This museum collection is a project carried out by the Friends of Palaeontology and Mineralogy association, in collaboration with the Town Council of Onda. The association is in charge of overseeing the collection. It also carries out research tasks on paleo-habitats and disseminates information in schools, colleges and publications.

It is currently housed in the old mill of La Reixa, where we can also find the office of Tourist Info Onda.
