The National Collection of Mammals of the Institute of Biology, UNAM, will be 77 years old in 2024. This important event means a little more than three-quarters of a century of the CNMA supporting scientific research, teaching, and dissemination of knowledge of wild mammals in Mexico. Two years ago the CNMA opened its new facilities in a new building where it also supports the museum exhibition of mammals in the National Biodiversity Pavilion. Its collection of specimens as well as its associated curatorial data have become an obligatory source of reference for the study and conservation of Mexican mammals. For its safekeeping, the CNMA has guaranteed institutional support and will continue to be at the forefront in the construction of the national biological inventory of the mammal component of Mexican biodiversity. Therefore, another year of existence of the CNMA has been worthwhile.
