When I was a university student I used to work for a paleontologist. A paleontologist is a scientist who studies dinosaur fossils. I would usually work in Utah and Wyoming state. My job was to look for fossils in very rural places. I loved traveling to these countryside places. There was usually no buildings or anything around for many kilometers.
This is a picture of when I worked in Utah state. This trip was especially interesting because we found ancient fossilized dinosaur footprints.
This is a picture of the dinosaurs footprints. The dinosaurs walked through mud millions of years ago and it turned into rock. (fossilized) 
Here is another picture. You can see many different kinds of dinosaurs walked through this place.
