Achomitzer Berg (Triassic of Italy)

Also known as Karnischen Alpen, Carnic Alps

Where: Udine, Italy (46.5° N, 13.5° E: paleocoordinates 4.6° N, 25.4° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Tirolites cassianus ammonoid zone, Olenekian (251.2 - 247.2 Ma)

• This fauna is described as being "[limited to the upper Buntsandstein]", which would make it Anisian in age (Frech 1912). However, Tirolites cassianus and Costatoria costata are generally known from the Lower Triassic. An Olenekian age has therefore been assumed.

• group of beds-level stratigraphic resolution

Environment/lithology: marine; lithology not reported

Size class: macrofossils
