Where: Luna County, New Mexico (32.1° N, 107.6° W: paleocoordinates 14.0° S, 87.6° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Florida Mountains Formation (El Paso Group), Cassinian (482.3 - 470.0 Ma)

• " [...] highest 30 feet of the El Paso, the beds with Buttsoceras (Flower, 1964 p. 133). "Only at one other section, that of the Florida Mountains, have equivalents of the Cassinian been recognized. [...] The uppermost beds are dominantly dark calcarenites [...]. Here Buttsoceras has been found." (ibid. p. 147). " The beds designated as unit C by Cloud and Barnes, 35 feet thick, are developed as dark calcarenites in the Florida Mountains (Spanish pronounciation of Floreeda is used) and are named the Florida formation." (ibid. p. 149).
