Adán Pérez-García is a researcher at the Evolutionary Biology Group of the National University of Distance Education (UNED, Madrid, Spain), and a Senior Lecturer at the Faculty of Sciences of that University. His main field of research corresponds to the study of the evolutionary history of the turtles, both European forms and taxa related to them that inhabited other continents, especially Africa. He focused on the study of several Mesozoic turtle lineages during the development of his PhD Thesis (presented in 2012), currently working in the study of the systematics, paleobiogeography and diversity of both Mesozoic and Cenozoic forms. He has directed several national and international research projects that involved the analysis of reptile faunas, especially from the Mesozoic. He is the author of more than 150 scientific papers in SCI journals, and more than 300 contributions presented in specialized scientific conferences. He has described more than 35 new genera and about 40 new species of reptiles, most of them turtles, but also crocodiles and sauropterygians.
