Extinct animals size

I like the look of Camarasaurus. I wonder if he moved his tail when he walked. 

I noticed where the fossils are found and it is the same places the other species are found. The North American badlands are rich with fossils. Many of these dinosaurs will have better specimens soon. People are still out there searching.   Maybe not at this exact moment. It is really cold out there right now. Come the spring they will be back out searching.
