Born in 1966 in Zacatecaz, in 1998, I got the Bachelors degree (Biology) in the Sciences Faculty at Universidad Nacional Autónoma de México (UNAM). In 2005, I got my Doctoral degree in the Geological Institute (IGM), UNAM. During 2005-2007, I had a Posdoctoral position in the Biological Institute at Universidade do Estado do Rio de Janeiro, Brazil. Always I worked on Mexican fossil fishes under my advisor and friend Dr. Shelton P. Applegate. Since 2007, I´m in charge of the Tlayúa project as full-time Researcher at IGM, UNAM. The main interest of my work is focused on the taxonomical characterization of Mexican fossil vertebrates and the understood of phylogenetic and biogeographic patterns and process outlined on these fossils.

In 2012, he graduated as a Biologist at the Facultad de Estudios Superiores Iztacala of the Universidad Nacional Autónoma de México. His Bachelor´s degree Thesis provided the preliminary studies on the pliosaurids of the Sabinal formation (Upper Jurassic) of south of Mexico. Currently, he is enrolled in a Master´s studies of the Programa de Posgrado en Ciencias Biológicas of the UNAM, in which he is addressing the taxonomic identification of all the Late Jurassic reptiles from the Tlaxiaco Basin. He is an active member of the team formed to develop projects of exploration, collection, and study of the marine and freshwater fossil vertebrates from Mexico, which are currently in process and led by Jesús Alvarado-Ortega.

He is an enthusiastic paleontologist. In 1979, he graduated as a Biologist at the Facultad de Ciencias of the Universidad Nacional Autónoma de Méxicoo and as Master in Sciences by California State University, Long Beach, in 1987. Although, initially his main scientific work was focused on fossil sharks, his partnership with different Mexican and foreigner researchers involved him in the other paleontological fields. Together with Shelton Pleasant Applegate, with whom he shared a passion for sharks, discovered the first Mexican Konservat-lagerstätte locality, the Tlayúa quarry. However, his greatest contribution has been to be an important participant in the advice and teaching of young and new paleontologists. Currently, he is the Head of the Museo de Geología (UNAM), where constantly he participates and promotes the diffusion and divulgation of the Earth Sciences. Also, he is a rock-star and singer of the Jurassic- Band.

She is a Masters degree graduated and a young Mexican promising paleontologist. She received her degrees from the Universidad Nacional Autónoma de México (UNAM). During the bachelors, Pily used different statistical tools to develop a comprehensive quantitative framework to assess the taxonomical diversity of Pleistocene horses in Mexico. During her Masters, she worked on the morphological diversity of the ellimmichthyiform fishes supported in multivariate analyses. Pily has been a main participant in the projects of her advisor (Jesús Alvarado-Ortega), in the prospection and collection of vertebrates in different localities in Mexico as well as in the application of new analyses to characterize the taxonomical diversity and of Mexican fossils and their evolutionary processes and ontogenetic development.
