From what I understand it's more of a traditional wetlands rather than the brackish mangrove swamp-like environment of the Kem Kem beds. |

Looking at many new brachiosauridae reconstructions they no longer have the famous long neck like say...![]() Instead they are done with a lot more mass on their necks like Paleop's deviation (Nothing against you I actually love it, i'm using it as an example is all) ![]() Is this a new speculation? and if so what is the purpose of restoring them in this fashion because I find it very interesting |

Because they kind of need room for muscle and tendons to actually move and support their necks. |

More up to date knowledge on dinosaur muscle anatomy, and common sense. It's all part of the whole thing against shrink wrapping. See, in slender necked sauropods, there's a serious lack in muscle which would otherwise support what would be (despite the air pockets in their bones) extremely heavy structures. Such muscles would actually connect to the base of the shoulders. Then of course, you need to add a gullet and windpipe (which the thin necked versions don't leave anywhere near enough room for). Then once you add skin and fat and stuff, it creates a very differently shaped neck. |

Interesting never thought the old way was a form a skin wrapping until now! I like it thanks a lot |

How flexible would a pachycephalosaurid tail be based on the evidence we have? |

How many known North American therizinosaurs have been found, and where have attributed/unsubscribed specimens been found in North America? |

I think Falcarius and Nothronynchus are the only described genera. The there are the footprints of Alaska, and I think I heared something about there being some undetermined Therizinosaur remains in the Cedar Formation, I might be getting it mixed with an Oviraptoran though... |

AFAIK the named genera are Falcarius and Nothronychus, with undescribed therizinosaur tracks also being known from the early Maastrichtian layers of the Prince Creek Formation IIRC. EDIT: Ninja'd!

Ceratosauria if that theory still holds up with finds from Deltadromeus |

Martharaptor is another species of North American therizinosaur from the Cedar Mountain formation. |

Nice find, I was quite positive there was Therizinosaur material in the Cedar Mountain Formation, but I didn't know it has been assigned to a genus already. |

IIRC the current evidence suggests it's most likely either an elaphrosaurid or a noasaurid. |
