Favosites "Emmonsia" tuberosa found in the Jeffersonville Limestone in Jefferson County, Kentucky (Louisville). Originally named by Carl Rominger in 1876. Identified using Silurian and Devonian Corals of the Falls of the Ohio by E.C. Stumm, 1964 (page 68). Coral existed in the Middle Devonian Period (397 to 385 million years ago consisting of the Givetian and Eifelian Stages).
Described as "Corallum hemispherical to elongate subcylindrical, composed of pentagonal or hexagonal corallites averaging 3 mm in diameter interspersed with smaller trigonal or tetragonal corallites. All corallites with thin walls. Squamulae prominent but relatively short, typically about 1 mm long. Mural pores very large, either parallel or offset biserial. Tabulae typically incomplete, wavy, closely set."
