Also known as Loc. 16
Where: Baja California Sur, Mexico (31.3° N, 116.3° W: paleocoordinates 31.5° N, 103.2° W)
• coordinate based on nearby landmark
• local area-level geographic resolution
When: Tepetate Formation, Middle Eocene (47.8 - 37.7 Ma)
• Paleocene and Eocene series are named the Tepetate Formation in Baja California. The strata probably underlie a large part of the region covered by latter rocks, the uppermost beds lapping over the edges of the older formations and lying on the granite of the main range. Considered based on fauna to be Middle of Upper Eocene age, restricted to middle Eocene by enterer.

Environment/lithology: deltaic; fine-grained, yellow siltstone and sandstone
Size class: macrofossils
Collection methods: quarrying,
• Collected by Smith. Collection studied and determined by J. Gardner, and C.W. Cooke (USGS). No known repository.
