Also known as LACM 4956, CAS 725, UCMP V74021
Where: Kern County, California (35.3° N, 118.5° W: paleocoordinates 35.2° N, 113.3° W)
When: Round Mountain Member (Temblor Formation), Langhian (16.0 - 13.8 Ma)
• Locality described as being in "Round Mountain Silt", Barstovian
•
•The Round Mountain Silt has been dated to 16.1–14.5 Ma based on magnetostratigraphy, strontium dating, and diatoms indicative of the Denticulopsis lauta A biozone (16–15 Ma). More specifically, the middle portion of Round Mountain Silt (including the bone bed) has been correlated with Chron C5Br, indicating an age range of 16.0–15.2 Ma [193]. (Marx & Fordyce, 2015)
