unknown Dinosaur bones

Mongolia is one of the country where many dinosaur bones are found, in the Gobi Dessert many bones are found, in the time of the dinosaurs they say that the Gobi dessert was a sea, and that's why there are many bones found. in the Museum of natural history in Ulaanbataar, the capital of Mongolia, you can find many of the bones how are found in Mongolia, also a big T-Rex skeleton, same like the one in American Museum of Natural History. also they found some dinosaur eggs. in the area called Bayanzag, in central/ south Mongolia is famous for there dino bones, there also some gers (Mongolian tents) with dinosaur bones in it, if you are lucky you can find little pieces if you search for it and know if you don't have just a rock or a real fossil.
the picture where made in also in the Gobi dessert, a old man how was driving around on his tractor was caring water to the local people in the area, he helped us because we where stuck in the soft sand with or car, and he told us about the Monastery and also about Dinosaur bones, and he wanted to show them.
the bones where just on a little hill, just in open air. the people don't tell it to everyone because they don't want that scientist take it away, and they want to hold it on his original place.
this was only just a spinal cord and a big leg bone, there where no peaces of a skull or something else.
