| 背面描述 | Two sauropod dinosaurs identified as Nemegtosaurus mongoliensis are depicted in profile at the center of the field, rendered in a naturalistic style with one animal's long neck raised upright and the other lowered, their tails intertwining. The Latin binomial NEMEGTOSAURUS MONGOLIENSIS arcs around the upper periphery in a beaded border. The denomination 100 ТӨГРӨГ is inscribed in two lines in the lower field beneath the dinosaur figures. |

Nemegtosaurus mongoliensis was named for the Nemegt Formation in the Gobi Desert, where Mongolian and Polish joint expeditions in the 1960s and 1970s recovered some of the most significant Late Cretaceous sauropod material ever found. Mongolia's late-1980s dinosaur series was among the earliest national coinage programs to treat paleontology as a serious numismatic subject rather than novelty — issued just as the country remained firmly within the Soviet sphere, with Mongolian science heavily intertwined with USSR-sponsored excavation programs.
