Four days weekend was so long. I have been to national history museum. This was a meaningful trip. There were so many dinosaurs’ fossils, ancient animals’ model and crystal specimen. A huge Tyrannosaurus rex skeleton and Triceratops skeleton were located at the entrance of museum. When we entered into the museum more and more fossils of dinosaurs were appeared such as ichthyosaur skeleton, Stegosaurus eggs and diplodocus cranium etc. There was a show which was introducing a hunt way of puma in the museum. After the trip of museum, we had visited the USC which is the famous university in the USA. It was a different felling contrasted with UCR.
