“…Uranium‐series dating may be used in deposits as old as ca 500 kyr. Less precise dating techniques include amino acid racemization (Miller & Brigham‐Grette, ) and electron spin resonance (Schellmann & Radtke, ; Schellmann et al ., ) reaching back 200 to 300 kyr bp , respectively, as well as Sr isotope dating (Farrell et al ., ; McArthur et al ., ), calcareous nannoplankton biostratigraphy (Raffi et al ., ) and magnetostratigraphy (McNeill, ), which push this threshold beyond 500 kyr.…”

The tropical-subtropical western Atlantic realm harbours abundant fringing reefs, two major barrier reefs (Belize, Florida), several atolls and large reef-fringed carbonate platforms (Bahamas). Data from Belize and south Florida indicate that major barrier reefs were established during the high sea-levels of the long and warm marine isotope stage 11.

Elevated terraces and outcrops of reefs of the last interglacial of marine isotope stage 5e are evidence of higher than present sea-level and temperature that sustained large reef-fringed carbonate platforms and ramps in the Florida-Bahamas region and central America (Belize, Mexico), including ooid deposition in warm and shallow waters. During the highstands of marine isotope stages 5c and 5a, at sea-levels several metres lower than today, fringing reefs developed in parts of the Caribbean, for example, in south Florida (′outlier reefs′). Data from the island of Barbados support the contention that the postglacial sea-level rise from about -120 m was rapid and punctuated by two meltwater pulses Ia and Ib, which bracket the beginning and end of the Younger Dryas, respectively. After reflooding of shelves in the early Holocene, reefs developed preferentially on highs of the underlying karstified Pleistocene limestone surface and on former river channel bars. Many reefs in the western Atlantic region kept pace with Holocene sea-level rise whereas some were drowned. Reasons for reef drowning are debated and include sea-level rise, elevation of antecedent topography, and deterioration of environmental conditions such as high nutrient input. Apart from sea-level and antecedent topography, factors such as exposure to waves and currents, storms, and sedimentation have controlled reef development. The historical decline of acroporid corals in the Caribbean realm has been attributed to cooling following the Holocene thermal optimum; however, historical die-offs of reef-building corals and other reef organisms suggest that some if not all recent declines were unprecedented during the Holocene. Rising temperatures, decreasing carbonate saturation, increased frequency of major storms, high nutrient concentrations and sedimentation, overfishing, and diseases certainly played a role in decline, but systematic studies relating these environmental factors to Holocene reefbuilding are only in the beginning stages.

“…Pleistocene carbonate terraces unconformably overlie Neogene carbonates; these Pleistocene terraces make up the bulk of the carbonate terrace exposed at the surface, with progressively younger terraces found seaward.(e.g. Alexander, 1961;De Buisonje and Zonneveld, 1976;Fouke et al, 1996;Schellmann et al, 2004) (Fig 1).…”

originated the idea of a problem focused microfossil conference and he was the primary driving force during the conferences early planning until his untimely passing in May of 2004. At that time a group of Garry's colleagues carried forward his wishes for the conference through to its successful completion. More than 150 participants from 20 countries registered for the conference, and over 90 oral and poster sessions were given during the three formal days of the conference. In addition, 22 corporate and institutional sponsors donated to ensure the success of this event. After expenses, the remaining funds were passed on to SEPM, which placed the funds in the Garry Jones Memorial Grant for student research. The fund was established in Garry's memory to honor his contributions to micropaleontology. Grants are awarded from the fund to students conducting research with a substantial micropaleontological component and it is administered by the North American Micropaleontology Section (NAMS) of SEPM.
