Through taxidermy specimens, publications, some skeletons of animals and instruments occupied by the first naturalists in their academic studies, the exhibition seeks to bring the public closer to the background of natural sciences in our country.

It is organized on the occasion of the 150th anniversary of the Mexican Society of Natural History (NMHS) and whose first headquarters was, precisely, the INAH museum.

It is inhabited by around 380 pieces, among which stand out the skeleton of an orca, the skull of a mammoth and the prehistoric skeleton of the saber-toothed tiger (Smilodon).
