Where: Italy (46.6° N, 11.9° E: paleocoordinates 8.1° N, 22.2° E)
• coordinate based on nearby landmark
• local area-level geographic resolution
When: Longobardian (242.0 - 235.0 Ma)
• According to Urlichs (2017), The type locality and horizon of Protrachyceras “aequinodosum” remain uncertain, because its origin from the Cassian Formation sensu Mojsisovics (1879) has been questioned, and the Wengen Formation has been supposed to be the type formation (Mojsisovics 1882: 126).
