Abstract
van den Ende and Donovan (2015: “Urchins on the edge: an echinoid fauna with a mixed environmental signal from the Eocene of Jamaica” Swiss J. Palaeontol. doi: 10.1007/s13358-015-0072-3 ) describe an interesting echinoid fauna from the Guys Hill Formation of Thornton, Jamaica. Based on geological mapping, this fauna should be assigned to the Chapelton Formation and not the Guys Hill Formation. A brief review of echinoids from the Chapelton Formation, including two localities in central Jamaica indicates that geographically distinct shelf edge and lagoonal assemblages are not present. Instead, the echinoids are better interpreted as open marine and restricted marine, and their distribution explained by a large-scale transgressive–regressive cycle with a ramp-type geometry.
