Book of Abstracts of the Turtle Evolution Symposium 2021

The main goals of the “Turtle Evolution Symposium 2021” (TES 2021) are: to present, promote, communicate, and discuss the latest advances and original results about the evolutionary history of turtles, since their origin and early evolution until the present. It is an international meeting that gathers all turtle researchers and students around the world that work in specific topics like anatomy, evolution, nomenclature, taxonomy, phylogenetic relationships, fossil record of extinct turtles, conservation, among others. TES 2021 is the seventh meeting since 1983 and the second in South America. In the last decades TES acquired certain regularity and it is organized each 3 years. In this TES 2021, we honor Dr. Marcelo S. de la Fuente. Dr. de la Fuente is the first researcher in South America dedicated to the study of extinct turtles and who marked a before and after in our discipline at regional level whose studies reached a global impact. The election of Argentina as the place to organize TES 2021 is the result of the ongoing growth of paleoherpetology in the country during the last decades. Nowadays, the country accounts for more than 400 occurrences and more than 40 species of extinct turtles, being the most rich and important record of turtles in South America and one of the most important and extensive in the world.
