^**Fatima Praxedes Rabelo Leite is currently a postdoctoral fellow at the Universidade Federal de Mato Grosso, Brazil. She earned her bachelor' s degree in biology from the Universidade Santa Ursula in 1990 and her master's degree is in sedimentary geology, awarded by the Universidade de São Paulo in 1997. Fatima then obtained a PhD from the Universidade Federal de Brasília in 2006. She has undertaken two postdoctoral contracts at the Smithsonian Tropical Research Institute, Panama in 2007 and 2010/2011. Fatima' s research is on the Neogene biostratigraphy, palaeoecology and palynology of Amazonia.
^***Jackson Douglas Silva Da Paz is a lecturer at the Universidade Federal de Roraima, Brazil. He earned his bachelor' s degree in geology from the Federal University of Amazonas in 1998; his master's degree was awarded by the Universidade Federal do Pará in 2000.
