^*Manuel Juncal is currently a PhD student at University of Vigo. He graduated in mining engineer at the University of Vigo (2014) specializing in environment and mining. His research focuses on the Permian palynostratigraphy from Iberian Peninsula. He is also strongly interested in Carboniferous and Triassic Palynology and their use in basin analysis.
^**José B. Diez works on several aspects of palaeobotany. His research is focused on taphonomy, biostratigraphy, palaeogeography, and palaeoclimatology. He graduated from the University of Zaragoza (Spain), where he also obtained his PhD in geological sciences. In addition, he received a PhD in palaeobiology from the University Pierre et Marie Curie, Paris-6 (France). Since 2001 he has held a teaching position at the University of Vigo.
^***Raúl De La Horra obtained his PhD in geological sciences at the Complutense University of Madrid (Spain), where he holds a teaching position since 2010. His current research is mainly focused on sedimentology, basin analysis and paleosoils of Permian and Triassic continental sedimentary basins of Western Europe.
^****Belén Galán-Abellán obtained his PhD in geological sciences at the Complutense University of Madrid (Spain) in 2011. Her research focuses on the sedimentology and stratigraphy of Permian and Triassic continental deposits, mainly in the Iberian and Catalan Ranges. Recent research studies include development of minerals under extreme conditions.
^*****Violeta Borruel-Abadía is currently a PhD student at Complutense University of Madrid. She graduated in geology at the University of Zaragoza (2011). Her research focuses on the Permian and Triassic continental deposits, especially of the Iberian Ranges, from a multidisciplinary point of view (covering stratigraphy, sedimentology, mineralogy and paleontology).
^******José F. Barrenchea obtained his PhD in geological sciences at the Complutense University of Madrid (Spain), where he holds a teaching position since 1994. His current research is focused on the relationship between mineralogy/geochemistry and palaeoenvironmental conditions in Permian-Triassic continental sedimentary basins.
^*******Alfredo Arche obtained his PhD in geological sciences at the Complutense University of Madrid (Spain). He later obtained a permanent position as researcher in the National Research Council of Spain (CSIC). As a visitor, he stayed different times at Oxford University (UK). His current research is focused on basin analysis and relationship between tectonics and sedimentation.
^********José López-Gómez obtained his PhD in geological sciences at the Complutense University, Madrid, Spain. In 1990 he obtained the presentday research position in the National Research Centre (CSIC) where his research is mainly focused on the tectonic and sedimentation relationship in continental and marine Pemian-Triassic basins of Western Europe.
