Abstract
An ammonite from the Penarth Group (Upper Triassic?) at Chipping Sodbury, Avon, England, is described. This is believed to be the first ammonite to be reported from these beds or from any rocks in Britain currently regarded as Triassic in age. It is small, but its characters are similar to those of Jurassic psiloceratids rather than to those of late Triassic families.
