FIGURE 11 Bahamian ichnology. (A) Cross sections of Conichnus conicus in cross-bedded Late
Pleistocene grainstone (horizontal surface), Harry Cay, Little Exuma. Scale bar ¼ 7 cm.
(B) Mounded topography created by the deep-burrowing callianassid Glypturus acanthochirus
on the wide intertidal zone of Pigeon Creek lagoon, San Salvador. (C) Ocypode quadrata burrow
opening with radiating trackways, East Beach, San Salvador. Scale bar ¼ 12 cm. (D) Mature
O. quadrata ghost crab, same locality as C. About 10 cm from side to side. (E) Casts of typical
O. quadrata burrows made by K. Seike, same location as C. Scale bar ¼ 10 cm. (F) Casts of the
complex burrow of the shrimp Upogebia vasquezi . One shrimp occupies each tube, a male in
one and a female in the other, and the tubes are surrounded by a thick, unified, lining with large
