One fine day last year, I finished up a module in Hong Kong University's Dinosaur Ecosystems course about Saurichians and Ornithischians and then went to the news. There, to my surprise and slight discontent, was an article announcing everything I just learned was wrong. The Clade Ornithoscelida had been erected which violently yanked theropods from Saurischia and placed them alongside ornithischians. This left poor old Sauropods alone with herrarosaurs. At first it made no sense, but then a picture formed in my head of evidence supporting it. The proto feathers of Psittacosaurus make more sense if they are grouped with Theropods, and both tend toward bipedalism. And with such a dramatic result, I assumed the reasoning was mighty well vetted. Fast Forward to few days ago as I take a dinosaur 101 course with University of Alberta. It begins the explanation for the placement of dinosaurs and their relations. Then it explains ornithischians and.... Wait a minute! You can’t put theropods next to sauropods like that, we just learned that was wrong! Wait, did we? Has the scientific community discredited this revision, is it arguing it, or is it simply sluggish to implement it? @Troodon maybe you could shed some light.
How are fossils Given ID names? All dinosaurs have a group, be it Ornithoscelida or Saurischia, Genus/Species names, and Common names. They all have Their own Collectors and field notes, too. But the most perplexing part is how they have individual ID's. How did FMNH PR 2081 get it's name? or MOR 555? i know the first initials, FMNH and MOR stand for the museum they are held in, but what about the numbers 2081 and 555? what about the PR in FMNH PR 2081? I am asking so when i research dinosaurs, say U. Ostrommaysorum, I can find the actual fossils instead of museum casts, full (yet fake) skeletons, and Find important field notes. if you know any other ways, please share. I am asking a wide audience, but I would prefer to direct it towards Paleontologists in The collection areas of museums, where the real fossils are stored. Thank you, and PLEASE HELP ME!!!!!!!
