It was identified that Planolites and Skolithos were dominant [56,57]. The Planolites existed as elliptic or circular wormholes on the cylindrical surface of the well cores, parallel to the bedding plane (sketched by yellow dotted lines in Figure 6b,d,f,h) . These elliptic or circular wormholes occurred in the muddy layers and were filled with ...Portugal.

and marine trace fossils such as Skolithos (Ket-ner, 1968).

Based on measured sections in Southern NevadaMarine nutrient supply is likely controlled by the bar's morphology.
