"Dinosaurs Along The Silk Road" -- Sinofossa 2009 8: Visit To Li Da-qing's Lab

When in Lanzhou, we stop in at Li Da-qing's lab, wherein he has stored all of his latest and greatest acquisitions from the field. Because many of these are unpublished as yet, I can't put photos in of many things; the ones shown here are things already published. Da-qing works for the deep breath Fossil Research and Development Center of the Third Geology and Mineral Resources Exploration Academy of Gansu Province; he and his teams have been absolutely critical to recovering some of the most interesting and unusual dinosaurs to come out of China in recent years. His partnership with Hailu has been incredibly productive, and I hope it continues for many, many more years!

  • Right outside Da-qing's lab, some of his crew are assembling the first-ever mount of the ginormous sauropod Daxiatitan, using casts made in the lab. Here the base of the neck is being assembled, suspended from the forklift. Da-qing and Hailu described Daxiatitan in 2008. This mount will be part of a forthcoming exhibit dedicated to dinosaurs from Gansu, more or less all of which Da-qing has been involved with.

  • Here are the real cervical vertebrae of Daxiatitan, half enclosed in their molds and mother molds. This is how replicas of fossils are made: the real fossil is coated in rubber (latex, silicone, etc.), creating a mold (a "negative" of the real thing); the rubber-coated fossil is supported with a hard shell (usually of fiberglass) called a mother mold. For big, complex bones like these vertebrae, the molds and mother molds are done in sections so that each section can be removed individually. Once the entire bone has been molded and mother molded, the bone is removed from the mold, and the mold/mother mold pieces are put back together. Where the bone was is now a space in the exact shape of the bone. That space is filled with a casting material (plaster, polyester or polyurethane resin, etc.) to create an exact replica (cast) of the bone. Through a variety of techniques, the cast can also be made hollow for very large, heavy bones, creating a relatively strong and sturdy but very lightweight replica that is easier to mount and manipulate. I'm guessing that's what Da-qing and his people did with these Daxiatitan cervicals.

  • A femur of Daxiatitan -- this is a particularly interesting specimen because the bone has clearly been faulted -- the upper (showing) surface of the hip end of the bone (left) has been sheared off from the rest of the bone and moved a few centimeters away from its natural position. I don't know that I've ever seen a dinosaur bone faulted quite this cleanly...!

  • Matt and Jessie examining a thoracic vertebra of the bizarre, herbivorous, "pot-bellied" therizinosauroid theropod Suzhousaurus, which Matt and I were fortunate enough to have helped Da-qing and Hailu describe a couple years ago. Da-qing and his team have recovered many new specimens of Suzhousaurus that will help us better understand this dinosaur, and make it one of the best-known therizinosaurs!

  • ...and some of Da-qing's crew here drinking baijiu (pronounced "BAY-jo"). I don't know what to say about baijiu...there are the facts, like it is a sorghum-based liquor native (as far as I know) to China, it has a very licorice-like aftertaste (well, the "good" stuff does), and many natives (mostly men, that I've seen) drink it the way some of us drink water. Then there's my own personal opinions: it's a terrible, vile, evil drink that is only good for two things: degreasing engines and killing brain cells. 'Course, that's probably heavily biased seeing as what it did to me this very evening...

  • The next morning after my baijiu-induced coma, I get a visit from (drumroll) Pleasant Goat! To understand why I got this visit, you have to know the backstory: while we were in the airport in Beijing, awaiting the flight to Lanzhou, Matt, Jessie and I popped into a little cafe for some smoothies (I had "Mighty Berry," Jessie had "Raspberry Rash," and I can't recall what Matt had). The cafe was separated from a little book- and snack shop by a glass wall in which many books and things were on exhibit. I spotted what turned out to be a boxed set of DVDs of a show called -- I'm not making this up -- "Pleasant Goat and Big Big Wolf." As we later learned, "Pleasant Goat and Big Big Wolf" is in China, what things like Spongebob Squarepants and Pokemon are in the U.S.: a bona fide smash hit, animated phenomenon. But before we knew that, we just thought the name was hilarious. Pleasant Goat become a de facto tour mascot.
