Coste dell'Anglone tracksite (Jurassic of Italy)

Where: Trentino-Alto Adige, Italy (46.0° N, 10.9° E: paleocoordinates 32.4° N, 16.2° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Rotzo Formation (Calcari Grigi Group), Sinemurian (199.3 - 190.8 Ma)

• lower part of Rotzo Fm. ("formerly Tovel Mb."); middle-?late Sinemurian

• bed-level stratigraphic resolution

Environment/lithology: paralic; ooidal, gray grainstone and bioturbated, intraclastic, ooidal, gray wackestone

• "small supratidal ponds""supratidal flats"
• "poorly fossiliferous dark grey stromatolitic and peloidal mudstone" "oolitic limestone"; "a moderately bioturbated grey wackestone-packstone (70 cm), characterized by both rounded and angular ooids, bioclasts and intraclasts, that grades upwards to a grainstone, with centimetric oncoids and coated grains. This layer, locally eroded by tidal channels (NW-SE oriented), is followed by an oolitic grainstone (10 cm), dark grey in colour, millimetrically laminated and with fenestral fabrics; in its topmost portion it is subdivided into two millimetric grainstone layers with bird’s eyes, separated from each other and from the underneath portion by reddish surfaces. The top of this interval corresponds to the footprint-bearing horizon"

Size classes: macrofossils, microfossils

Preservation: mold/impression, trace
