Saltasaurus, a dinosaur studied by José Bonaparte alongside Martín Vince and Juan C. Leal between 1975 and 1977, revealed evidence of armor plates called osteoderms. This discovery shifted understanding of late Mesozoic migration patterns between the Americas, positioning the researcher at the center of a significant scientific divergence regarding southern biota and the evolution of prehistoric species.
Early Development and Academic Path
Born in Rosario, Argentina, in 1928, José Fernando Bonaparte spent his formative years in Mercedes, Buenos Aires. Although he lacked formal paleontology training, he initiated his field efforts by gathering fossils with associates, leading to the establishment of a local museum. He eventually assumed a curatorial role at the National University of Tucumán, where he earned a Doctor honoris causa in 1974. Later, he served as a senior scientist at the Bernardino Rivadavia Natural Sciences Museum in Buenos Aires.

Bonaparte hypothesized a major migration of species between the Americas during the end of the Mesozoic era. His work examined the structural differences between northern and southern fauna, specifically focusing on how the separation of Gondwana influenced these prehistoric lineages. He is recognized as the first to define the abelisauridae, a classification for ceratosaurian carnivores that maintained dominance in Gondwana during the Cretaceous period.
Systematic Classification and Methodology
Throughout his career, Bonaparte maintained a traditional approach to research, avoiding modern cladistic methods for many years. He famously abstained from contributing to the 1990 publication The Dinosauria. By 2000, however, he began incorporating cladograms into his work, specifically regarding sauropods such as Ligabuesaurus and various proto-mammals found in Brazil. While his reputation rests on his extensive record of dinosaur discoveries, his personal preference remained the study of mammal fossils.
Mentorship and Institutional Recognition
Bonaparte influenced the discipline by mentoring several prominent paleontologists, including Rodolfo Coria, Luis Chiappe, Fernando Novas, Jaime Powell, Guillermo W. Rougier, Leonardo Salgado, Jorge Calvo, Sebastián Apesteguía, and Agustín Martinelli. His contributions were funded periodically by the National Geographic Society starting in the 1970s. He received the Konex Award in 1993, the Romer-Simpson Medal in 2008, and an honorary degree from the National University of Comahue in 2011. He died in his sleep in 2020.
