The iguana like spines on the backs of Diplodocus and related species...what do they look like fossilized and how come they aren't restored with the full skeletal mounts? Also when were they first discovered? And was this a trait restricted to Diplodocoids? Cause I've seen a few brachiosaurs restored with them as well Edited by BossMan, Jake, Jul 19 2016, 10:29 PM.

Maybe because they're not part of the skeleton? As for what they look like, here's a photo from Mark Witton's blog:

I'm curious about rhino's evolution. I am thinking what's the reason why most rhinoes nowaday have reduced so much hair. I know that in the phobocideans' case, it's due to their ancestor possibly be semi-aquatic but what about rhino? |

Iirc it's the same reason for rhinos. |

I agree with Flish cause some species like Teleoceros were very hippo like and were possibly semi aquatic |

Teleoceras is thought to have been a terrestrial grassland grazer, though. I think it has more to do with their "armour". Rhinos are famous for their leathery plates, which based on the distribution on extant species it seems to be the basal condition for the group. |

Well, those two are not mutually exclusive, are they? I'm sure most of us have seen the footage of Angel sharks swallowing Horn sharks almost as long as they are

I have not seen this. I was under the impression that Horn Sharks were much smaller than Angel Sharks. Either way, Eryops was probably a lot like modern frogs in the relative size of the prey it took- absolutely anything it could fit down its gullet, small things included. |

Would it be highpossibly for the Orcinus citoniensis to have similiar markings as the modern O. orca? Or was it probably more coloured as other dolphins, with a light belly and flanks and a darker back? |

Considering the fact we may already be dealing with several different species in the Orcinus genus even today that all have fairly similar markings, it's not an unfair bet that O. citoniensis would have them as well IMO. |

Why have I yet to see a lippy Xiphactinus? Is it because the teeth were too large to allow prominent lips? |

Well, the first widely publicized depiction that I know of (Nat Geo's Sea Monsters) was directly and obviously based off of the Goliath Tigerfish, which does not have lips covering its teeth. The other artists just copied Nat Geo. |

WWD's Sea Monster's special didn't cover its teeth either. That all being said, it's perfectly within reason to give, or leave out lips for Xiphactinus. Though it'd be interesting to see how it'd look with more barracuda-like facial coverings. |

So according to this friend of mine who claims to be a dinosaur expert there is A newly released paper that has "brand new evidence on megaraptora placement" putting them in the allosauroids group in which they just happened to evolve traits of tyrannosauroids. Has anybody heard of this paper or know where to find it cause he gave me a list of things to google but I haven't found the PDF |

Here you go. It was in the "ANOTHER Megaraptoran" topic. |
