Strangeo Forum The Dinosaur Thread    Lollipop Lord C-Rex        10/24/2012 Welcome to the Dinosaur thread! I have created this thread so people can share facts and information, along with thoughts, about some of the most remarkable creatures to ever exist! Did you know that the largest ever dinosaur, Argentinosaurus (pictured above), was around 120 feet long and may have weighed over 100 tonnes?   Jagotka     10/24/2012 Love this thread already. Interestingly, most dinosaurs were actually vegetarian. Creatures tumblr Blog:Methods of Creatures Madness   ColonelJ   11/20/2012  1 I. LOVE. DINOSAURS. <3 I can't think of any interesting facts right off the top of my head, but there were several species of really tiny dinosaurs (such as compsognathus). And they were probably adorable. XD "Through the darkness of future past, The magician longs to see One chance out between two worlds: Fire, walk with me."   Missmysterics   12/4/2012 Fossils of dinosaurs have recently been found with pigment still present, so far this is only known to be possible with feathers, anchiornis; small bird-like dinosaurs, for example, were black and white with red crests.   Malkin Manager     12/4/2012 Thanks for this! I had to go and look it up, and it is AWESOME. My TCR Norns   Prodigal Sock Ghosthande     12/5/2012 They've found it for Sinosauropteryx now too, and for her it's actually somewhat visible to the naked eye; it turns out those light bands that appear on the tail of this famous fossil aren't just some kind of preservational quirk, they were her actual markings.   FlyingEttiNorn   12/12/2012  1 Did you know that there's a dinosaur called Irritator? Look it up!   Small Birb Pann     12/13/2012 They're awesome! I've always loved dinosaurs. I need to study them more since I'm lacking in the species knowledge department. Small bird who lives here sometimes, and wanders other times. Got Creatures related content to share? Submit to Heck Yeah, Creatures! Icon by gettehld on twitter!   Rha   8/4/2013 ^ This. If I had known better before, I'd be studying paleontology by now hahaha..ha..u_u   Solariana   8/25/2013 YESSS I'm so glad we have this thread! I'm studying to be a paleontologist, actually. One of the most interesting things I've read recently regarding this particular subject matter pertains to the hypothesis of bird-from-dinosaur descent. The article I read cites a number of important physiological differences between birds and dinosaurs to go against this widely-held belief, positing instead that the two groups of animals probably followed a partially-contemperaneous path of divergent evolution rather than a lineage of direct descent. In other words, the researcher who wrote this article holds it that birds and dinosaurs evolved alongside one another at some point in time, albeit from a single defining ancestral root, and that the two share so many features due to evolutionary convergence (the process of two different lineages developing similar traits via exposure to similar evolutionary stimuli and stressors). I personally think it's a lot more plausible than the hypothesis of direct descent. My personal reasoning for this is that because birds have an ornithiscian hip - shared primarily by various big, lumbering, quadruped dinosaurs such as ceratopsians and stegosaurs - it would have been difficult for them to have acquired this hip through direct descent. This is because if any dinosaurs were to survive the cretaceous impact, it would probbaly have been small, agile therapod dinosaurs able to run quickly and hide - and these kinds of dinosaurs have sauriscian hips, not ornithiscian ones. The huge ornithiscian dinosaurs would probably be too slow and too big to save themselves in the case of an asteroid impact. Thus, it would seem more likely that evolutionary convergence explains modern birds' existence, and their possession of ornithiscian hips. What do you guys think? Drawing today!   Sixty Third Karias   8/25/2013 I think I'm a huge and have always been a huge paleontologist fan, but, honestly and shyly saying the bird-dinosaur link subject isn't my favorite. This thread is old but man where was I when it was started. And to think, C-Rex's favorite dinosaur last I heard is the same as mine Lately my two big things I love studying though are new Ceratopsians and climate change in the early Cretaceous and how it affected species migration and evolution. -Karias; a bit fruity and gone bananas in the wrong climate!   Solariana   8/25/2013 Ooh what is that favorite dinosaur, karias? And that does sound like an interesing subject! Wht have you discovered? :3 Drawing today!   Rha   8/25/2013 I don't know enough about the subject, so I wouldn't want to form an opinion over what evolutionary theory for birds I think is more plausible, but I do LIKE the idea of something in between bird and dino, and that some dinosaurs had feathers (which has largely been proven, right?). The idea of something looking pretty and being so deadly at the same time is amazing...like (big) cats. Personally, I would like to do paleoart, but I'd need to learn so much more, and I don't have time for that now.   Manic Scribbler razander   7/13/2014  1 They're mostly not historically accurate (this was made in 1897!), but I think anyone with an interest in palaeontology should look at the artworks of Charles R. Knight. You know how the fossils of long-necked dinosaurs tend to have the necks bending backwards? They usually don't die like that, it just happens during decomposition.
