Leonardo Pérez-Barría

Historical fossil localities are frequently lost because, among other factors, the outcrops have been actively mined or erased by urban development. It would be what happened with historical fossil localities from the old Valparaiso province, in which naturalists, such as C. Darwin, J. Dana, R. Philippi and J. Brüggen collected fossil specimens. Based on the historical evolution of underreported fossil wood localities and local historical collection records, we report on the fossil localities of Valparaíso, Placilla-Curauma and Algarrobo. Historically, most of the early collections were sent overseas and their final destination is mostly unknown. In addition, most historical collections deposited in local museums have lost their labels, limiting the information of the specimens. Nevertheless, morphology, lithology, and color mineralization allow to compare the old specimens with a few ones with labels, allowing to discuss what would be the origin of these collections, as well as assessing what happened with the demise of the localities from where these fossils were collected long ago.
