From destruction to reconstruction: The paleopalynology collection of the Museu Nacional (National Museum) of Brazil after the fire

The fire that devastated the Museu Nacional of Brazil in Rio de Janeiro in 2018 led to the loss of significant portions of its scientific collections, including the paleopalynology slide archive. This article documents the evolution of the paleopalynological collection, from its historical development to the catastrophic impact of the fire, and the subsequent efforts for recovery and reconstruction. The reconstitution process involved the donation of materials from partner institutions, the preparation of new slides, and the creation of a digital infrastructure enabling remote access and long-term preservation. The integration of outreach activities and public engagement highlights the broader cultural and educational significance of the collection. By presenting the strategies and collaborative networks mobilized after the disaster, this study contributes to ongoing discussions about the preservation of scientific heritage in contexts of institutional vulnerability.
