Non-echinoid echinoderms are poorly known from the fossil record of Jamaica and only occur as disarticulated plates. Only crinoid columnals have been reported hitherto. However, asteroid marginal ossicles and ophiuroid vertebral ossicles are also common locally. Three species of isocrinid are recognised: cf. Cenocrinus asterius (Linné) from the Lower Pleistocene, Diplocrinus sp. from the Miocene, and an isocrinid sp. indet. from the Eocene. The microcrinoid Applinocrinus cretacea (Bather) and an indeterminate comatulid are both known from the Upper Cretaceous. Asteroid marginal plates (astropectinids and/or goniasterids) have been recovered from one Oligocene, two Maastrichtian and three Eocene localities. Ophiuroid verterbral ossicles have been recovered from a patch reef in the back-reef lagoonal facies of the Upper Pleistocene (last interglacial) Falmouth Formation.....
