En el pasado XXIV Encuentro de Jóvenes Investigadores en Paleontología celebrado en Bogarra (Albacete), Rodrigo Figueiredo y colaboradores presentaron sus últimos trabajos sobre las colecciones de cetáceos fósiles del Museu de História Natural e da Ciência da Universidade de Lisboa (MUHNAC). Concretamente, el inventario y la digitalización mediante fotogrametría, con el objetivo de crear modelos 3D que más tarde se incorporarán a un repositorio en línea, y contribuir así a la preservación de esta colección. Este trabajo se está llevando a cabo con la colaboración del Museu de História Natural e da Ciência da Universidade de Lisboa (MUHNAC), la Faculdade de Ciências da Universidade de Lisboa, el Instituto Dom Luiz (IDL), el Grupo de Biología Evolutiva de la Universidad Nacional de Educación a Distancia (UNED), el Museu Nacional da Universidade Federal do Rio de Janeiro (MN-UFRJ), el Instituto de Biociências de la Universidade de São Paulo (IB-USP), el Department of Ecoscience de la Aarhus University, el Centro de Estudos do Ambiente e do Mar de la Universidade de Aveiro (CESAM) y el Grupo de Etnologia e Arquelogia da Lourinhã del Museu da Lourinhã (GEAL). El resumen completo se puede leer a continuación:
Photogrammetry has become a tool widely used in Paleontology that provides different ways of supporting distinct lines of research (e.g. biomechanics, morphometry). This technique is a non-destructive and accessible tool for the digital preservation and accessibility of paleontological heritage, particularly useful for the study of large-sized fossils. 3D scanning minimizes physical handling, preserves the external morphology in high-resolution, and enables immediate and permanent global access to crucial anatomical information through digital repositories. The Portuguese Neogene is rich in cetacean fossils, mostly found in the Miocene of the Lower Tejo Basin. Museu Nacional de História Natural e da Ciência holds an important collection of cetacean fossils including specimens collected since the 19th century, and the first Portuguese fossil vertebrates ever published. This collection comprises at least 50 specimens, including the holotypes of Adicetus latus, Adicetus vandelli and Cephalotropis nectus; 71% of the specimens are attributed to Mysticeti, and 29% to Odontoceti. Most fossils were collected in Lisboa and Setúbal Peninsula, from sedimentary deposits spanning from Burdigalian to Tortonian. The digitisation and creation of a digital 3D inventory, ensures a backup of the collections against potential future catastrophes, particularly necessary after the fire that broke out in the museum in 1978. A total of 22 models has been already created, including the skulls of two odontocetes and three mysticetes. Depending on the size of the fossil, 180 to 250 photos were uploaded to Agisoft Metashape to create the 3D models (resolution of 400000 polygons, on average). The inventory of the cetacean collection has identified several unpublished specimens including cranial material from new fossil-sites such as Porto Brandão, Brielas, and Penedo Norte, some still needing fossil preparation. Ongoing digitization will culminate in an online repository of 3D models, providing a powerful tool for future research on both external and internal anatomy.
