The Museum of Paleontology Egidio Feruglio is a science research and exhibition center in Trelew city, Patagonia (Argentina). Its permanent and travelling exhibitions focus on the fossils remains from fauna and flora of Patagonia, as well as the geological changes that affected the region throughout prehistory. The museum is named for Egidio Feruglio.
MEF is also one of Argentina's main scientific institutions, with a robust research program in areas such as Vertebrate and Invertebrate Paleontology, Paleobotany, and Ichnology. It also has a group focusing on plants in semi-desert environments.
MEF's permanent exhibition is a journey into the natural past of Patagonia. It begins about 10,000 years ago, with the first human settlements in the area. In each room, specimens from both terrestrial and marine life forms are shown for each geological period, up to the early Paleozoic. The Mesozoic hall depicting the giant dinosaurs of Patagonia is perhaps the most popular attraction in the museum. The journey goes on at the mini-theatre with a film showing the evolution of the Universe back to the Big Bang itself.
