José Fernando Bonaparte (born June 14, 1928), is an Argentine paleontologist who discovered a plethora of South American dinosaurs and mentored a new generation of Argentine paleontologists like Rodolfo Coria. One of the best known Argentine paleontologists,[1] he has been described by paleontologist Peter Dodson, "almost singlehandedly... responsible for Argentina becoming the sixth country in the world in kinds of dinosaurs".[2]

Biography[edit]

Bonaparte is the son of an Italian sailor, with no close connection to the Napoleon Bonaparte family. He was born in Rosario, Santa Fe, Argentina, and grew up in Mercedes, Buenos Aires. Despite a lack of formal training in paleontology, he started collecting fossils with many friends at an early age, and created a museum in their home town. He later became the curator of the National University of Tucumán, where he was named Doctor Honoris causa[3] in 1976, and then in the late 1970s became a senior scientist at the Museo Argentino de Ciencias Naturales in Buenos Aires. Bonaparte is a two-time Guggenheim Fellow[4] and since the 1970s has received periodic funding from the National Geographic Society.[1] He is reportedly hard working, stubborn, and has a strong personality, even violent.[5] He received another honorary degree from the National University of Comahue in 2011.[6]

Discoveries[edit]

Southern diversity[edit]

The supercontinent of Pangea split into Laurasia in the north and Gondwana in the south during the Jurassic. During the Cretaceous, South America pulled away from the rest of Gondwana. The division caused a divergence between northern biota and the southern biota, and the southern animals appear strange to those used to the more northerly fauna. Bonaparte's finds illustrate this divergence, and caused paleontologist Robert Bakker to dub him the "Master of the Mesozoic".[7]

In South America, the titanosaurs developed armor and flourished, while the sauropods of the northern continent were dying out and being replaced by vast herds of hadrosaurs; the carnivorous theropods were represented by abelisaurs and strange-looking dinosaurs like the horned, short-armed, and stub-nosed Carnotaurus. There are indications that a land bridge reunited North and South America during the Late Cretaceous because titanosaurs have been discovered as far north as Utah and duck-bills as far south as Patagonia.

Philosophy[edit]

Bonaparte was for a long time a traditionalist and did not use modern cladistic methods, which apply the principle of parsimony to a vast array of synapomorphies. Partly for this reason, he declined to work on the modern treatise The Dinosauria published in 1990. However, from 2000 Bonaparte began to use cladograms. For instance his studies of sauropods (e.g., Ligabuesaurus) and proto-mammals from Brazil, show cladograms made by himself and co-authors. While he is best known for his dinosaur discoveries, he prefers to study the fossils of mammals.[5]
