Where: Marshall Islands (11.4° N, 162.4° E: paleocoordinates 10.0° N, 165.5° E)

• coordinate estimated from map

• small collection-level geographic resolution

When: Early/Lower Pliocene (5.3 - 3.6 Ma)

• STRATIGRAPHIC RELATIONS: From an undifferentiated lithostratigraphic unit. AGE: Early Pliocene, on the basis of foraminiferal biostratigraphy. STRATIGRAPHIC POSITION: A composite list from several beds within this section of drill core, from 500-600 ft.

• group of beds-level stratigraphic resolution

Environment/lithology: reef, buildup or bioherm; unlithified, shelly/skeletal carbonate

• ENVIRONMENT: Carbonate facies. Shallow water, presumably reefal. No paleoenvironmental data presented.
• LITHOLOGY: Limestone, buff, weakly cemented made up cheifly of corals, well preserved mollusks and forams (beach type). LITHIFICATION: Unlithified, on the basis of facies description and figured specimens.
