Reference after species name indicates primary reference. Polarity intervals from ATNTS04 (Lourens et al., 2004). T = top, B = bottom, LO = last occurrence, FO = first occurrence, LaO = last abundant occurrence, FaO = first abundant occurrence, FcO = first common occurrence. sin = sinistral, dex = dextral.
