In Dinosaurs Valley are around 15 concrete models - replicas of dinos found on Gobi Desert in Mongolia during polish expeditions in sixties. This exhibition was opened in 1975. Innitialy models were pale grey, they were painted around 20 years later.
In Poland you can find dino fossils in Opole and Kielce region, but remains are from smaller and older species (maybe one of the oldest dinos in the world).
