Assuming that the dinosaurs that didn't have beaks had lips, would it be possible for them to snarl or is that a strictly more mammalian thing? Hopefully this isn't too weird or dumb of a question. |

Well that kind of depends on if their face muscles would allow that. If they had a face structure like mammals then that's possible but if they had a reptilian face structure most likely not. Reptiles can't snarl like mammals due to the muscle structure in their faces. Edit: Changed my post, I remembered something. Edited by Taurotragus, May 8 2015, 06:20 PM.

is it possible that Pachycephalosaurs have a sort of spongy shock absorber in between there skull and there brain to help them from getting brain damage while fighting. similar to how a woodpecker has a shock absorber in there beak to keep from getting brain damage while they drill on trees searching for insects |

I don't see why not (not that my knowledge on such things is particularly extensive). |

If the remains are anything i hope for Zanclodon as we need to re discover more dubious species IMO |

The primate lineage is thought to go back at least 65 million years ago |

Okay. I found this site. http://www.alltheworldsprimates.org/john_fleagle_public.aspx Is it accurate about primate evolution? Also is it possible for an early primate or an early relative of primates to live in say Greenland or a polar region during the Late Cretaceous? Edited by Guat, May 9 2015, 11:48 PM.

possabley and that sound unlikely since they evolved In Africa it has been estimated the origin of the primate branch to have been in the mid-Cretaceous period, around 85 mya Edited by Joe99, May 9 2015, 10:47 PM.

I'm pretty sure only hominids evolved in Africa, IIRC most of the earliest primate fossils are from North America and Europe (where ironically there are none left today save for humans), suggesting they evolved there first. Edited by CyborgIguana, May 9 2015, 11:40 PM.

even though the oldest known primates from the fossil record date to the Late Paleocene of Africa (Altiatlasius or the Paleocene-Eocene transition in the northern continents, circa 55 mya (Cantius, Donrussellia, Altanius, and Teilhardina) |

So if primates evolved during the Cretaceous-Early Paleogene would this be possible? |
