Course: Dinosaur Ecosystems
Length: 6 weeks
School/platform: Hong Kong University/edX
Instructors: Dr. Michael Pittman, Prof. Xu Xing
Quote:Using the Late Cretaceous fossil site of Erlian, China as an example, we bring you to the Gobi desert, as well as leading international museums and institutions to find out how we reconstruct dinosaur ecosystems.
This biology and life science course will focus on the knowledge we can gain from studying animals and plants. You will learn about a dinosaur’s biology including their appearance, classification and diet. We will take a close look at the mostly meat eating theropod dinosaurs, as well as the main plant eating dinosaurs, the sauropodomorphs and ornithischians. At the end of the course, you will learn how palaeontologists use fossil and modern evidence to reconstruct dinosaurs and their ecosystems.
I love the folks at HKU. I’m still studying ancient Chinese philosophy, and China in general, because of their Humanity and Nature in Chinese Thought mooc; their Twitter account ranges from interesting to seriously amusing; and they really put a lot of work into their moocs. I mean, just the course logo required several revisions to make sure the dinosaur neck would “align with archaeological findings”. Staff did a great job covering the discussion forums, offering information and resources along the way.
Problem is… I just don’t care at all about dinosaurs.
I thought I’d give this course a try anyway. Given the teasers they were sending out, and my general affection for them, I thought maybe I’d change my mind. I didn’t, but that’s not their fault. The lectures were clear, beautifully illustrated (many of the drawings were by award-winning paleoartist Julius Csotonyi), and varied: some involved sifting through sands at the Gobi Desert, others hunting through back-room storage facilities of the American Museum of Natural History in New York, and they even took a trip to Glen Rose, Texas to check out fossilized dinosaur tracks.
The instructors were impressive. While the course was running, instructor Prof. Pittman made some news himself for his research into laser-stimulated fluorescence on fossils to reveal more detailed information than ever available about soft-tissue distribution – news Chelsea Clinton noticed, by the way. And Prof. Xu had previously discovered a new species, Gigantoraptor, among collected fossils from Erlian. They were joined by several other scientists during the course, some in the field, others in classrooms, museums, and labs.
The first four weeks reminded me of the catalogs found in Whitman’s poetry. I love Whitman, but by the time he lists every resident or occupation or flower the mood is lost. Much of the time, the lectures felt like a list of features of various critters, and I didn’t have the background to understand how anything related to anything else. So while it’s great to know that ornithominids and Alectrosaurus have arctometatarsalian feet that help them run faster, I’m not sure how those guys relate to therapods or ornithischians.
In other words, I really needed to create an overall taxonomy, but when I went looking for one, I found lots of conflicting information so I never got there. (addendum: during the last days of the course, I noticed a poster with a taxonomic layout was stored in a section of the course I hadn’t visited; I don’t know if it was there all along, but it’s exactly what I was looking for). I also should have made a chart for all the critters, with information about size, earliest and latest fossils, eating habits, etc. etc., but I didn’t do that either. I didn’t put enough effort into making the course meaningful to me, and that’s my fault. I feel like I let down the graphic designers who put so much work into a scientifically accurate logo.
The weekly graded quizzes relied on information-retrieval questions, so even with my cursory effort and primitive understanding I managed to do quite well grade-wise. I would think creative questions would be a natural for a course like this, more along the lines of “It’s 180 million years ago, the treetops are shredded, who am I?” But that might be a lot to ask for an introductory-level course offered to people from all educational backgrounds.
As I write this post, I’m beginning to see that I did pick up more than I’d realized from the course, and greatly enjoyed many aspects of it (which is one reason I write these posts). HKU has a great overview of the course that’s more reliable than my mumblings. Those who really like dinosaurs and have some idea of who’s what would probably find it packed with detailed information that helps determine what life was like for these guys; the forums were full of praise at the end of the course. Oddly, my favorite lecture was about foraminifera, teeny tiny marine animals unrelated to dinosaurs. Go figure. I also greatly enjoyed the sections on bone histology in the last week. I’d have to say the last two weeks were my favorite part of the course, in fact; they were less of a catalog of this-dinosaur-has-this-kind-of-teeth-and-that-dinosaur-has-a-beak.
Of course, the idea of dinosaur beaks is pretty cool in itself. Fun fact: Tyrannosaurus Rex had feathers. Or, at least, feather-like structures covering its skin. Want to amaze your friends? Tell them birds are dinosaurs. Which, by the way, they are, but only a scientist will believe you. A friend of mine (Hi, Lisa) just made a joke about the dinosaur-noodle soup she had the other night, and one of the clever tweets the course made, sent during Chinese New Year festivities, was a video about the Year of the Dinosaur (which most people are calling the Year of the Rooster).
About once a decade, I check to see if I still can’t play the guitar (I could when I was 16, but I seem to have lost it shortly thereafter), and more often I try to do some kind of visual art to see if I’ve suddenly developed some artistic sense (I haven’t). It was worth a try to see if I could get interested in dinosaurs, and if anyone could lure me in, it would’ve been these guys. I guess it’s just not to be. Foraminifera, maybe…
