オピストコエリカウディアの化石を発見したモンゴル人研究者は誰
On the fifth day of fieldwork, Ryszard Gradziński, the geologist of the expedition, found a concretion of well-preserved bones which promised to belong to a fairly complete skeleton. Excavation started on the next day, revealing a nearly complete skeleton lacking only the head and neck. Until today, this specimen remains by far the most complete find of this dinosaur. The transport of the specimen out of rough terrain caused major technical problems. Stone blocks containing the fossils had to be moved some 580 m on improvised metal sledges made out of petrol drums before they could be loaded onto trucks. Because the skeleton was embedded in very hard sandstone layers, several blocks weighed over a ton. On the 9th of July, the packing of the skeleton into 35 crates started for transportation to Dalanzadgad; together, the crates weighed about 12 tons.
