The northern boundary of Puerto Rico is marked by the kilometer-long Puerto Rico Trench, which is the deepest part of the Atlantic Ocean, with a maximum depth of 8, meters (Figure 1). It is the eighth deepest trench in the world and the deepest seafloor outside the Pacific Ocean.

The consistent orientation of the St. Croix and St. Croix Ridge fracture system implies a tensional rudists of this type is Puerto Rico (H. Santos, pers. commun., ). Seismicity Seismic activity today is detectable only in the shallow zones in the north wall from 0 to 50 km deep. Foraminifera are used to find petroleum Some species are geologically short-lived and some forms are only found in specific environments.

Therefore, a paleontologist can examine the specimens in a small rock sample like those recovered during the drilling of oil wells and determine the geologic age and environment when the rock formed. Recognition of closely spaced bio-events is also useful for biosteering of directionally-drilled oil-and gas-wells.

This foraminifera was collected as it floated about 3 meters below the surface off the coast of Puerto Rico. The central dark area is the shell surrounded by spines. The tiny yellow dots are symbiotic algae, which live in the protoplasm of the host organism. Foraminifera typically produce a test, or shell, which can have either one or multiple chambers, some becoming quite elaborate in structure.

These shells are commonly made of calcium carbonate (CaCO 3) or agglutinated sediment particles. O species are recognized, both living (10,) and fossil (40,). They are usually less than 1 mm in size, but some are. Additional Physical Format: Online version: Galloway, J.J. (Jesse James), Tertiary Foraminifera of Porto Rico.

New York, The Academy, Planktic and smaller benthic foraminifera are prepared by crushing the sample into roughly five millimeter fragments. The crushed sample is then placed in a strong glass beaker or similar vessel and water and washing soda or 6% hydrogen peroxide added, left to stand and then heated and allowed to simmer.

The richness of mammals in Puerto Rico, like many other islands, is low relative to mainland regions. The present-day native terrestrial mammal fauna of Puerto Rico is composed of only 13 species, all of which are bats. 18 marine mammals, including manatees, dolphins and whales, occur in Puerto Rico.
