Antonio Snider Pellegrini

Antonio Snider-Pellegrini (1802–1885) was a French geographer and scientist who theorized about the possibility of continental drift, anticipating Wegener's theories concerning Pangaea by several decades.

In 1858, Snider-Pellegrini published his book, La Création et ses mystères dévoilés ("The Creation and its Mysteries Unveiled"). He suggested that all continents were once joined during the Pennsylvanian Period. This theory was grounded in his discovery of identical plant fossils in both Europe and the United States, with matching fossils found across all continents.
