N. church Madonna Peraries, Rio Seazza valley (Triassic of Italy)

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)

• "lower-middle part of the Dolomia di Forni Formation...age, based on the conodont fauna, is Alaunian 2-3 (middle Norian)"

•Dolmomia di Forni "spans the Alaunian 2 - Sevatian 1 interval"; middle-late Norian (Dalla Vecchia 2006)

• bed-level stratigraphic resolution

Environment/lithology: basinal (); pyritic, black, gray dolomite

• "Sedimentation [occurred] in a depositional basin under anoxic conditions"
• "The stratigraphical section where the new specimen was found revealed about 35 m of well-bedded dolostones. They consist mainly of thin (5-100 mm), slightly graded beds, alternating with sets of very thin plane-parallel lamina. They are completely recrystallized and, in particular the sets of lamina, are rich of organic material, optical opaque pyrite and perhaps clay minerals. The colours of the rocks are generally black or dark grey. These alternating thin beds and sets of lamina are interupted by slump-bedding and black chert nodules or bands"

•"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
