Stratigraphic correlation of the Titanosarcolites Limestones (Late Maastrichtian) of the Central Inlier, Jerusalem Mountain Inlier, Maldon Inlier and Marchmont Inlier using Chiapasella radiolitiformis, C. aguilae, Parasarcolites monotubularis, P. baileyi, P. greeni, P. quadratus and P. atkinsoni. Modified after Mitchell and Gunter (2006).

... specimens previously named Titanosarcolites alatus at the UWIGM were attributed to the new genus Parasarcolites sp., specifically Parasarcolites atkinsoni (Mitchell and Gunter, 2006). One specimen figured as Antillocaprina occidentalis Trechmann (1924, pl. 25, fig. 1-3) was also placed in Parasarcolites atkinsoni because it had tubes. Parasarcolites spp. are also useful for stratigraphic correlation of the Late Maastrichtian (Figure 3) of the Central Inlier, Jerusalem Mountain Inlier, Maldon Inlier and Marchmont Inlier (Figure 1). A more primitive species, Parasarcolites sohli was subsequebntly described from Jamaica and Puerto Rico by ...

... Titanosarcolites Limestones crop out in seven inliers across the island of Jamaica. The rudist assemblages in these limestones have been extensively studied. Early use of rudists for biostratigraphic correlation (e.g., Chubb, 1971;Van der Wal, 1978;Rojas et al., 1996) was not very successful. Bed-by-bed collections and detailed analyses have now demonstrated that biozones can be recognized ( Mitchell and Gunter, 2002). This section looks at the use of the rudist collection of the UWIGM in biostratigraphic correlation studies of the Titanosarcolites Limestone in Jamaica. The use of Chiapasella will be discussed here. Chubb (1971) and Van der Wal (1978) attempted to subdivide the rudist limestones into biozones using rudists following Trechmann (1924). A study of the Logie Green section in the Central Inlier, Jamaica suggested that the lower part of the Titanosarcolites Limestone contained Praebarrettia sparcilirata (Whitfield). This matched the Stapleton Inlier, St. James, Jamaica (Chubb, 1971). Van der Wal (1978) studied the succession of Titanosarcolites in the St. James inliers and suggested that Titanosarcolites alatus Chubb was restricted to the lower part of the Carlton Hill and Maldon Limestones. These conclusions were also supported by Sohl (Sohl and Kollman, 1985;Sohl, 1998). Krijnen et al. (1993) and Mitchell (1999a), however, showed that P. sparcilirata occurred in the middle part of the Guinea Corn Formation at Logie Green and in the Rio Minho between Grantham and Guinea Corn, whereas Mitchell and Gunter (2006) Mitchell and Gunter, 2002, see Mitchell and Pons, 2010) are important for local and regional correlation and can be used to subdivide the Titanosarcolites Limestones into two biozones (Figures 3-4). A third species, Chiapasella cubensis Rutten (Figure 4), has been identified in the Back Rio Grande area in eastern Jamaica ( Mitchell and Ramsook, 2009). Specimens of these species are housed in the UWIGM as part of the rudist collection ( Table 1). The type specimens of C. radiolitiformis are in the British Museum whereas the type specimen of C. aguilae is in the Texas Memorial Museum (Mitchell and Pons, ...
