We don't know COLOURS. But the fossil showed clear vertical stripes on its crest. Like this:

Based on all the new specimens, is the general consensus that Utahraptor was indeed social? |

I don't think the fossils have been known for long enough to establish a "consensus" view quite yet, but it's probably a safe bet. |

If you look past one species and look at all the fossils across all dromaeosaurids, most notably ichnospecies, it's looking REALLY likely that at least the large game hunting species were social to some degree. |

Well, I have heard that there is a theory about Balaur is actually a herbivorous dromaeosaur if not another kind of manirapteran... Any opinion on this? |

It was since shot down. Andrea Cau proposed that the unusual proportions of its feet and its weird hands were a sign that it was trending towards a therizinosaur-like lifestyle. But further analysis of the known remains suggest that it was indeed predatory, especially since Fowler's paper on the whole "pinning down prey with their retractable claws and eating it alive" hunting method for dromaeosaurs. Even Cau himself has converted back to the mainstream hypothesis. But of course we lack the key pieces of evidence needed to settle this once and for all - teeth.

can we now say for sure if pachycephalosaurs did (not) head-butt? |

It seems very likely that they did, at least according to this article I found. The evidence seems pretty convincing to me. http://phenomena.nationalgeographic.com/2013/07/19/butting-heads-over-skull-injuries-and-dinosaur-head-butts/ Edited by SamtheMan, Feb 8 2015, 11:14 PM.

Nat Geo? not being picky or anything, but is that place even reliable?

The article seemed credible enough, I don't recall National Geographic being terribly unreliable but that could just be that I haven't seen more of the controversial stuff. As for the story, it was found on a few other sites but I used Nat Geo since that article had pictures of Pachycephalosaur domes with the injuries. If you really need to see those additional articles I'll post them here as well. http://www.huffingtonpost.com/2013/07/19/boneheaded-dinosaurs-pachycephalosaurs-head-butted_n_3620768.html http://scitechdaily.com/fossils-reveal-headbutts-may-have-been-used-as-a-dinosaur-courtship-behavior/ http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0068620 http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0036227 |

I heard here that smilodon may have climbed up trees and dropped on its prey because it was a poor runner due to its body shape and over muscular body do you agree http://youtu.be/No6mB6V1wL4?t=9m38s |

No. The front-heavy build was meant for strength, gripping onto and wrestling prey. Smilodon were going after big game like bison, camels, ground sloths, horses and mammoths. Hell, we even know them to PREFER camels and bison. These animals may be able to outpace humans despite their size, but over a short distance, probably not a Smilodon. They weren't going to be chasing down antelope or antelope like animals anyway. And because of their large...ness, they would not have frequently climbed trees. Lions today find tree climbing VERY awkward. Dangerous even. Many a lion has fallen to their deaths trying to steal a leopard's kill. Two things worth remembering here: 1) Leopards and jaguars are adept tree climbers, and will frequently take up arboreal habits on a whim, and neither are front heavy. Jags are stocky, yes. But not any more front heavy than other Panthera species. 2) Spotted Hyenas are front heavy as well, and they keep up with their prey. And that's for the *ahem* long run. So no. |

Sinosauropteryx was reddy-brown with white rings on its tail, like a Red Panda. Anchiornis was dark grey, with white and black spangled wings, red spots on its cheeks and a red headcrest. Microraptor was iridescent black all over, like a grackle. Inkayacu was grey and brown, though I can find no data on how these colours were distributed across its body. I do not know of any others. |
