Uncatalogued fossil crabs from Antigua and Bermuda deposited in the Department of Paleobiology, Smithsonian Institution, National Museum of Natural History (USNM) includes the remains of the hermit crab Coenobita Latreille, 1829 and the land crabs Gecarcinus Leach, 1814 and Cardisoma Latreille, in Latreille, Le Peletier, Serville & Guerin, 1828. Fossil remains of terrestrial crabs are uncommon in the fossil record due to a number of preservation biases, thus, even isolated or fragmentary, their fossils aid in our understanding of the evolution and geographic distribution of these taxa through time. The remains of Cardisoma and presumably Gecarcinus from the late Pleistocene of Bermuda represent the first record of fossil crustaceans from the island, and one of the only fossil records of the genera known to date, whereas the fossil hermit crab remains from the Holocene of Antigua represent the second record of fossil Coenobita worldwide.
