Microbial mats have been hypothesized to improve the persistence and the preservation of organic remains during fossilization processes. We test this hypothesis with long-term experiments (up to 5.5 years) using invertebrate and vertebrate corpses. Once placed on mats, the microbial community coats the corpses and forms a three-dimensional sarcophagus composed of microbial cells and exopolymeri...
Observations of Archean organic-walled microfossils suggest that their fossilization took place through both encapsulation and permineralization. In this study, we investigated microfossils from the ca. 3.0 Ga Farrel Quartzite (Pilbara, Western Australia) using transmitted light microscopy, scanning electron microscopy, Raman microspectrometry, and nanoscale secondary ion mass spectrometry (Nan...
Reconstructing the history of marriage and residence strategies in Indo-European-speaking societies.
This file provides additional information on the data and methods used in Fortunato (2011a, b), and discussion of the results of the fossilization of nodes Proto-Indo-Hittite (PIH) and Proto-Indo-European (PIE) for marriage and residence strategies.
