Cucaracha Formation (Panama)

The Cucaracha Formation (Tca)^[1] is a geologic formation in Panama. It preserves vertebrate and plant fossils dating back to the Neogene period; Early to Middle Miocene epochs (Hemingfordian).^[2] Fossils of the crocodylian Centenariosuchus, the turtle Rhinoclemmys panamaensis and the artiodactyl Paratoceras have been found in the formation.^[3]

The Cucaracha Formation is approximately 125 metres (410 ft) thick,^[4] and dated to 19 to 14 Ma.^[5]
