haventbaptized Posted March 22, 2017 Share Posted March 22, 2017 This new analysis of dinosaurs and their near relatives, published today in the journal Nature, concludes that the ornithischians need to be grouped with the theropods, to the exclusion of the sauropodomorphs. It has long been known that birds (with their obviously ‘bird-like’ hips) evolved from theropod dinosaurs (with their lizard-like hips). However, the re-grouping of dinosaurs proposed in this study shows that both ornithischians AND theropods had the potential to evolve a bird-like hip arrangement- they just did so at different times in their history. http://www.nature.com/nature/journal/v543/n7646/full/nature21700.html http://www.nature.com/news/dinosaur-family-tree-poised-for-colossal-shake-up-1.21681 http://www.cam.ac.uk/research/news/new-study-shakes-the-roots-of-the-dinosaur-family-tree http://www.sciencemag.org/news/2017/03/t-rex-gets-new-home-shakeup-dino-family-tree Link to comment Share on other sites More sharing options...
BobWill Posted March 31, 2017 Share Posted March 31, 2017 I'm surprised to see this hasn't gotten more chatter on the forum. I guess the dino-nerds here are too busy taking it all in to comment. Assuming it all holds up to scrutiny this will mean we have to throw out all the old textbooks and learn this stuff all over again. It has some people acting like they thought something was wrong all along and they're glad to see it put right and others saying "not just no, buy heck no!" We've had the technology to run the numbers for a while and they are finding more of the older dinosaurs to run them on all the time. It sure looks like a lot of characters were considered so it all looks pretty firm but it's going to take a lot more work to sort out the new Ornithoscelida grouping. I'm making a big bowl of popcorn to snack on while the show goes on Link to comment Share on other sites More sharing options...
doushantuo Posted March 31, 2017 Share Posted March 31, 2017 I am not surprised,it's NOT a free access article This might take a while to become free access,it being very marketable stuff ,and believe me,they sure know it at Springer Of course NOT on the RG page of any of the gentlemen involved(believe me,I tried) Curious about the data matrix ,BTW. And methodology. Link to comment Share on other sites More sharing options...
