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]
