.... This paleoecologic study examines a carbonate hardground surface encrusted with four species of isorophid edrioasteroids: Curvitriordo stecki , Carneyella ulrichi , Carneyella pilea , and Streptaster vorticellatus . Analysis of edrioasteroid diameters, a proxy for age, shows a bimodal distribution for Curvitriordo...

... communities of edrioasteroids from Florence, Kentucky and Sharonville, Ohio. In these two occurrences, the edrioasteroids Isorophus cincinnatiensis , Streptaster vorticellatus , and Carneyella pilea utilized brachiopod and mollusk shells as hard substrates for attachment. Age structure analysis for specimens...
