Jorge Villegas Martín received his B.S. from the La Havana University in 2009, and his M.S. (2014) and a D.S. (2019) from the Unisinos University, Brazil. His research interests focus on invertebrate ichnology and its application to sedimentary geology, paleobiology, and as bioindicators of paleoecological and paleoenvironment changes. Villegas-Martín is particularly interested in the ecology of benthic invertebrates, and how these communities have been affected by paleoenvironment conditions. He has conducted field research mainly in southern Brazil and Cuba, but has also participated in field studies in other regions of the world. Villegas-Martín began working with ichnology around 2009, focusing on the characterization of invertebrates trace fossil and paleoecological analyses. He later broadened his interests to include ichnological applications to stratigraphy, petroleum geology, and paleoenvironment changes. Currently, Villegas-Martín is a researcher in the Technological Institute of Paleoceanography and Climatic Changes – itt OCEANEON at Unisinos University.

Renata Netto received her B.S. from the Unisinos University in 1984, and her M.S. (1989) and a D.S. (1994) from the Federal University of Rio Grande do Sul, Brazil. Her research interests have focused primarily on invertebrate ichnology and its application to sedimentary geology and, more recently, as bioindicators of climate changes. Netto is particularly interested in the ecology of benthic and edaphic invertebrates, and how these communities have been affected by glaciation cycles. She has conducted field research mainly in southern Brazil, but has also participated in fieldwork around the world. Netto began working with ichnology around 1981, focusing on invertebrates, trace fossil characterization and paleoecological and paleoenvironmental analyses, and soon broadenedcher interests to inlcude ichnological applications to stratigraphy, petroleum geology, and climate changes. Since 1994, Netto has been a Full Professor in the Geology Graduate Program at Unisinos University.

Reinaldo Rojas Consuegra holds a degree in geological engineering from the State University of Azerbaijan (1986), a Master's degree in Geology from the University of Pinar (2001) and a PhD in Geological Sciences from the Polytechnic University of Havana (2004). Rojas-Consuegra began his work as a geologist-cartographer at medium to regional scales in Cuban territory (1986-1990). He was for a researcher and curator at the MNHNC a long time (1990-2015). His research interests include stratigraphy, invertebrate paleontology and studies of the Cretaceous-Paleogene boundary. He is currently a senior researcher at the Petroleum Research Center in Havana, Cuba.
Jordi M. de Gibert. Deceased on September 23, 2012.
Jordi M. de Gibert (1968-2012) was graduated in Geology from the Barcelona University (1986/1987), Spain. He continued his education and developed his M.S. (1992) and a D.S. (1995) at the Barcelona University. He was an outstanding geologist, paleontologist and ichnologist, as well as a remarkable teacher and communicator. Both in his personal life and as a scientist, Jordi was always willing to share and disseminate his knowledge, and enriching his ideas and projects with the new input coming from his colleagues. He loved the world of paleontology and ichnology, for which he became a passionate supporter of our research and our community. He was dedicated to the study of trace fossils, both from a paleobiological approach and from the point of view of their relationship with sedimentary facies and their use for paleoenvironmental interpretation.
