DESCRIPTION

Sonninia (Papilliceras) is strongly similar to S. ( Sonninia ). The only appreciable generic difference is the presence of a row of lateral tubercles, one on each rib, persisting on the evolute compressed BC, even after the ribs have faded, or tubercles occur only on the BC. Some specimens have strigate ornament.

DISTRIBUTION

Lower Bajocian, Laeviuscula and Propinquans zones: Europe, Thailand, United States (Alaska, Oregon), Chile, Argentina and Peru. In the Subbetic domain, it is rare, occurring in the upper part of the Laeviuscula Zone of Sierra de Alta Coloma area (Jaén Province).
