Geography comments: "west of the Cuyama River in a tributary of Tennison Canyon, 34º 51' 05" N, 119º 33' 13" W, at an elevation of 3120 feet"
"All fossils of the Vedder local fauna were collected from an area approximately 60 meters by 30 meters near the top of a small tributary canyon of Santa Barbara Canyon" (Munthe 1979)
said to be Hemingfordian based on the mammals and to belong to the "Temblor" stage based on marine invertebrates found west of the locality
thought to be about 17 Ma based on correlation with other faunas, meaning Early Miocene
