Las Cerradicas tracksite (Jurassic to of Spain)

Also known as Galve

Where: Aragón, Spain (40.7° N, 0.9° W: paleocoordinates 31.6° N, 8.6° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Villar del Arzobispo Formation, Kimmeridgian to Kimmeridgian (157.3 - 145.0 Ma)

• above levels of Cuesta Lonsal site

•Age of Villar del Arzobispo Formation constrained to Kimmeridgian-Tithonian by Campos-Soto et al. (2017), rather than Tithonian-Berriasian of older literature

• bed-level stratigraphic resolution

Environment/lithology: terrestrial; bioturbated, fine-grained, micaceous, gray, sandy, calcareous limestone

• near the contemporaneous shoreline, "fluvial-dominated delta plain depostis, showing local traces of subaerial exposure and scarce evidence for tide reworking."
• "this bed is a sandy limestone. Crystalline calcite forms the matrix for the abundant fine-grained angular quartz. The thin-section shows minot elements such as muscovite, garnet, dark minerals, calcareous fragments and agglutinated foraminifera. Sedimentary structures include penecontemporaneous ripple marks, vertical U-shaped burrows...and vertical burrows."

Size classes: macrofossils, microfossils

Preservation: mold/impression, trace
