The Caimito Formation (Tcm)[1] is a geologic formation in Panama. The marls, sandstones and conglomerates preserve bivalve and gastropod fossils dating back to the Late Oligocene to Early Miocene period.[2] The name Caimito was proposed by MacDonald in 1913, named after the Caimito junction in the Panama Railroad during the construction of the Panama Canal.[3]
