Pleistocene trace fossils in the Ironshore Formation, Little Cayman, British West Indies

Oosparite grainstones of the Pleistocene Ironshore Formation, Little Cayman, British West Indies, contain the trace fossils Conichnus conicus, Ophiomorpha nodosa, and Planolites beverleyensis. The dominance of vertically-oriented trace fossils, complexity of cross-stratifications, coarseness of the sediment channel fill, and presence of several rudstone layers suggest deposition close to the seaward portion of lagoonal channels where higher energy conditions prevailed.
