Abstract:
Two specimens of the Cretaceous genus Pictetia Uhlig, 1883, have been found in the Cottonwood District, northern California, the first record of this genus in North America. The larger specimen is a septate whorl fragment from the Brewericeras hulenense zone that is associated with Douvilleiceras mammillatum. It is identified as Pictetia sp. The smaller specimen is a septate fragment of one and a half whorls from the Oxytropidoceras packardi zone associated with Cleoniceras . It is identified with the type species, Pictetia astieriana Orbigny, 1842, previously recorded from Europe. A review of the genus Pictetia suggests that species assigned to the genus have an open coil with a rounded dorsum. The occurrences of these Tethyan elements in the Albian fauna of the Cottonwood District suggest easy communication for many Cretaceous taxa between northern California and the Tethyan realm of Europe, the Caucasus, and Madagascar.
