Why Saotherium Mingos is so small ? |

Because it was closely related to the pygmy hippopotamus, a lineage of hippos that seemingly are adapted for being a smaller river herbivore (although they wouldn't necessarily have to live deep in the jungle like today's pygmies) |

To what extant has protoceratops have appendages like quils. It's mostly depictured blad or with quills running down it's spine and tail. Is there more evidence? or is that up to speculation? |

Quills, bristles or keratinous spines are so far only speculative and artistic license on Protoceratops. |

What dinosaurs (and other extinct animals) are well suited to an environment similar to Arizona, im not really looking for a specific formation, just some good choises for a ZT2 zoo im working on. |

So, despite how we believe a Pterosaur such as Quetzalcoatlus was much more ground based than flying based... would Quetzalcoatlus still be capable of any kind of flight at all regardless? |

There'll be no foot-walking! Just air-flying!

Of course, there have been a multitude of studies proving Quetzalcoatlus could indeed fly. There's no reason to assume it couldn't. Witton and Habib did some studies on the mechanics of its flight. |

It's known that the Gobi dinosaurs like Velociraptors, Protoceratops and Oviraptors lived in desert environments quite similar to Southern Arizona. Some Triassic dinosaurs may have lived in arid zones too because of the size of Pangaea, as the interior of the continent was drier than the coast. Probably Coelophysids were hardier than other early dinosaurs and could live in Pangaea's arid center. Quetzalcoatlus and other Azhdarchid pterosaurs could indeed fly. The theory that they were pelagic fishers that bound their prey in flight was eventually discarded, and they are now seen as ground-based predators (like storks or caracaras). Greetings! |

Hmmm I don't know if this has been settled and probably has been questioned before. Are velociraptors indeed clever in overall or clever in terms that their brain is pretty big in comparison to their body? Or are they more like dinosaurian turkeys like some people say? |

Indeed, it really pisses me off when people assume because a flying animal is mostly terrestrial, that it must be a poor flier. Bar Headed Geese are pretty terrestrial, yet i doubt theres any other living animal that can fly for as long or as high as them (Vultures don't count, as they spend more time gliding on thermals than on full powered flight).

Dromaeosaurids (including Velociraptor) and troodontids were the smartest dinosaurs. It's thought some species had enough intelligence to hunt in packs, but the evidence of raptors hunting together (besides skeletons found together and footprints) is quite scarce and very open to speculation. Velociraptor for example is though to be a solitary hunter. Theropods showed an evolutionary tendency to increase their relative brain size, and Troodon, one of the last theropods, had the largest brain size in comparison to its body. Even though that might qualify it as the Albert Einstein of dinosaurs, Troodon wasn't smarter than most of modern birds and mammals (hardly smarter than a rodent and far from cats or dogs. Nothing like the JPIII raptors that literally spoke to each other. It's thought that dromaeosaurid brains, despite their size, weren't so evolutioned and these dinosaurs just had highly enhanced senses and did not have more intelligence than their modern descendants.

just watched NatGeo's Dino Death Match (as well as T.rex autopsy, T.Rex: Ultimate Survivor, you can see them on Youtube now BTW), and it's been a long time since i updated myself with the whole Nanotyrannus situation. So just to confirm it, is Nanotyrannus an official new species now? The evidences shown in the documentary is pretty convincing to me, but you know, you can never trust NatGeo too much... |

I think popular opinion is that its a juvenile T.rex, though I don't know if anything new on the debate has come up other than the Dueling dinosaurs that Might actually be a proper Nanotyrannus, though we might never know because of it being in a private collection.

that reminds me...when looking up the new calculations for T. rex's bite force it says now that confuses me whether that is: over all bite force or psi biteforce. |

According to Holtz, most paleontologists (including himself) on the show actually said that Nanotyrannus most certainly was a juvenile Tyrannosaurus and were extremely cautious when it came to the whole Nanotyrannus issue, but the directors cut those parts out. He posted something about it on his FB, but as he posts so much it's hard to find it
