Travenanzes Formation (Italy)

The Travenanzes Formation is a Late Triassic (early Carnian, or early Tuvalian in the regional stratigraphy) limestone, marl and dolomite formation in the Southern Limestone Alps in Trentino-Alto Adige, Italy. ^[1]

Description

Stratigraphy of the Dolomites

The Travenanzes Formation is conformably overlain by the Dolomia Principale, ^[2] and overlies the Heiligkreuz Formation separated by an unconformity. Deposition of the formation took place just after the Carnian Pluvial Event (CPE). ^[3]

Fossil content

The following fossils have been described from the Travenanzes Formation: ^[1]

Ichnofossils

• Atreipus sp. ^[4]
• Evazoum sp. ^[4]
• Grallator (Eubrontes) ^[4]
• Crocodylomorpha indet. ^[5]
