Extract

Beds of shale, sandstone and conglomerate containing Upper Cretaceous fossils occur at several places in Jamaica, and in every instance that I know of they are found to be more or less in close association with Rudist limestones. They generally occur below the limestones with Rudistae but in at least one locality, that at St. Ann's Great River, fossiliferous shales occur immediately above and also a considerable distance, 1,000 feet or so, below a bed of Rudist limestone.
