Research

New specimens of Pelagiella exigua with associated impressions of two clusters of chaetae, providing new information on the anatomy of this taxon, are described from the Cambrian Kinzers Formation (Pennsylvania, United States) by Thomas, Runnegar & Matt (2020), who infer the occurrence of a pair of chaeta-bearing appendages extending from the anterior body wall or foot of the animal (unique among living and extinct molluscs), and interpret Pelagiella as the earliest known stem gastropod.^[152]
