Also known as Marine reptile site

Where: Santiago, Chile (33.4° S, 71.7° W: paleocoordinates 35.5° S, 59.2° W)

• coordinate stated in text

When: Estratos de Quebrada Municipalidad Formation, Early/Lower Maastrichtian (70.6 - 66.0 Ma)

• The EQM is considered to be Maastrichtian in age based on bivalves such as C. acuticostatum and P. hanetiana (Pérez-D’Angelo and Reyes, 1978). Recently this determination has been constrained by a radiometric date on 90Sr/89Sr obtained from bivalve shells (Suárez and Marquardt, 2003) that indicated an age of 69 +- 01 Ma (early Maastrichtian).

Environment/lithology: marine; fine-grained sandstone and conglomerate
