Museum of Paleontology Egidio Feruglio, Paleontology museum in Trelew, Argentina.

The Museum of Paleontology Egidio Feruglio is a natural history museum in Trelew, in the Chubut Province of Argentina, devoted entirely to fossils from Patagonia. It has several exhibition halls where original specimens and full skeletal reconstructions are arranged to show how life on Earth evolved over time.

The museum opened on 28 December 1990 in a former furniture shop on 9 de Julio street, with a staff of three. The Egidio Feruglio Foundation was created that year alongside CONICET and the Trelew municipality. In 1994 it hosted the VI International Congress on Paleontology and Biostratigraphy, drawing over 250 researchers from 19 countries. It moved to its present 3,000-square-metre building on 25 June 1999.

The museum is named after Egidio Feruglio, a geologist who worked in Patagonia in the early 20th century. Through glass windows, visitors can watch scientists in the fossil preparation laboratories as they clean and study bones recovered from the field.

The museum stands in Trelew, about 25 km from the Bryn Gwyn Geopark it administers near Gaiman; that open-air trail climbs the slope between the Chubut River valley and the Patagonian steppe. Inside, the permanent route runs as a timeline from the first human settlers of Patagonia back to the Big Bang, ending at the mini-theatre. The preparation laboratory can be viewed during the visit.

In 2014, researchers from this museum identified the Patagotitan mayorum, one of the largest dinosaurs ever found. A full skeletal replica of that animal is now on permanent display at the Natural History Museum in London.
