Where: Morocco (32.3° N, 9.3° W: paleocoordinates 32.3° N, 9.2° W)
• coordinate estimated from map
• local area-level geographic resolution
When: Middle Pleistocene (0.8 - 0.1 Ma)
• layer J; Tyrrhenian
•It seems from Texier et al., 2002 (Quaternaire vol. 13) that this level was subsequently destroyed by continued quarry excavation. My interpretation from this publication and Roberts et al. 2006 (in Quat. Science Reviews) is that layer J is around or older than 500,000 yrs old. Occhietti et al (2002; Quaternaire) performed amino acid racemization on Patella from museum collections of layer J, and while these analyses yielded very low concentrations, they suggest this layer is Stage 15. Stearns (1978; GSA Bulletin) correlates to Stage 17.
• bed-level stratigraphic resolution
Environment/lithology: coastal; grainstone
Size class: macrofossils
