Biomineralization of primary carbonate cements: a new biosignature in the fossil record from the Anisian of Southern Italy

open access: yesLethaia, EarlyView., 2021
Biomineralization is a generic term used to indicate biological‐mediated mineral formation. In carbonate mineralization, nucleation of crystals can be: (1) controlled directly by the organisms, like in the skeletal formation of most metazoans; (2) induced by microbial communities, by indirect precipitation mediated by their metabolic activities; or (3)

From Guaratuba to Babitonga: a geologicevolutionary contribution to the study of the spatial distribution of the shell mound builders on the northern coast of Santa Catarina.

open access: yesRevista do Museu de Arqueologia e Etnologia, 2001
The paper presents a geologic-evolutionary approach to the shell mound along the coastal plain of Joinville, whose results indicate a possible route for the displacement of the shell mound builders between the Paraná southern coast and the Santa Catarina

Lutz's spontaneous sedimentation technique and the paleoparasitological analysis of sambaqui (shell mound) sediments

open access: yesMemorias do Instituto Oswaldo Cruz, 2013
Parasite findings in sambaquis (shell mounds) are scarce. Although the 121 shell mound samples were previously analysed in our laboratory, we only recently obtained the first positive results.

The Tricky Task of Fisher-Gardener Research in Conservation Paleobiology

open access: yesFrontiers in Ecology and Evolution, 2022
The study of sambaquis (ancient shell mounds) in conservation paleobiology is a complicated subject, especially when comparing body sizes of current and past mollusk valves to observe possible changes. There is a lack of information regarding how ancient
