Evidências de vida no ediacarano inferior da Bacia do Itajaí, SC
(Universidade do Vale do Rio dos Sinos, 2006-01-06)
In Brazil, the occurrences of macrofossils become scarcer as increase the age of the sediments and the intensity of the processes of diagenesis and/or metamorphism, being extremely rare the pre-ordovician fossil record. ...

Evidence for an Early-Middle Miocene age of the Navidad Formation (central Chile): Paleontological, paleoclimatic and tectonic implications
(Andean Geology, 2013-01)
The age of the Navidad Formation in central Chile has always been controversial, mainly due to the
conflicting age ranges indicated by its macro- and microfossils. Macrofossils are generally interpreted as having ...
