    In shell/bryozoan hash from one fathom off the town of Cedar Key, Levy County, Florida, 5/2019. The upper six images depict the ontogeny of a heretofore unappreciated feature, spiral sculpture in younger shells, which character is subsequently lost as growth proceeds, concealing it under a layer of callus. SEMs produced in collaboration with Dr. Ann Heatherington, Dept. of Geology, University of Florida, Gainesville, FL.
