Resumen
El Chocón is a key site in the history of Argentine paleoherpetology, since the area where it is located has provided important discoveries, including one of the earliest findings of a fossil reptile for Argentina at the end of the 19th century. The “Ernesto Bachmann” Museum of Villa El Chocón is an institution that —although it was created recently— has managed to form a stable work team that has made important contributions to the knowledge of fossil vertebrates from the Cretaceous of Patagonia. In the present work, a brief historical review of the local paleherpetological records is made as well as the main actors involved both in the scientific projects and creation and development of the Museum over time.

Resumen
The history of Argentinean women in the development of paleoherpetology is very interesting and crucial, evidencing the role of women in the academic field, in the family environment, and the society. Throughout almost 100 years, the investigations carried out by women have been increasing, covering the main taxonomic groups and generating new lines of research with each generation. At present, the paradigm shift of women in the field of vertebrate paleontology in general is not only reflected in their leading role in paleontological field trips and research teams but also in their management activities and their professional development in the international scientific community.

Resumen
Mendoza Province is an Argentinean area that has yielded numerous herpetological fossils. From an historical viewpoint, the Museo Moyano has played an important role, especially between 1937 and 1968, when the naturalist Carlos Rusconi was the institutional director. C. Rusconi collected a great number and variety of fossils in the Cuyo region, and defined a lot of new taxa, including several genera and species of amphibians and reptiles. Most of them are Triassic and Jurassic taxa, but also some Cenozoic forms. Since C. Rusconi resigned as the director, no more paleontological research has been done from the museum, but its collections has been reviewed and increased. From 1970s onward, C. Rusconi’s taxa have been object of taxonomic revisions; even though many resulted to be nomina dubia, others were confirmed as valid taxa. A later significant contribution to the museum collection of fossil reptiles came from an inter-institutional fieldwork season to the south of the province in 1996, among members of the Museo Moyano, the Museo de Ciencias Naturales of San Juan, and the Chicago University (USA), which gave place to the discovery of Cretaceous dinosaur remains. Sporadically, different specimens from the Triassic of Cacheuta-Potrerillos area and even from the late Oligocene of southern Mendoza have been posteriorly incorporated. At present, the Paleovertebrate collection of the Museo Moyano was incorporated to the National System of Biological Data and to the international network Global Biodiversity Information Facility.

Resumen
The Facultad de Ciencias Exactas y Naturales (FCEN) of the Universidad de Buenos Aires (UBA) was originally located in the area of the Buenos Aires downtown known as the Manzana de las Luces and then was relocated to the buildings I and II of Ciudad Universitaria. The paleoherpetological studies in this institution began with the contributions of Dr. Osvaldo Reig, who was at UBA in three separate periods: first in the early ’50s, then during the earlies and mid ’60s, and finally in the mid ’80s. During his first period his research was focused on Triassic archosaurs and anurans from the Mesozoic and Cenozoic. On his second period at FCEN, his research was focused towards microevolutionary studies based on extant species. Dr. Ana María Báez is a specialist in fossil anurans, who had a high impact on the field and formed several students and acted as a professor at FCEN up to 2006. After A. M. Báez retired from her teaching duties, her place was filled by her disciple Dr. Claudia A. Marsicano. Dr. C. A. Marsicano centered her early studies on fossil temnospondyls to later expand her focus to the analyses of Permo-Triassic tetrapod faunas of Gondwana. C. A. Marsicano founded the Laboratorio de Estudios Paleobiológicos en Ambientes Continentales and has acted as advisor in several undergraduate and doctoral theses. The younger paleoherpetologists of the FCEN are Dr. Juan M. Leardi, whose research focuses in fossil crocodylomorphs, and Dr. Raúl O. Gómez, who studies fossil anurans and other vertebrates.

