Lerici, La Spezie (Triassic of Italy)

Also known as Lerici

Where: Liguria, Italy (44.1° N, 9.9° E)

• Paleocoordinates: 17.1° N, 30.7° E (Wright 2013)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Montemarcello Formation, Carnian (237.0 - 228.0 Ma)

• upper part of formation; also called the "Verrucano" time interval. Tracks found on five levels (a1, a2, a3; b1, b2)

• group of beds-level stratigraphic resolution

Environment/lithology: fluvial; bioturbated, gray, green sandstone and claystone

• "arenitic with a few thin clayey inter-beds; the sands overlie micro-conglomeratic bodies up to 1 m thick...Two-dimensional ripple marks (with wavelengths of nearly 20 cm), larger ripples (wavelengths of 120 cm), interference ripples, and mud cracks were recognized. The arenitic beds are also characterized by internal structures such as accretionary laminae, coalescent bodies, low-angle lamination, and cross stratification. Some arenitic levels are deeply bioturbated both by simple vertical tubes and by larger horizontal ones. Rare small wood fragments were recognized. Small channels, up to 1.5 m over a very short distance, cut the arenitic bodies."

Size class: macrofossils

Preservation: mold/impression, trace
