Repair of gastropod drillholes in a platidiid brachiopod from Fiordland, New Zealand

Two morphologies of drillhole, probably attributable to gastropods, have been recognized in specimens of the small extant New Zealand platidiid brachiopod Neoaemula vector, collected from Fiordland, New Zealand. Some of these drillholes have been repaired, and these repairs occur in two different ways. The thin replacement shell has both primary and secondary layers and in some cases is punctate. Drillhole repair is virtually unknown among living brachiopods, but this may due to successfully repaired drillholes being classified as abandoned or incomplete.
