Caimito Formation
The Caimito Formation (Tcm) 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. 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.
