking on things like young Macrogryphosaurus, Futalognkosaurus eggs and young sauropodlets. Patagonykus if it was quick enough, maybe. Maybe even Neuquenraptor and Unenlagia themselves. I suppose if it had the reflexes or if climate conditions favoured it, fish probably were an option. I reckon it was probably like the area's theropod version of a leopard or monitor lizard. Small to medium game, anything it could grab whether it be ornithopod, another, smaller theropod, fish, turtles, lizards etc. Edited by Incinerox, Mar 11 2015, 01:02 PM.

In that case I'm thinking just treat it's coat like that of other tyrannosauroids. Rely more on primitive fuzzy feathers instead of pennaceous. as for color I think something impressionistic/Krentz style that will break up it's outline. if it's like a leopard it's going to want to get as close as possible. |

Is it possible that some Xingezhuang Formation members could have been found in the Nemegt too ? I don't think it's the case for Zhuchengtyrannus because Nemegt already has Tarbosaurus as the apex predator, but maybe a hadrosaur or Sinoceratops (IMO more likely due to absence of a species with a similar role in the environment) ? That is, if the environment of the two formations was similar, which I don't know. |

Both formations are separated by quite a big distance and might not be exactly from the same geological time. So I think that while it's possible it would be necessary to find more evidence to proof that they were there (similar deal with Alamosaurus on Hell Creek as discussed in the Saurian topic). Here I'm hoping for a Saurolophus akwardly glancing at a Shantungosaurus while wondering "how the hell did that thing got so big?" |

speaking of feathering...I need help figuring out plausible/ good feather distribution on a therizinosaur's head, any ideas? if you are wondering on what species it is, its a hell creek specimen

We have material for Beipiaosaurus, which, as a more basal representative of the therizinosaur clade, is a good place to start as any:

thanks, .......though I just wanted to know feather distribution on it's head (what areas were unfeathered vs feathered ) (I still appreciate the answer though )in an unrelated question, what dinosaurs would be the most practical/best to have in a zoo realistically(if dinos could be revived) my guess is hysilophodonts and small therizinosaus (Beipiaosaurus and falcarius) |

There's also small-medium sized Dromeasaurids, small Coelurosaurs, and the dwarf dinosaurs of Hateg Island. Basically anything the size of or smaller than an elephant. |

I reckon something like Tenontosaurus woulda been the easiest to maintain. It's about the size of a *small* rhino so its probably not as easily stressed as smaller ornithopods and it was not quite big enough and nowhere near armed enough to escape and cause havoc. It was apparently *very* adaptable, evolving in a semi arid climate only to THRIVE once their original habitat was turned into a swamp. Being an ornithopod, I bet it wasn't choosy about food either. Like a cow sized reptilian cow. Camptosaurus was likely the same. |
