the idea that they are muscle attachment points is not very valid, as there is no muscle that would realistically attach where the bumps are located on Concavenator, unless it was doing something weird with its arms, and that's pretty unlikely considering there isn't really anything else abnormal about them, and they aren't particularly large, either. |

One issue with that assessment. We only have quill knobs from a select few species of modern birds, they are far from the norm among feathered animals and typically they represent that something unusual is going on with those feathers on the surface. Typically quill knobs are found in birds that put their feathers under high stress, such as fast mid-air turning, or using their wings to fight. It's also important to note that in quill knobs the feathers don't anchor into the bone. Rather the quill knobs are anchors for specialized ligaments, which anchor a muscle, which anchors the feathers. *edit* Flish beat me to the punch, although his post makes my second paragraph more relevant.

Guess it makes sense that we have quill knobs from dromaeosaurids then, since there's evidence that they were regularly doing the things you say quill knobs evolved for. |

Yup, holding onto prey and balancing/beating it with flapping motions is exactly the kind of behavior they would be associated with. Moorhen are probably the best comparison for quill knobs in reference to non-avian dinosaurs, they are present because of the wings beating so during fights. |

People who think the discovery of a living non-avian dinosaur would disprove evolution. By that logic ANY of the numerous Lazarus taxa we already have should disprove evolution. |

To be fair, they'd have to be idiotic to even make that train of thought their first after such a discovery, regardless of whether one chooses to listen to reason. |

Because no layman knows Pachyrhinosaurus or Einiosaurus or literally any ceratopsian that isn't Triceratops or Styracosaurus. THAT is what bugs me |

Actually I'm pretty sure that IS a Pachyrhinosaurus, although not reconstructed in the best way.

Funny you say that, I'd say more people are likely to be able to name Pachyrhinosaurus because of the recent WWD film, I can't recall any recent dinosaur film that has a Styracosaurus and actually names it ... (latest would be Disney's Dinosaur, which doesn't name it at all) Regardless, the ones you named have all been in popular media already, not very obscure by ceratopsian standards (but hey, it's not a competition - often animals are well known because they are interesting) |

When people think fossils are some incredibly rare thing that can only be uncovered in the most remote areas of the planet. No, you can find them LITERALLY anywhere! In fact, you've probably seen them before without knowing what they were. |

Thats true! Why (True story by the way) our school rival Boone Grove (If that rings a bell) found remains of a Mastodon skeleton underneath what would become their baseball field back in the 90's The article may still be around to! Edited by BossMan, Jake, Apr 19 2016, 02:35 PM.

The fact that we lack Cretaceous bone beds from Sub-Saharan Africa. It's all fine and dandy that we have beds for Niger, Algeria, Morocco and Egypt, but they're all coastal swampy places. What was continental Africa like back then? |

It annoys me that Siamotyrannus is still reconstructed as a tyrannosaur. I mean it's been a metriacanthosaurid for...14 years? |

I heard somewhere that a giant Maastrichtian Abelisaurid was found in Kenya. Not sure how reliable that is, though, and I don't know any other details. |
