Does anyone the new revision of dinosaur taxonomy thing is about? I don't really understand much of it, but I think it only moves sauropods into a new group.

Basically we used to have two groups in Dinosauria, Ornithschia (most herbivores) and Saurischa (theropods and sauropods) but due to phylogenic comparison of early formso closer to the branch at the early Triassic we now know that Therapoda and Ornithschia are sister group. |

Or so they say. This was literally just released, so I think maybe we need to wait a little while to see if there will be more research on the topic? |

This is far from the rest time the sauropod/theropod relation has been questioned, the only difference is that this time they coined an entirely new clade to really bring the point home. |

Apart from the Ustad Mansur painting, what other coloured paintings of dodo's exist, that could be considered accurate depictions? https://upload.wikimedia.org/wikipedia/commons/3/36/DodoMansur.jpg |

Does anyone have a good-high-resolution image of Hadrosaur skin that covers a fairly large area of the body? And if not, does anyone have a texture that simulates it decently? Google's got nothing but lizard skin and things with watermarks. |

in WWD the stegosaurs was shown having pretty floppy back plates that almost seemed loosely attached to the body that would flail around with relative ease, was this true of stegosaurs or where they more "anchored" into the back? |

I'm actually working on one worth looking at, since my previous skeletal is wrong. The best one at the moment is probably this: http://jonagold2000.deviantart.com/art/Australovenator-skeletal-661929630 Edited by Incinerox, Apr 11 2017, 05:12 AM.

http://antediluviansalad.blogspot.ca/2017/04/sinking-ornithoscelidians-sitting-ducks.html This is definitely an interesting and thought-provoking article, and while I'm definitely going to take it with a grain of salt, the thing I want to know is this: what were the hydrodynamic capabilities of Ceratopsid frills? And would it have even mattered in the lifestyle he's describing here? |

Duane's back at it, I see. I have a gut feeling that most ceratopsians could not make it underwater. Too many bells and whistles, especially on their frills. For me it's pretty much a no. Any animal today that spends a considerable amount of time underwater has a smaller/more hydrodynamic head. |

Ceratopsians do seem to have a preference for floodplain like environments, though. |

This is the main sticking point with his theory, I think. He raises and supports good points otherwise- the thick skin, the floodplain environments and bone assemblages, etc. I don't know physics well enough to know how a ceratopsid frill would affect the hydrodynamics, but if it's not moving around very much anyway would the loss of streamlining be worth it? |
