We wish to thank each of them for the help that was rendered. Our first acknowledgment goes to our respective institu- tions which provided us with the necessary means to make this meeting possible. Special thanks are extended to G. Arratia (University of Kansas), for her untiring assistance throughout the organization of the meeting. M. Newbrey (Royal Tyrrell Museum of Palaeontology) is acknowledged and thanked for de- signing and uploading the webpage of the meeting (http://www.ualberta.ca/~mnewbrey/MFMee- ting/index.html), that also includes useful information about Saltillo and the region. Information on this webpage was gathered and provided by C. Ifrim (Institute of Geosciences, Ruprecht- Karls-University), S. Giersh (State Museum of Natural History Karlsruhe), D. Brinkman (Royal Tyrrell Museum of Palaeontology), L. Espinosa-Arrubarrena (Instituto de Geología, Universidad Nacional Autónoma de México), A. Berrueto-Córdova, M. C. Aguillón-Martínez and C. R. Delga- do-de Jesús (Coordinación de Paleontología de la Secretaría de Educación y Cultura-Museo del Desierto), and the Secretary of Tourism of Coahuila. H.-P, Schultze (University of Kansas) and M. V. H. Wilson (University of Alberta) offered helpful revisions and comments concerning different aspects of the abstract book and Kathryn Mickle (University of Kansas) improved the style of some of the abstracts. Deep appreciation is expressed to Arturo H. González-González, Director of the Museo de Desierto for providing the installations and for his contribution to the welcome dinner; to the staff of the Museo del Desierto for giving assistance to the participants, conducting the museum tour, helping with the power point presentations and organizing the coffe breaks; to C. D. Luis Gil- Borja, former President of the University of Hidalgo and M.C. Octavio Castillo-Acosta, Director of the Instituto de Ciencias Básicas e Ingeniería, for providing financial support for the abstract book through the PIFI Program; to the personnel of the Publishing house Ediciones y Publica- ciones of the University of Hidalgo for their technical assistance with the preparation of the abs- tract book; to the Instituto de Geología de la Universidad Nacional Autónoma de México for facilities with the field trip to Tlayúa Quarry; and M. C. Perrilliat for showing the fish collection. We express our gratitude to the Aranguthy Family, Tepexi de Rodríguez, Puebla, for their hospitality during the field visit to the Tlayúa Quarry. We deeply appreciate the hospitality and collaboration of Lic. José Guadalupe Sánchez- Rangel, Major of General Cepeda, for offering the farewell dinner to the participants. Organizing committee THE FIFTH INTERNATIONAL MEETING ON MESOZOIC FISHES —DEDICATED IN THE HONOR OF SHELTON P. APPLEGATE The Fifth International Meeting on Mesozoic Fishes, which is taking place in the City of Saltillo, Coahuila, México, is dedicated to the memory of Dr. Shelton (Shelly) Pleasants Applegate (1928-2005). Shelly Applegate, a paleontologist for almost 50 years, spent his career working on a variety of different topics. As an undergraduate and graduate student, he investigated many groups of fossil plants and animals in his home state of Virginia, U.S.A. As a Ph.D. candidate at the Uni- versity of Chicago, he developed a keen interest in Mesozoic Fishes while investigating the Cre- taceous ichthyofauna of the Selma Formation from Alabama, U.S.A. For over 20 years, he collaborated with many universities and museums in the United Sta- tes (Duke, Chicago, Arkansas State, the Smithsonian Institution and the Los Angeles County Museum of Natural History, among others) where he studied marine mammals and bony fishes and developed several methods that were pivotal in the field of fossil shark teeth research. From 1976 to the unfortunate time of his death in 2005, Shelly worked for the Geological Institute at UNAM (National Autonomous University of México). In his “new” home, he started the study of fossil sharks (the Cipactli Group), triggered many investigations on Mexican dino- saurs, promoted many paleontological expeditions in Baja California, and most importantly, star- ted a research group dedicated to the study of Mesozoic fishes. His work in this field started with a project in southern México (State of Puebla) in a Cretaceous quarry called Tlayúa, the Nahuatl word for dawn. The discovery of the Tlayúa quarry in 1981 marked a new era in the study of fossil fishes in México. With time, this site has become the most important fossil locality in the country and in some respects it is unique to North America. The extraordinary kindness and love for México and its culture that Shelly demonstrated had a huge impact on paleontology in México—as evidenced by the collection of more than 6500 fossils from Tlayúa and the creation of the “Museo Regional Mixteco: Tlayúa” (the site museum that will be visited in one of the meeting’s field trips). The specimens from Tlayúa have greatly increased the collections at the National Paleontological Collection, UNAM, and include over 5000 Mesozoic fishes. For many of us Shelly was more than a fellow researcher and a friend; he was an enthusias- tic and passionate teacher. Without a doubt, he is considered the founder of “Mexican Paleoicht- hyology”. His keen interest in Mesozoic fishes (his presence at the Mesozoic Fishes meetings was emblematic), his sincere love for the Mexican countryside, and his appreciation for Earth Sciences, fiestas (parties), Tequila and Mezcal are still living in the new generations of Mexican paleoichthyologists. We want to thank and honor Shelly Applegate for all his instruction and friendship, and want to dedicate this Mesozoic Fishes Meeting to him. Luis Espinosa Arrubarrena & Katia A.