Resumen
This contribution summarizes the history of paleontology in the Mesozoic sediments of the San Luis Province, as well as historical reviews of how the first activities related to the creation of a museum arise. The first findings in this province were made in the 1940s approximately, with the discovery of dinosaur footprints and later in 1963 the discovery of fragile bones. When the renowned paleontologist José Bonaparte managed to identify these bones as belonging to pterosaurs, a series of explorations were triggered in the region, revealing the first pterosaur for Argentina. From 1990 onward, Luis M. Chiappe conducted fieldwork in the Lagarcito Formation and collected hundreds of pterosaur specimens. From these investigations, a heritage emerged that would constitute the future basis of an important collection of fossil pieces, resulting in the best collection in the world of a single species of flying reptile, including its different ontogenetic stages. Here, the most important findings for this flying reptile from San Luis are summarized, as well as the first archosauriform remains from Triassic sediments. Throughout this report, we can appreciate the young paleoherpetological history of San Luis.

Resumen
Paleoherpetological studies conducted in the city of Mar del Plata began in the mid-1990s, and have been consolidated and sustained since 1998 onward with the creation of a paleoherpetological research group at the Universidad Nacional de Mar del Plata. The greatest research activity carried out in this institution was focused on squamates (lizards, snakes, and amphisbaenians). The paleontological collection of the Museo de Ciencias Naturales “Lorenzo Scaglia” has also been very relevant in the development of the paleoherpetology research in the region with the contribution of outstanding materials of amphibians, pterosaurs, crocodiles, and birds that were studied by researchers from other institutions of the country.

Resumen
We briefly comment on the main historical background of the Argentinian Paleoherpetholgy and main discoveries (anurans, testudines, plesiosaurs, ichthyosaurs, mosasaurs, non-avian and avian dinosaurs) carried on by research groups that included Argentinean scientists are summarized. Due to the extensive data, a detailed description of each contribution is unpractical. Thus, we provide a bibliographic detail that will allow to the reader deepen into any of the fields according to their interests.

Resumen
Studies carried out on fossil reptiles housed in the collections of the “Prof. Dr. Juan A. Olsacher” museum in the city of Zapala (Neuquén) have been oriented towards marine and continental forms of the Jurassic and Lower Cretaceous and lower Upper Cretaceous of the Neuquina Basin. In association with the Dirección Provincial de Minería from its origins, the Olsacher Museum provided logistical collaboration to national and international research groups, including the marine reptiles group of the La Plata Museum. Since 2008, the museum has been in charge of studying the geological and taphonomic context of the fossil remains found. As a result of the fieldwork carried out over the last 50 years, which had the logistical support of the Olsacher museum, the institution has incorporated into its collections a large number of specimens, including 15 holotypes, 7 of them are marine reptiles and 8 are dinosaurs.

Resumen
The Vertebrate Fossil Laboratory (LVF) of the Miguel Lillo Institute at the National University of Tucumán started in 1957 with the initial drive of Osvaldo Reig, who was its first Director and Curator of the Lillo Vertebrate Paleontology (PVL) collection. José Bonaparte, initially incorporated as technician, was the Director of the LVF from 1960 to 1978, after Reig. These researchers, together with Rodolfo Casamiquela (then at the La Plata Museum), dramatically altered the knowledge of argentinean Mesozoic amphibians and reptiles during the decades of 1960s and 1970s, representing the onset of a new chapter for the argentinean paleontology. During that time, these researchers described 34 new species and collected several fossil specimens from Mesozoic outcrops of different regions of Argentina. This activity enriched the PVL, resulting in a key collection for the study of Triassic paleoherpetology, a relevance that continues today. Jaime Powell took over the LVF after Bonaparte and conducted intensive research, mostly on sauropod dinosaurs from Argentina. Paleoherpetological research was complemented by an important team of technicians and artists who, in addition to fieldwork and fossil preparation, mounted fossil skeletons, made sculptures and life reconstructions of the Mesozoic fauna. Nowadays, the Lillo community has an important and dynamic group of researchers, mostly focused on the study of Cenozoic mammals.
