“…In the Caribbean Gelasian deposits in Curaçao, Jamaica, Costa Rica, and Panama, no Acropora- dominated facies were recorded ( 64 ). Acropora- dominated deposits have been recorded from the Gelasian (2.6 to 1.8 Ma) in the Dominican Republic ( 65 ) and Panama ( 64 ).…”

“…24.7 Ma, facies attributed to the Montebello Member continued to be deposited, although the entire age range is unknown because of the lack of sampling of the upper part of the Montebello Member.

“…All units studied in this time interval are characterized by abundant red algae, benthic foraminifera (e.g., miliolid and soritid foraminifera), mollusks, echinoids, and bryozoans, especially in basal and middle portions of the units. Significantly, the lower to middle parts of the units lack abundant photosynthetic biota, including warm-water corals (Monroe 1980;Seiglie and Moussa 1984;Braga et al 2012). During the Burdigalian-early Serravallian, there was a global increase in productivity based on a long-term shift toward higher d 13 C values (Vincent and Berger 1985), and upwelling continued to be a major process affecting the Caribbean (Maurrasse 1993; Edinger and Risk 1994;Mallinson et al 1994;Halfar and Mutti 2005; fig.…”

“…Upper portions of the Aguada (Los Puertos) Limestone, the Aymamón Limestone, and the Ponce Limestone in Puerto Rico and the middle to upper portions of the Yanigua-Los Haitises Formations show the reappearance of photosynthetic corals that are tolerant of cool, turbid water conditions (e.g., Goniopora, Porites, Agaricia,a n dMontastraea genera; Edinger and Risk 1994;Ward et al 2002; q19 Ortega-Ariza and Franseen 2011; Braga et al 2012). These corals are interpreted to have formed as reef flats, fringing reefs, and small patch reefs (Monroe 1980;Braga et al 2012). Timing of the coral development appears to be generally coeval in the studied units in Puerto Rico (ca.…”

“…The Puerto Rico and Dominican Republic samples that show depleted d 13 C values are from the San Sebastian Formation, the Montebello Member, the Ponce Limestone, the Cercado Formation, and the Yanigua-Los Haitises Formations (tables 1, 2). These lithologic units represent fluvial, coastal lagoon, and nearshore to inner shelf environments (Monroe 1980;Seiglie and Moussa 1984;Iturralde-Vinent 2001;Maier et al 2007;McNeill et al 2012;Braga et al 2012; fig. 2).…”

87 Sr/ 86 Sr-derived mean ages from low-Mg calcite Kuphus incrassatus and Ostrea haitensis bivalves provide an updated and refined chronostratigraphy for selected Oligocene-Miocene carbonate and siliciclastic units in Puerto Rico and the Dominican Republic. Results indicate ages of middle to late Oligocene for the San Sebastian Formation (ca. 29.78-26.51 Ma), the Lares Limestone (ca. 26.51-24.73 Ma), and the Montebello Member (ca. 27.30-24.10 Ma); q3 middle Miocene to the early part of the late Miocene for the Cibao Formation (ca. 12.17 Ma), the Aguada (Los Puertos) Limestone (ca. 14.67-11.14 Ma), and the Aymamón Limestone (ca. 10.98 Ma) in northern Puerto Rico as well as for the Ponce Limestone (ca. 14.97-9.84 Ma) in southern Puerto Rico and the Yanigua-Los Haitises Formations (ca. 15.75-12.58 Ma) in northeastern Dominican Republic; and late Miocene for the Cercado Formation (ca. 6.31-5.88 Ma)in northwestern Dominican Republic. These results show some significant modifications to previous chronostratigraphic studies. The San Sebastian Formation marks the last major input of siliciclastics in Puerto Rico. The Lares Limestone is characterized by a diverse warm-and cool-water coral assemblage, whereas the Montebello Member is characterized by large benthic foraminifera and mollusks, which likely indicates differences in depth of deposition or environments that were differentially influenced by upwelling. The ultimate disappearance of warm-water corals in the late Oligocene coincides with the end of global warming and coral extinction events. The Cibao Formation, the Aguada (Los Puertos) Limestone, the Aymamón Limestone, the Ponce Limestone, and the Yanigua-Los Haitises Formations are predominantly composed of shallow marine deposits consisting of red algae, mollusks, small benthic foraminifera, and cool-water corals in the upper parts. These characteristics are consistent with an upwelling control, which has been documented as a regionally important process in the Caribbean during that time. The reappearance of corals indicates an environmental change that coincides with closure of the Central American Seaway. The closure resulted in circulation changes, warm temperatures, and low nutrients in the Caribbean, which created suitable conditions for diverse coral reef development, as exemplified by the Cercado Formation.

Baripada Marine Beds (BMB) have been studied extensively in terms of its mega fossil content. However, not much has been discussed about the foraminiferal content and the organic matter assemblage in these beds. The fossiliferous sequence of BMB consists of sandstone, shale and limestone units. The present study is persued on the limestone unit of BMB. Foraminiferal, thin section and rock-eval pyrolysis studies were performed on the 33 surface samples collected from five sections of Jamdapal and Mukurmatia region along the Budhabalang river bank. Foraminifera are less abundant in the samples of Jamdapal, whereas Mukurmatia is comparatively rich. First appearance datum of Globorotalia menardii[ranges since middle Miocene (12.6 Ma); FAD at planktic foraminiferal zone N12] and last appearance datum of Neogloboquadrina continuosa [ranges between early Miocene (23.2 Ma) to late Miocene (8.3 Ma); FAD at planktic foraminiferal zone N4B and LAD at N16] together suggest that the limestone unit was deposited in between 12.6 to 8.3 Ma within the upper Miocene. Also, the association of shallow water benthic foraminifera (Species of Ammonia, Asterorotalia, Bolivina, Buliminella, Cibicides, Challengerella, Criboelphidium, Cribononion, Elphidium, Hanzawaia, Nonionella) and planktic foraminifera (Globigerina falcoensis, Globigerina woodi, Globorotalia menardii, Neogloboquadrina continuosa) together with oyster bank and shark teeth suggest deposition of limestone within well oxygenated, tropical, shallow water, open marine condition (within 40m water depth). Lithological and thin section studies together with global sea level fluctuation history advocate that upper Miocene marine transgression promoted the formation of this unit. Bulk organic geochemical data obtained by the rock-eval pyrolysis studies on selected samples indicate a low total organic carbon (TOC), with low hydrogen index (HI), high oxygen index (OI). The organic facies is characterised by type-IV kerogen with major contribution from near shore terrestrial plants. This also suggests deposition in shallow, oxygenated environments that did not promote significant accumulation and preservation of organic content in sediments.
