Loma del Pterodaustro fossil site (Cretaceous of Argentina)

Where: San Luis, Argentina (32.4° S, 67.2° W: paleocoordinates 38.2° S, 39.3° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Lower Member (Lagarcito Formation), Cretaceous (145.5 - 66.0 Ma)

• member-level stratigraphic resolution

Environment/lithology: lacustrine - small; mudstone

• The fossil association and the geological evidence indicate that the Lagarcito Formation represents a perennial shallow lake situated in an alluvial plain where detrital sedimentation an semiarid climatic conditions predominated (Chiappe et al., 1995).
