Mollusks from late Mesozoic seep deposits, chiefly in California Kaim, Andrzej Jenkins, Robert G. Tanabe, Kazushige Kiel, Steffen Zootaxa 2014 3861 5 401 440 [151,341,1396,1422] Gastropoda GBIF Animalia Vetigastropoda 12 413 Mollusca order   Description.Low-spired and fast-expanding shell. The ornamentation consists of orthocline to slightly prosocline axial ribs and much weaker spiral ribs with small and sharp knobs at the intersections. Aperture and apex not preserved.   Material and occurrence.Single outer mould (GZG.INV.84980) from Rocky Creek (probably Valanginian, Early Cretaceous).   Remarks.The style of coiling resembles somewhat that of peltospirids, e.g. the “scaly foot gastropod” or  Peltospira( McLean 1989; Warén et al.2003). Also the style of the axial ribs and the knobs is reminiscent of Peltospiridae. However, there are several similar vetigastropods, e.g.,  Granata Cotton, 1957. Unfortunately the aperture is not preserved and we are unable to substantiate this preliminary identification.
