Also known as Loc. 13a
Where: Baja California Sur, Mexico (31.6° N, 115.8° W: paleocoordinates 31.8° N, 102.6° W)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Tepetate Formation, Middle Eocene (48.6 - 37.2 Ma)
• Collected from beds 200 feet lower that loc.# 13. 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. Determined to be middle Eocene (upper Martinez faunal similarities) by Gardner.
• bed-level stratigraphic resolution
Environment/lithology: deltaic; fine-grained, yellow siltstone and sandstone
Size class: macrofossils
Collection methods: quarrying,
• Collected by Darton. Collection studied and determined by J. Gardner. No known repository.
