Where: Trentino, Italy (46.5° N, 11.6° E: paleocoordinates 8.2° N, 22.0° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Frankites regoledanus ammonoid zone, Marmolada Conglomerates Member (Cassian Formation), Longobardian (242.0 - 235.0 Ma)

• Also called Tufi a Pachicardie. The ammonoids from the Pachycardientuffe indicate a Late Ladinian age (URlichs 1977: 17, 1994: 33). Recently, the updated base of the Regoledanus Zone has been fixed at the Tschapidbach/Rio Cipit (Seiser Alm) and the eastern tributary of the Frommerbach/ Rio Frommer at the base of the Marmolada Conglomerate 1 by Mietto et al. (2012, fig. 9). Consequently, the occurrences of Myophoria kefersteini at the Seiser Alm dated in the early to late Regoledanus Zone. Material from the Pachycardientuffe, now named Marmolada Conglomerates, is recorded from four localities at the Seiser Alm.

•Further notes (from Ulrich 2014, entered by PJW): Pachycardienstuffe & F. regoledanus zones are the top of hte Longobardian, not the base of the Julian. Overlies Upper Schlern Dolomite and Rossetta dolomite (both in the Protrachyceras neumayri zone of the Longobardian). Base parallels Schlernplateau beds and traditional Cassian Dolomite; lowet beds of Cassian formation.
