Also known as UCLA loc. 7002
Where: Los Angeles County, California (34.1° N, 118.6° W: paleocoordinates 39.9° N, 88.7° W)
• coordinate stated in text
When: Tuna Canyon Formation, Middle Campanian to Middle Campanian (83.5 - 70.6 Ma)
• Distribution section says "Tuna Canyon Formation," but locality description in the appendix says unnamed formation
Environment/lithology: submarine fan; lithology not reported
•"The mollusks at CSUN loc. 153 must have undergone post-mortem transport from shallow-water sites into deep-water, submarine-fan paleoenvironments of the Tun- ca Canyon Formation. Several of the species found at CSUN loc. 153 or in the immediate vicinity (e.g., Anchu- ra phaba, Volutoderma magna, Crassatella elongata. Cymbophora triangidata, Glycymeris (Glycymerita) veat- chii, Pterotrigonia evansana, and Pinna sp.) were nor- mal-marine, shallow-depth dwellers (10 to 50 m) that also have been reported as transported remains in bathyal sub- marine-fan deposits of Campanian age in the Chatsworth Formation in the Simi Hills (Saul & Alderson, 1981)."
