Ernesto Bachmann Paleontological Museum, Paleontological museum in Villa El Chocón, Argentina.

The Ernesto Bachmann Paleontological Museum in Villa El Chocón displays dinosaur fossils and prehistoric remains from the Neuquén Province region. The exhibits feature skeletons, teeth, and bone fragments that scientists have uncovered over decades at sites throughout the surrounding area.

The museum opened on 19 July 1997 and was renamed after Ernesto Bachmann, a paleontology enthusiast, on 16 March 1999. Its creation was driven by Rubén Darío Carolini's July 1993 discovery of Giganotosaurus carolinii, 18 km southwest of Villa El Chocón.

The museum's name honours Ernesto Bachmann, a local paleontology enthusiast, since 1999. Its collection grew from Rubén Darío Carolini's July 1993 discovery of Giganotosaurus carolinii, 18 km southwest of Villa El Chocón. The Choconsaurus baileywillisi sauropod takes its genus name from the town, and the museum also holds archaeological material from nearby sites such as Moro 1.

The museum sits in Villa El Chocón, on the shore of the Limay River in Neuquén Province. Inside, a laboratory and research area holds the official repository (MMCh-P), where holotypes such as Giganotosaurus carolinii and Bajadasaurus pronuspinax are kept. Look for the Skorpiovenator bustingorryi displayed as it was found at the excavation site.

The museum's repository, catalogued MMCh-P, holds the holotypes of Giganotosaurus carolinii, Skorpiovenator bustingorryi, Bajadasaurus pronuspinax, Choconsaurus baileywillisi and Leinkupal laticauda. The Giganotosaurus holotype itself is on display in the exhibition rooms. The Skorpiovenator bustingorryi skeleton is mounted as it lay at the excavation site, not posed upright.
