The Caimito Formation (Tcm)Geologic Map, 1980 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.[https://paleobiodb.org/classic/displayStrata?geological_group=&formation=Caimito&group_formation_member=Caimito Caimito Formation] at Fossilworks.org 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.Woodring, 1957, p.28
