Abstract

Chondrophorines have a long but exceedingly sporadic history: they dot the late Precambrian and Paleozoic and are common in modern oceans, but have not been reported from the Mesozoic or Cenozoic save for a possible Triassic occurrence (Stanley, 1986) and a single Cretaceous appearance (Stanley and Kanie, 1985). Stanley (1982) suggested that much of the fossil record of the group may languish unrecognized and misidentified in museum drawers because of its generally molluscanlike aspect and poor representation in the literature. This suspicion is validated by the discovery of a velellid chondrophorine pneumatophore in the vertebrate collections of the University of California Museum of Paleontology (UCMP).
