Unnamed tributary of Pontuz Creek, near Gran Colle and Dogna (Triassic of Italy)

Where: Udine, Italy (46.5° N, 13.3° E: paleocoordinates 11.8° N, 20.8° E)

• coordinate stated in text

When: Rio del Lago Formation, Julian (235.0 - 232.0 Ma)

• Lower part of Rio del Lago Formation, low Carnian (Julian)

•A Julian...palynomorph association is found in the section marked by the presence of Concentricisporites bianulatus, Parcisporites spp., Duplicisporites verrucosus, Enzonalasporites vigens, Duplicisporites grannulatus and Araucariacites australis. Concentricisporites bianulatus is restricted to the palynomorph Assemblage 1 of Preto et al. (2005) that is typical of the lower Julian. The early Carnian bivalve Myophoria kefersteini also occurs.

•The unit where the specimens were collected is referred to the Rio del Lago Formation of the close Cave del Predil (formerly Raibl) area. The horizon with the specimen MFSN 27285 occurs about 10 metres above a 12m thick bank of oolitic limestone characteristic of the lower part of the formation.

Environment/lithology: deep subtidal ramp; black, gray, yellow limestone

• The depositional environment of the lower-middle part of the unit is considered a subtidal carbonate-clastic ramp
• MFSN 27285 comes from the lower part of an 8m thick section consisting of an irregular alternation of dark grey to blackish, bioturbated to nodular, often molluscs-rich limestone beds, and levels of blackish dark greenish, clayey marls. MFSN 27285 was preserved in a 20 cm thick blackish limestone bed, grey or pale yellow when weathered.

Size class: macrofossils
