RESUMO: Aquisição de coleções geológicas para o Museu de História Natural da Universidade de Coimbra, especialmente incidente no final do século XIX, remonta à reforma pombalina (1772). Após décadas de uso
intenso no ensino prático, muitos destes acervos encontram-se nos reservados do museu, incluindo uma extensa coleção de rochas do comptoir alemão Krantz, posterior a 1885. Esta inclui 470 amostras de mão
de rochas metamórficas europeias, das quais 34 com fósseis de plantas e invertebrados do paleozoico da Alemanha (19), República Checa (7), Dinamarca (4), entre outros países. Contém pteridófitas (61,8%),
graptólitos (23,5%), bivalves (5,9%), crinoides (2,9%), crustáceos (2,9%) e um “falso fóssil”. Este conjunto valoriza a coleção histórica de rochas, relacionando sedimentogénese, fossilização e metamorfismo, conteúdos temáticos dos programas de Ciências Naturais lecionados no ensino básico e secundário de Portugal. No seu todo, constitui um importante capital científico e didático, merecendo valorização e divulgação, particularmente, através da comunicação digital.
ABSTRACT: The acquisition of geological collections for the Natural History Museum of the University of Coimbra, particularly incident in the late 19th century, dates back to the pombaline reform (1772). After decades of intense use in practical teaching, many collections are now in the museum reserves, including a large set of metamorphic rocks bought from the German comptoir Krantz, after 1885. It includes 470 hand-samples of European metamorphic rocks, of which 34 with fossils of plants and invertebrates from the Palaeozoic of Germany (19), Czech Republic (7) and Denmark (4), among other countries. It contains pteridophytes (61.8%), graptolites (23.5%), bivalves (5.9%), crinoids (2.9%), crustaceans (2.9%) and a “Pseudofossils”. Its presence values the historical rock collection, relating sedimentogenesis, fossilization and metamorphism, themes of Natural Sciences taught in middle and high school. As a whole, the collection constitutes an important scientific and didactic capital that deserves to be preserved and disseminated, particularly, through digital communication.
