Where: Friuli-Venezia Giulia, Italy (46.4° N, 12.9° E: paleocoordinates 26.4° N, 16.1° E)
• coordinate estimated from map
• small collection-level geographic resolution
When: lower Member (Dolomia di Forni Formation), Alaunian (215.6 - 212.0 Ma)
• Outcrop F1 in the middle part of the lower member of the Dolomia di Forni Formation; lowermost part of Alaunian 3 (middle Norian)
•Dolmomia di Forni "spans the Alaunian 2 - Sevatian 1 interval"; middle-late Norian (Dalla Vecchia 2006)
• group of beds-level stratigraphic resolution
Environment/lithology: basinal (); brown, gray dolomite
•"The Dolomia di Forni is composed mainly of dark, often cherty, well-bedded dolostone that is frequently thinly laminated and sometimes slumped. Thicker laminae are graded and represent distal turbidites...the basinal facies preserving the tetrapod remains are composed mainly of distal turbidites and carbonate mud deposited by fallout"
Size class: macrofossils
Collected by Ruggero Tonello in 1980s, 1994
Collection methods: bulk, mechanical,
• Collected from a scree slope
