The Field Museum of Natural History, which offers more than 20 million artifacts, is a place where we learn a lot about the flora and fauna of our planet. The centerpiece of the museum, which attracts many visitors, is none other than "Sue", the largest and most complete tyrannosaur fossil ever known. Besides the skeleton of the T-Rex, the museum tells us more about our origins. The "Evolving Planet" section traces four billion years of life on Earth thanks to the skeletons of various creatures and primates. Ancient American civilizations can be discovered in the "Ancient Americas" section and the mummies of ancient Egypt can be found in the "Inside Ancient Egypt" section.
