Where: Trinidad and Tobago (10.6° N, 61.1° W: paleocoordinates 10.5° N, 59.6° W)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Melajo Clay Member (Springvale Formation), Late/Upper Miocene (11.6 - 5.3 Ma)
• The Melajo Clay Member of the Springvale Formation is correlated with the Savaneta Glaconitic Sandstone Member of the Springvale Formation, although part of it may be younger. The Melajo fauna is late Miocene in age. The Melajo Clay rests transgressively on the phyllites of the Northern Range with a basal conglomerate of about 1 m thickness. The conglomerate graes into a 1.5 m thick limestone, which is overlain by a bed of sand of about 1 m thickness. Above the sand is the Melajo Clay. The total thickness of the Melajo Clay is about 200 ft. It is unconformably overlain by Pleistocene sand and gravel deposits.
