Well and outcrop samples are separated in different tables and ordered by geographic location from north to south. Benthic foraminifera and ostracodes indicative of deep-water deposition, and planktic foraminifera indicative of biostratigraphic age, are grouped separately in these tables. Foraminifera listed by previous authors are also indicated. Age and paleodepth interpretations of the samples are presented in Tables DR5 and DR6. Well samples were borrowed from ENAP and most were represented by micropaleontologic slides containing unmounted foraminifera that they had picked from washed residues of cuttings. We processed available core material as well as our outcrop samples using conventional techniques to isolate foraminifera and ostracodes. Some of the ENAP wells not only transected the Santo Domingo Formation but also a subjacent coal-bearing unit (see Geologic Setting). Some of its coaly intervals yielded internal molds of specimens that included those ascribed to the Eocene planktic foraminiferal genus Globigerinatheka by Finger and Encinas (2009). We extrapolated this by assigning an Eocene? age to all coaly intervals barren of these foraminiferal steinkerns, including those that had a few better-preserved Miocene specimens that were obviously caved downhole. 22 23
