Tenadas de Cuestalomo tracksite (CLST) (Cretaceous to of Spain)

Also known as Salas de los Infantes, Costalomo, Costalmo

Where: Castilla y León, Spain (42.0° N, 3.2° W: paleocoordinates 33.0° N, 7.9° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Pinilla de los Moros Formation (Urbión Group), Late/Upper Hauterivian to Late/Upper Hauterivian (136.4 - 125.5 Ma)

• "Weald facies"; also assigned to Piedrahita de Muñó Fm./Pedroso Gp.

• bed-level stratigraphic resolution

Environment/lithology: coarse channel fill; tabular, burrowed, coarse-grained sandstone and bioturbated, red mudstone

• abandoned channel
• "The Costalomo tracksite (Figs 1 and 2)is at the top of a 2-m thick sandstone bed with sheet-like geometry and a gently concave upward base and planar top. The top of the bed shows undulations that correspond to bedforms. The sandstone bed contains large-scale cross-trough stratification. Linguoid ripple marks and megarip- ples are preserved on the plane on which the footprints appear. This bed also shows a fining upward sequence. Overlying this sandstone bed are red mudstones with millimetre- to centimetre-scale lenticular sandstone intercalations, some of them with internal ripple lamination. Still higher in the succession, at least three thin sandstone tabular beds 8–14 cm thick are intercalated with the red mud- stones. These beds are densely bioturbated by vertical burrows and also contain dinosaur footprints."
