Las Tetas de Cabra Formation

Las Tetas de Cabra Formation in Mexico preserves fossils from the Wasatchian age of the Early Eocene and is best known for the Lomas Las Tetas de Cabra fauna of Baja California, which records a terrestrial ecosystem from the beginning of the Eocene after the Paleocene transition. Its fossils are dominated by mammals, including early hoofed animals and carnivorous forms, but also include reptiles, amphibians, fish, gastropods, and plants. Together these remains provide a broad view of the ancient environment. Since studies published from the 1960s onward, the formation has been recognized as one of Mexico’s key early Eocene vertebrate localities and as important for comparing Wasatchian faunas across North America.
