AbstractThe Middle Eocene to Middle Miocene White Limestone Group of Jamaica contains a common and diverse, poorly to well-preserved microboring ichnofauna, namely Centrichnus eccentricus Bromley & Martinell, Curvichnus pediformis isp. nov., Dendrorete balani Tavernier, Campbell & Golubic, Dipatulichnus rotundus Nielsen & Nielsen, Entobia volzi Bromley & D’Alessandro, Entobia isp. cf. E. ovula Bromley & D’Alessandro, Entobia isp. forms A and B, Fossichnus solus Nielsen, Nielsen & Bromley, Maeandropolydora elegans Bromley & D’Alessandro, Maeandropolydora sulcans Voigt, Oichnus asperus Nielsen & Nielsen, Oichnus excavatus Donovan & Jagt, Oichnus gradatus Nielsen & Nielsen, Oichnus ovalis Bromley, Oichnus paraboloides Bromley, Oichnus simplex Bromley, Oichnus isp., Planobola microgota Schmidt, Podichnus centrifugalis Bromley & Surlyk, Ramosulcichnus biforans Hillmer & Schulz, Reticulina elegans Radtke, Scolecia filosa Radtke, Scolecia maeandria Radtke, Stellatichnus radiatus Nielsen & Nielsen, Trypanites fimbriatus (Stephenson), Trypanites solitarius (Hagenow), Trypanites weisei Mägdefrau, and one example each of an unnamed crescent-shaped and a sub-horizontal to undulatory boring. These ichnospecies are distributed within three formations, the Somerset, Moneague and Montpelier formations, of the White Limestone Group. The majority of these microborings are preserved in the foraminifers Lepidocylina spp. within the Somerset Formation.
