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.

I am a biologist working on diferent groups of fossils from Mexico. In 2008, I got this degree by the Universidad de Ciencias y Artes de Chiapas (UNICACH), Mexico, and actually I´m studying the Master´s degree in this same institution. My research interest is focused on the taxonomy and systematic of fossil fish from Cretacoeus localities of Chiapas. I have been working in the Museo de Paleontología "Eliseo Palacios Aguilera", collecting, preparing, and studying diverse groups of fossils.
María del Pilar Melgarejo-Damián. Posgrado en Ciencias Biológicas, Universidad Nacional Autónoma de México, Circuito de la Investigación S/N, Ciudad Universitaria, Delegación Coyoacán, Ciudad de México, 04510 México.
She has graduated with a Masters degree and is a young promising Mexican 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.
