Of the Ladins
The Ladinian (~242 – ~237 Ma) is the second geological stage of the Middle Triassic, preceded by the Anisian in the geological time scale and followed by the Carnian.
The Ladinian was defined by the Austrian geologist Alexander Bittner in 1892. The name of this floor refers to the Ladins, inhabitants of the Dolomites region in Italy.
The base of the stage (Anisian-Ladinian boundary) is defined by the first appearance of the ammonite species Eoprotrachyceras curionii or by the first appearance of the conodont Budurovignathus praehungaricus. The Ladinian Global Stratotype Section and Point (GSSP) is an outcrop located in the bed of the Caffaro river at Bagolino in the province of Brescia in Italy (45° 49′ 09.5″ N, 10° 28 ′ 15.5″ E),. The Ladinian-Carnian boundary is defined by the first appearance of the ammonite Daxatina canadensis.
The vertebrates of this stage include in particular the Spondylosoma and the Dicynodonts.
