This study analyzes the thematic and conceptual development of Brazilian Paleontology between 1940 and 2024, using a scientometric approach. Data were extracted from 1,465 PhD CVs registered on the Lattes Platform, totaling 31,670 studies and 91,922 keywords. The analysis was carried out in three periods: 1940-1969, 1970-1999, and 2000-2024. The study employed quantitative and qualitative methods, using tools such as OpenRefine, Table2Net, Gephi, and Brapci Bibliometric Tools to organize, analyze, and visualize the data. The results revealed a significant growth in scientific production throughout the periods. In Period I (1940-1969), research was initial, focused on palynotaxonomy and morphology, with Rio Grande do Sul and Pará as prominent geographic areas. Period II (1970-1999) showed significant growth, with emphasis on the Paraná Basin, sedimentology, and stratigraphy. Period III (2000-2024) showed the greatest increase, with a focus on systematics, taxonomy, and the use of molecular approaches. Keyword networks became denser and more complex over time, reflecting greater interdisciplinarity. Cluster analysis revealed distinct thematic communities, with a focus on Brazilian paleontological studies, ecology, biodiversity, and conservation. Research has evolved from a field with limited connections to a highly interconnected and diverse field. The study showed that the Lattes Platform is a valuable tool for analyzing the evolution of paleontology in Brazil, allowing the mapping of research trends and the consolidation of the field.
