They did that even in captivity, would be nice if there was a video of it, but we wiped them out before anyone captured this behaviour on camera. |

What are the main differences about Triceratops horridus and T, prorosus, other than time difference ? The article on wiki is quite messy about the species section. |

T. prorsus has a slightly longer nose horn and different beak shape, if I'm correct. |

I looked up at Deinonychus skeleton pictures on internet, trying to find a good one as reference picture. But then I notice that some skeleton are much different from each other. For example... Here is the one drawn by Greg. Paul... ![]() And this one from a museum I can't remember. ![]() As you can see, both have very different skull shape with the latter have much shorter skull. Which one is the more correct one, or do Deinonychuses have very wide varity of skull shape? |

Well, most skeletons I've seen look more like the below image (the one at my local museum, for example, has a skull like that). |

GSP's Deinonychus is correct. These short-thin-snouted skulls are reconstructions dating to the times when raptors were reconstructed in similar manner as allosauroids, hence the triangular skull that doesn't match a Velociraptorine or a Dromaeosaurid at all.

Can collagen fibers really look like feathers? According to BANDits like Fedducia they can, but obviously I have little reason to trust them. |

![]() There are some people who think that this fossil shows collagen fibers instead of feathers. Let's now celebrate how thick the animal would be overall if this was the case. Also see the quite noticeable gap between the bone and 'fibers', where actual flesh would be. |

Well, such long collagen fibers would make up a fin-like structure, like in dolphins, whose purpose in a dinosaur is a mistery to me. |

![]() Well, there's logic and there are speculations that advocate someting like this

A scaly semi-aquatic compsognathid would certainly be interesting, but not particularly likely.

@Bigwhale (post #295) : From the Huincul we also have the rebbachisaurid Cathartesaura, the carcharodontosaurid Mapusaurus, the abelisaurids Skorpiovenator and Ilokelesia, and also ornithopods... @Dr. Hax (post #296) : I'm quite sure that there are undescribed therizinosaurs in Hell Creek... |

Would Sauropods have feathers? Stupid I know but I'm curious what if they did and what purpose would it serve. |
