While they almost certainly existed back then just as they do today, I'm unfamiliar with any formations that preserve such an ecosystem. |

what about the hateg formation? or is Dinosaur planet outdated by today's standards? |

Oh yeah, forgot about the Hateg formation. Yeah, it was more-or-less tropical IIRC. |

Apparently the Daintree Rainforest in Queensland's been going strong for at least 70 million years (the whole area has been geologically stable for 180 million years, so its climate is completely determined by Pacific ocean currents). So while floral composition differs a bit from Maastrichtian Cretaceous rainforests, the fact is that it really is a direct "descendant" from an end-cretaceous ecosystem. So that's one. Apparently there were areas along Pangea's tropical belt during the Triassic that were rainforested as well. I'll have to look more into this though. Hateg Island I think was tropical rainforest or dry forest. It'd definitely be some variation of at least subtropical (apparently it was similar to Hainan in size, geography and climate, so that'd be a good place to start). |

is this redwoods height accurate?![]() and when would redwoods have reached this height? also are there any cretaceous stegosaurs? |

as for the cret stegosaurs, there's weurhosaurus. |

The most relevant is Wuerhosaurus, but there are a few other obscure genera, including Amargastegos and Paranthodon, but they are mostly fragmentary at best. |

Would a creature adapted to living in the Mesozoic be affected in any way if it was popped into the present? |

While I can tell you that trees in general were significantly larger than they are now (I'm talking as recent as the 17-1800s), I'm not entirely sure if the 896ft tree's legitimate. I haven't found a paper on it, but it's apparently part of a petrified forest in Texas where trees were preserved vertically at up to 150ft, with the longest fallen tree reaching 896ft. This was announced in 1927, so they may have recalculated the sizes since. |

Had Mamenchisaurus a tail club? |

Mamenchisaurus hochuanensis did. The others don't seem to. That said, there's a lot of work going into redefining Mamenchisaurus species (there's currently seven, and only one has a tail club, one is sometimes referred to another genus, and another is 1.5 times larger than the rest making it one of the longest and tallest dinosaurs known). The good news is that all Mamenchisaurus species are known from good fossils. Which is useful. |

How would dinosaur lips work? I've noticed plenty of theropod drawings where the lower jaw's set of teeth as well as the upper jaw's are fully concealed, but I don't get how said theropods could avoid biting their lips. |

Well monitor lizards have sharp teeth sheathed by thick lips, and they seem to avoid biting their lips pretty well.

So this list is one of those lists that people create describing the size of some dinosaurs. This one seems more legit than the rest considering it's from this year but I'm still having my doubts what do you guys think? http://youtu.be/7IL-OTSAerU |
