Amberleya cf. dilleri Stanton, 1895

Fig. 4D View Fig .

Material.— One specimen from NW Berryessa (site 10; UCMP 555090 View Materials ), and two fragments from the Franciscan Little Indian Valley terrane (site 6) .

Discussion.—These specimens have a stronger second tuberculate cord below the main one compared to Stanton’s (1895) type specimens of A. dilleri , and lacks the nodular subsutural cord of A. morganensis . Because the specimens are rather poorly preserved, we only hesitantly assign them to A. dilleri .

Stratigraphic and geographic range.—Tithonian (Upper Jurassic) to Valanginian (Lower Cretaceous), restricted to seep carbonates at NW Berryessa of the Great Valley Group and Little Indian Valley terrane , Franciscan Complex; California, USA.
